In the reaction mechanism‚ a carboxylic acid‚ m-toluic acid is used to synthesize N‚N-diethyl-m-toluamide‚ also know as DEET‚ through a nucleophilic acyl substitution reaction. The reaction begins by first converting the m-toluic carboxylic acid into an acyl chlorosulfite through a reaction using thionyl chloride. The carboxylic acid is converted into an acyl chloride because the acyl chloride is more reactive. In this step‚ hydrochloric acid is formed from a hydrogen on the carboxylic acid and a

RECRYSTALLIZATION OF ACETANILIDE ABSTRACT Recrystallization is the primary method for purifying solid organic compounds through the differences in solubility at different temperatures. In this experiment‚ a suitable solvent was first determined. Acetanilide was produced by acetylation of aniline with acetic anhydride. The crude acetanilide was dissolved in a solvent in a heating water bath. The hot solution was filtered and the filtrate‚ cooled slowly in an ice bath as crystals started forming

Analysis of Hydrocarbons Jessa Grace B. Castillo* and Stephanie Chua Department of Chemistry‚ University of Santo Tomas‚ Manila‚ Philippines ______________________________________________ Hydrocarbons are organic compounds containing only hydrogen and carbons and further divided in major types. Hydrocarbons react differently in reagents. The basis of determining an unknown hydrocarbon is due to the differences in reactions of hydrocarbons. An unknown compound is determined using tests.

Synthesis of Salicylic Acid from Wintergreen Oil Objective – Preparation of salicylic acid (organic synthesis) from methyl salicylate utilizing previously used procedure from the nineteenth century. The final product will then be evaluated in comparison to salicylic acid made from benzene. Discussion – In this synthesis‚ methyl salicylate is the starting material or precursor and salicylic acid is the target product. It is the major constituent of wintergreen oil. The difference in structures

abilities and career goals‚ I have decided to pursue my graduate studies in the field of Chemistry. While my graduate study has helped me develop an insight into my intended area of specialization and the ability to relate developments in fundamental concepts to analytical chemistry‚ it still cannot support my desire for research and design. I therefore strongly believe that a detailed research chemistry from your university will be a step forward in achieving my objective of launching a career
