Lab smell of each ester was determined and recorded

Lab 6 –Synthesis of Esters (Esterification)  INTRODUCTION: Esters arechemical compounds which are synthesized from the condensation of a carboxylicacid and an alcohol, a process known as esterification. Triglycerides, made ofthree fatty acids and a glycerol, are common examples of naturally occurring estersfound within living organisms, being the main constituents of animal fats andoils. Due to their distinctive odors, esters are also used within the productionof fragrances and artificial flavors.                                 These variationsin scents are generated by reacting alcohols and carboxylic acids of differentstrengths and configurations. As shown in Equation1, esterification reactions consist of the substitution of the hydroxylgroup (OH) on an organic or inorganic acid, by either a primary, secondary ortertiary alcohol; creating water as a byproduct.      Equation1: General Esterification Equation In this investigation,various alcohol and carboxylic acid pairs were reacted amongst each other toform esters with the catalytic aid of sulphuric acid, H2SO4(aq).Hereafter, the distinct smell of each ester was determined and recorded throughthe wafting technique.
