Process for obtaining a mixture of methyl esters of the fatty acids from fats used as a biodiesel

摘要

The invention relates to the technological processes for obtaining alternative sources of ecologically pure combustible Summary of the process consists in that it is carried out the transesterification of glycerides at heating up to 40 degree C with methyl alcohol taken in stoichiometric ratio, catalyzed with potassium hydroxide in the ratio of 1,3...1,8 mass % about the substrate. Then it is separated the methyl esters upper layer and it is carried out the neutralization of the catalyst residue by sparging with carbon dioxide up to the attainment of pH = 6,25...6,75 Claims: 1
