SYNTHESIS OF 1-PHENYLAZO-2-NAPHTHOL ABSTRACT Amines are compounds composed of nitrogen atoms bearing alkyl or aromatic compounds. Amines undergo interesting reactions, one of which is with the reaction with nitrous acid producing an azo dye. In this study, the experiment focused on synthesizing an observing the physical properties of Sudan-1. Sudan-1 is of the most common dyes found in waxes, oils and in some food ingredients specifically curry and chilli powder. Furthermore, this study aimed to understand the mechanism behind the synthesis of 1-phenylazo-2-naphtol. To be able to synthesize Sudan-1, preparation of phenyldiazonium chloride solution and ÃŽ ²- naphthol solution were done. Ingrain dyeing was also done in this experiment. The†¦show more content†¦The main reaction that occurred in the preparation of phenyldiazonium chloride solution was diazotization reaction. Diazotization is the reaction between a primary aromatic amine and nitrous acid at cold temperatures to diazonium salt compound.[2] Figure 1 below is the reaction exhibited by the phenyldiazonium chloride solution. As this experiment aimed to synthesize Sudan-1, two steps are done. The first step would be the reaction of a primary aromatic amine to produce a diazonium salt as seen in Figure 1. The second step, then, is the reaction of the diazonium salt with a strongly activated aromatic syste,l known as coupling reactions. Azo coupling is the reaction between a diazonium compound and aniline, phenol or other aromatic compound which produces an azo compound.[5] In this experiment ÃŽ ²-naphthol couples with the diazonium salt. Figure 2 below shows the coupling reaction of the benzene diazonium chloride with ÃŽ ²-naphthol and having the product of Sudan-1. Furthermore, figure 3 below is the summary of reactions of the synthesis of Sudan-1 in this experiment. Figure 3 Summary of Reactions in Synthesizing Sudan-1 Figure 3 Summary of Reactions in Synthesizing Sudan-1 In this experiment, a filter paper was used to undergo ingrain dyeing. Ingrain dyeing is an irreversible chemical reaction of the diazonium salt solution and the activating aromatic solution. An orange-red filter paper was produced after such procedure.

The Biological Perspective On Homosexuality Essay

Cover Page One’s attraction to another can be led by many factors. Many may believe that feelings and emotions play a role, but could it be our genetic make-up determines our life partner? It is widely favored that homosexuality stems from one’s environment and the people around them. Although less favored, the theory that genetics plays a role in homosexuality is concrete. In agreeance, Heffner Johnson (2003) states the hypothalamus, a highly significant region of the brain, plays a role in sexuality. This theory is supported by evidence homosexual behaviors in young age (Bellamy, 2012). According to Heffner Johnson (2003), Darwin believed that sexual orientation is not a choice, it emerges from adolescence without prior sexual experience. Many experiments in the biological perspective have been done to support that nature plays a role in homosexuals. Biologist have found anatomical, genetic, and endocrine evidence in homosexuals. Alfred Kinsey was one of the first researchers to study homosexual behavior (Heffner Johnson, 2003). Alfred intention was to see how many people were engaged in homosexuality. In this study, participants replied â€Å"no† when using the term homosexual relations, but replied yes when asked have they have sex with the same gender. The findings in this study highlighted that 30% of the males had experienced same sex interaction (Heffenr Johnson, 2003).

A Day In Court Free Essays

Professor Brian D. Heffner 7 December 2012 A Day In Criminal Court This week I had the opportunity to sit In on criminal court proceedings. I chose to visit the Oakland County Court House for the day and noticed quite a few things through out the whole experience. We will write a custom essay sample on A Day In Court or any similar topic only for you Order Now I have been to a few courts In the past, criminal, traffic, and family, but never In the Oakland County bulldlng. There were many details of the proceedings, the Image, and even the condltlons of everything from the bulldlng Itself to the people Involved that I found particularly Interesting. The first thing I hought when I entered the bulldlng was that It was not crowded. In previous vlslts to troy courts the place was packed, let alone confusing. This courthouse was different. The hallways were very modern and clean and it felt fresh to me, not dark and dismal like it could have been. (l guess I have to also consider that I didn’ t have any charges against me so I wasn? t entering the building expecting to hate being there) I was surprised by the security measures. It seemed as if it was too easy to get through. I expected to have three or four metal detectors lined up for a big crowd, but there was only one. Right away I got the sense that the size of the building was not reflective of the amount of cases per day it accommodates. After speaking with one of the guards I was referred to the criminal court room rather than the family court, due to what he called a more interesting day.? . The courtroom itself I thought was way too small. There were only two and a half rows for people to sit and watch, forcing many people to have to wait outside. That I thought was not a well thought out design. There is tons of extra hallway space that they could have stretched the room out to make it bigger so you wouldn’t run into those kinds of problems. The room also had extravagant fixtures hanging from the ceiling. I don’t really understand the purpose of them, they may even have been lights, but they Just looked like a waste of money. I dont think they serve any other reason than to look pretty, and if that’s the case, they could have spent the money on the room extension. That’s Just my opinion of the building; another thing that struck me was the people involved. As I looked around the court room, I saw lawyers, citizens, guards, and of course the Judge. The Judge, I was informed, was the night Judge filling In for someone. I was warned by my buddy, the guard, that he would be sluggish, but I thought It flowed nicely. I must first speak of the lawyers because they bothered me the most. These lawyers were slobs! I realize that you may not make a whole lot of money being a public defender, but you could at least dress appropriately. One of these lawyers had his whole hem hanging out with string following him everywhere. This guys pants were wrinkled and his hair completely void of any type of brushing. I would never hire any one that looked Ilke that. and I would be scared If I had him assigned to me. Another lawyer, a woman this time, was the most horrifying thing I have ever seen. Before she even came in the wanted a new lawyer because she was as dizzy. When she walked in I realized they had made a huge understatement. This woman had the most disgusting mess of hair on top of her head and she kept scratching it. It was like a huge crimped, teased, knotty mess. I couldn’t believe that she would walk into a courtroom like that. Oh my God she was a mess! I don’t understand how she could represent anyone looking like that. There was only one professional looking lawyer and he was the prosecutor. Everyone else looked third rate compared to him. The other group of people I looked at was the criminals. There was definitely a mixed group of people there. There was one lady in her 40’s that was wearing a long fur coat and all the Jewelry in the world, and you could Just tell she was ashamed to be there. Her husband wouldn’t even sit in the courtroom with her. I really would have loved to know what she did wrong, but with all the bench conversation you never got to hear her crime, Just her dismissal. Another guy that had charges against him wasn’t even allowed in the courtroom ecause he didn’t have the right shoes. I thought that was completely unfair. He was outside the courtroom explaining that he didn’t have any money to buy good shoes for the day, but they still wouldn’t let him in. I guess all this stuff has been pretty superficial, but what really bothered me was how each of the cases was handled. I always thought that the public could view any courtroom proceeding, but I felt extremely short changed. In fact I think it was unfair to the criminals as well. It seemed like every case was decided at the bench before even saying what the charges were. I know I sat through three hours of court and left only knowing what two of the cases was really about. When the incarcerated people were brought out it looked like they were clueless as to what was going on, because they couldn’t hear any of it. They looked shocked sometimes when hearing the decisions as if they didn’t know what was happening to them. I know that I was shocked when I heard some of the verdicts because I had no idea what the crime was For the most part they Just announced codes not allowing the common person to understand a thing they’re talking about. After every decision the lawyer had to break it down to their own words to the clients. That annoyed me so much. I was also disgusted with one case in particular where they actually did describe the crime. A man and a woman had both committed armed robbery and in the process hospitalized two victims. Their lawyer had the nerve to ask for $1000 bail for the two of them, pointing out the families of each of the criminals in the courtroom, explaining that they both had newborns to take care of. This lawyer had a 6 year old child in the courtroom to hear his father receive a $50, 000 bail. I Just think that was wrong. The lawyer knew there was no way in the world he was getting his client off, the guy had a rap sheet longer than the Bible from 4 different states, but he chose to put that kid through that. I don’t get that. I guess overall my court experience was a pretty good learning experience. I learned to appreciate my lawyer a 100 times more Just for his wardrobe alone. I learned that you always need appropriate shoes even if your clothes are as crappy as ever. I learned that the city of Oakland County prefers style to space accommodations, and most importantly I learned that is cheaper to obey the law than to break it. How to cite A Day In Court, Papers
