COMPOSITION OF WATER SOLUBLE METAL WORKING FLUIDS FROM FATTY ACID METHYL ESTER & BYPRODUCTS RECOVERED FROM EVAPORATION RESIDUE RECOVERED FROM BIO-DIESEL PRODUCTION

摘要

PURPOSE: A water-soluble metal processing oil composition is provided to obtain excellent biodegradation property, reduce the toxicity or the ecological toxicity, and use the by-product which is not distilled with the fatty acid methyl ester. CONSTITUTION: The water-soluble metal processing oil composition includes: the fatty acid methyl ester obtained from the residue which becomes in the biodiesel production; the lubricating base oil 5 ~ 80 parts by weight by-product; a mixture adding the additive 5 ~ 70 parts by weight in the ion exchanged water 0 ~ 70 parts by weight. The fatty acid methyl ester and by-product are the by-product not distilled with the fatty acid methyl ester created after producing the rape oil, soybean oil, palm oil, jatropha existence, sunflower oil, the biodiesel fuel oil.
