Reaksi epoksidasi mengubah ikatan rangkap pada senyawa olefin menjadi epoksida atau oksiran. Metil ester dari minyak nabati dengan kandungan asam lemak tak jenuh dapat digunakan sebagai bahan baku reaksi epoksidasi. Epoksida berbasis memiliki potensi yang besar untuk plasticizer pemrosesan polimer. Pada penelitian ini, dilakukan secara in-situ menggunakan asetat, hidrogen peroksida, dan sulfat ...

This study investigates the influence of some chemical additives such as methanol, ethanol, sodium oleat, chloroform and sodium hexametaphosphate (SHMP) on the dry fine grinding of calcite (X50= 33 µm) using a stirred media mill. The experiments were carried out by a batch operation, and the change in colour properties (Ry, whiteness and yellowness) of calcite powder. The results showed that th...

Metode penelitian adalah deskriptif yang bertujuan untuk mengetahui profil gliserida dan identifikasi komposisi asam lemak pada minyak ikan patin. Minyak patin diperoleh menggunakan proses rendering kering (dry rendering). Analisis dengan kromatografi gas (GC) sebelumnya diesterifikasi BF3. Total jenuh sebesar 49,344%, total tak 54,524% terdiri dari MUFA 39,101% PUFA 15,423%. Ditemukan omega 3...

glycerol mono-oleate (gmo) was produced by direct esterification reaction with amberlyst 16 resin catalysts with the efficiency of 86% and was used as a surfactant for synthesis of cofe2o4 nano-particles by surfactant-assisted microwave method. fourier transform infrared spectroscopy (ft-ir), x-ray diffraction (xrd) and scanning electron microscopy (sem) were used to consider the structural and...
