Synthesis of Methyl Stearate The purpose of this lab was the convert liquid methyl oleate to solid methyl stearate by catalytic hydrogenation. Firstly‚ we produced hydrogen gas using solid mossy zinc and sulfuric acid. Using the hydrogen produced in the previous reaction‚ we were able to convert the liquid methyl oleate to solid crystals of methyl stearate. A mineral oil was also used to bubbler was used to maintain the hydrogen pressure slightly above the atmospheric pressure and to prevent back-diffusion

Grignard reaction Abstract: In this laboratory‚ triphenylmethanol was synthesised from reacting benzophenone and bromobenzene using Grignard reaction. As the reaction was to set up to produce a Grignard reagent and then recrystallize it to obtain pure sample. The percentage yield obtained was 55% and its melting point was 161 co which is within the literature value 160-163 co. In addition to that the IR spectroscopy confirmed the molecule structure to be triphenylmethanol. Introduction: The Grignard

Purpose of this experiment is to synthesis Banana oil by mixture of the isopentyl alcohol and acetic acid . Banana oil smells like fruit mostly it smells like banana. This reasons that this compound uses in different perfume products as well as the gums for the flavor. The reaction that takes place in this experiment is a esterification. In this experiment‚ the carboxyl group of the acetic acid joins with the hydroxyl group of the isopently alcohol‚ catalyzed by the presence of sulfuric acid
