The Production of Methyl colza oil acid ester

Methyl colza oil acid ester  is a type of light yellow oil liquid with the saponification value 180-195mgKOH/g and the  iodine value 100-115gI2/100g(MAX).  Methyl colza oil acid is widely used in auxiliary for light textile .
Methyl colza oil acid esterThe mefatty acid thyl esters  production of the classic method is based on the triglyceride ester exchange of the methyl ester. Sodium hydroxide dissolved in methanol as a catalyst. The purpose of this work is to check, especially calcium compounds, heterogeneous catalyst to produce methyl esters.This study shows that rapeseed oil transesterification the catalytic éectively alkaline earth metal compounds:? Calcium oxide, methanol and barium hydroxide. Calcium catalysts, due to its weak solubility in the reaction medium, less than the sodium hydroxide positive. However, the calcium catalyst is cheap, resulting in the number of stages of technology to reduce the amount of unnecessary waste products.  It was found that the transesterification reaction rate by ultrasound and by the introduction of appropriate reagents reactor in order to promote the enhanced solubility of methanol in the rapeseed oil.
