Pengaruh Variasi Konsentrasi Katalis Asam Sulfat Pekat Terhadap Hasil Derajat Esterifikasi Metil Laurat

Abstract

Fatty acid esters are derived from vegetable oils and animal fats which can be used for chemical industries, such as the cosmetics industry, pharmaceutical ingredients, and the manufacture of fat alcohol, one of which is methyl laurate. This study aims to determine the effect of variations in concentrated sulfuric acid catalysts on the results of the degree of esterification can provide significant results in order to obtain an optimal degree of esterification. This research is an experiment which is to determine the effect of the addition of variations in concentrations of concentrated sulfuric acid catalyst to the results of the degree of esterification of methyl laurate. The research design used was a completely randomized design (CRD) of one factor, namely the effect of adding concentrated sulfuric acid catalyst. The variables observed were variations in the addition of concentrated sulfuric acid catalysts with a concentration of 2%, 3%, 4%, 5%, 6% to the results of the degree of esterification reacted for 3.5 hours. Analysis of statistical data obtained was tested using the Kruskal Wallis test. The results showed that the more concentrated concentrated sulfuric acid catalyst was added, the higher the degree of esterification. The results of the degree of esterification obtained are 99,25%. Statistical data analysis obtained sig value 0.009 (p<0,05) which means that the variation in concentrated concentrations of concentrated sulfuric acid affects the results of the degree of esterification of methyl laurate.
