Synthesis of Acetanilide By: Rick Whitely April 9‚ 2013 Organic Chemistry Lab 1; Professor J. Hutchison Recrystallization is a common method of purifying organic substances through the differences in solubility at different temperature. In this experiment‚ acetanilide was produced by acetylation of aniline with acetic anhydride. The crude acetanilide was dissolved in a solvent in a heated water bath. The solution was cooled slowly in an ice bath as crystals form out. As the compound crystallizes

SYNTHESIS OF ESTERS USING GREEN AND NON-GREEN CHEMISTRY Abstract Esters are a class of organic compounds with the general formula RCOOR’. Ester also contributes the flavor and aromas in fruits and flowers. The esterification reactions will use in the procedure‚ which are the interaction of a carboxylic acid with an alcohol‚ aided by an inorganic acid catalyst (H2SO4). Moreover‚ the green method will not use any catalyst but using heating source instead (microwave). Based on the comparison of

AQA AS Philosophy Revision Notes – Tolerance What is Tolerance? Weak and Strong Senses of ‘Tolerance’ • Tolerance requires difference – you don’t ‘tolerate’ something that you agree with. • However‚ tolerance isn’t a ‘live and let live’ attitude. • There are several ways of responding to things that are ‘different’ (with respect to attitudes and beliefs): o Someone can not care how other people live – this isn’t tolerance o Someone can not object

The purpose of this experiment is to synthesize isopentyl ester by an esterification reaction between a carboxylic acid and an ester. Carboxylic esters‚ like isopentyl acetate‚ are normally used to create artificial flavors. In the preparation of isopentyl acetate‚ esterification of acetic acid and isopentyl alcohol occurs. Esterification is an equilibrium shift to the product side using an excess of one of the starting components. In this experiment‚ the excess reagent is acetic acid because it

Chickpea (Cicer arietinum L.) is an important legume crop and its seeds are rich source of protein and fibre. It also contains micronutrients such as iron‚ calcium‚ potassium‚ phosphorous‚ and magnesium making it an integral part of daily diet of millions of people especially in the developing world. Globally‚ it is grown on an area of 11.5 million hectares with total annual production of about 10.5 million tonnes. Commercial production of chickpea is not too old in Canada. It started in 1990s and

Peter Mehnert Rhet 105 Ms. Paterson 11/14/12 Extended Synthesis: Cigarette Smoking Tobacco has played an important role in America from the beginning. It was grown as a cash crop by the Jamestown settlers in 1612‚ but over the years the popular opinion has changed about tobacco. Tobacco is used to make cigarettes‚ which have been extremely popular‚ now known to be extremely dangerous. Even the warnings on the cigarette box have changed to a statement much more alarming. In the 1960s‚ the warning

Synthesis of Information In summary‚ the articles researched were divided into four main categories. The categories all focused on something different. The categories were; the perception kids have on food‚ communities raising healthy kids‚ nutritional awareness and the school context. The first two articles had the common theme of how children view food and to find what children thought and felt about healthy food. The third article was aimed towards parents. The theme of this article was how
