In this work‚ biodiesel (ethyl ester) was prepared from waste cooking oil collected from a local restaurant in Halifax‚ Nova Scotia‚ Canada. Ethyl alcohol with sodium hydroxide as a catalyst was used for the transesterification process. The fatty acid composition of the final biodiesel esters was determined by gas chromatography. The biodiesel was characterized by its physical and fuel properties including

Synthesis of Methyl Salicylate from Aspirin Esters are a class of organic compounds. An ester compromises an organic or inorganic acid in which one or more hydroxy (OH) groups have been replaced by and alkoxy (O-alkyl) group. For example‚ the simplest ester‚ methyl formate (CHOOCH3)‚ is made up of formic acid (CHO-OH) in which the hydroxyl group has been replaced by a methoxy group (-OCH3). Similarly‚ ethyl acetate (CH3CO-OCH2CH3) is made up of acetic acid (CH3CO-OH) in which the hydroxy group

Esterification is a reaction between a carboxylic acid and an alcohol to form an ester. Refluxing the two reactants with an acid catalyst forms the ester. Fischer Esterification was discovered in 1895 by the German chemist‚ Emily Fischer and Arthur Speier. The reaction is also sometimes known as Fischer-Speier Esterification. The major components of almost all natural flavors and odors are esters. These fragrant esters are formed by the Fischer Esterification reaction. Saponification is the
