Acetic anhydride

Heroin, known as one of the deadliest recreational drugs, is making a comeback to the eastern shore. Heroin, derived from the seed of a poppy plant, has a unique molecular structure, making it an interesting topic of discussion. Using this highly addictive drug destroys both your mind and your body. Sudden discontinued use, also known as cutting off “cold turkey”, can bring about intense symptoms of withdrawal, leaving the user feeling incredibly ill, helpless, and desperate for the drug. Heroin…

A small burette funnel was filled with column packing solvent at mobile phase, high boiling petroleum, in this case hexane (and then 10%acetone hexane mixture), and Alumina as stationary phase. When adding the sand and the alumina they have to be first mixed with the hexanes in order not to disturb the column. The Lycopene is Red- Orange and more attracted to alumina due to its high degree of Unsaturation, which can be expected to be eluted after Yellow-Orange Carotene pigments. And the other…

In this lab we took salicylic acid, then reacted it with acetic anhydride in the presence catalyst and heat forming crude acetylsalicylic acid or aspirin. My lab group and I, then proceeded to purify the product with ethanol, and verified its purity with its known melting point. At the end of this lab I was left…

The purpose of my experiment is to examine the amount of BPA levels in food packaging for infants. I believe that the BPA levels in baby food varies considering food packaging size, texture, material, and color. To help me during my experimental process I have found several articles,that explain each concept of my experiment; also providing background information. Kubwabo, C., Kosarac, I., Stewart, B., Gauthier, B. R., Lalonde, K., & Lalonde, P. J. (2009). Migration of bisphenol A from plastic…

Carbonyl compounds undergo various types of reaction. In these reaction the carbonyl carbon or carbonyl oxygen is prone to attack generally by a nucleophile. Different types of carbonyl compounds undergo different types of reactions and the mechanisms of them are also different. The products or by-products or intermediate products of these reactions are very much useful in laboratory synthesis, industry etc. here we will discuss some very much important reactions which are very important for…

It is also conceivable that, at lower pH, depurination can occur via protonation of the purine nucleobase at both N1 and N7. The presence of the 2′-OH has a significant effect on the nucleoside’s susceptibility to depurination. For example, guanosine and adenosine are more resistant to depurination compared to deoxyadenosine and deoxyguanosine. Deoxyadenosine itself depurinates 1200 times faster than adenosine (York, 1981). Interestingly, N-acyl-protected purine nucleosides (particularly…

combined filtrate concentrated at reduced pressure to remove THF , then the aqueous residue extracted with 2 X 40 ml ethyl acetate. The combined ethyl acetate layers washed with water and dried over MgSO4. To this ethyl acetate layer, 2ml of glacial acetic acid added and stirred the reaction mixture at room temperature to afford acetate salt of 1-(2-amino-1-(4-methoxyphenyl)ethyl) cyclohexanol…

2). HEROIN: Heroin is formed by conversion of morphine which does not require complex equipmentation but more elaborate chemical operation under which morphine is refluxed with acetic anhydride for about 5 hours results into the formation of Diacetyl morphine, i.e., heroin. It is seperated when the solution gets neutralize with sodium carbonate or washing soda in which heroin gets separated as a precipitate. It is collected and purified by treating it with hydrochloric acid by which Heroin…

Its derivatives, acyl halides, anhydrides, esters, amides and nitriles, are used in making target products such as flavoring agents, internal plasticizers, pesticides, dyes, textile treatment agents, fungicides, and pharmaceuticals through further reactions of substitution, catalytic reduction…
