Abstract: Provided is a method of producing fatty acid alkyl esters at high reaction efficiency, wherein the impurities inhibiting the reaction such as water are removed sufficiently. The fatty acid alkyl esters are produced efficiently, by a method of producing fatty acid alkyl esters, at least comprising (A) a step of removing at least water from an oil/fat raw material, (B) a step of converting the fatty acid glycerides contained in the oil/fat raw material into fatty acid alkyl esters and reducing the triglyceride content in the fatty acid alkyl esters obtained to 0.1 wt % or less by fine-particle dispersion and agitation, and (C) a step of separating at least glycerol from the mixture containing fatty acid alkyl esters.

Abstract: Disclosed are a metal processing lubricating oil composition and a process for producing the same. A metal processing lubricating oil composition according to this invention comprises mineral oil, synthetic oil or a mixture thereof, and phosphoric ester and orthophosphoric acid mixed and heated in the mineral oil, synthetic oil or mixture thereof. The lubricating oil composition gets rid of the tiresome pre-treatment associated with the conventional lubricating method, and exhibits a high seizure prevention performance in cold plastic working only by coating it on workpieces. The lubricating oil composition may further comprise metallic phosphate to suppress corrosivity against ferrous materials.
