Abstract

It is shown that the alkali-catalysed methanolysis step of an official method for determination of long-chain marine oil fatty acids produced dimethyl and mixed alcohol esters from the plasticizer dioctyl [actually di(2-ethylhexyl)] phthalate. An independent boron trifluoride-catalysed methanolysis step produced a lower level of artifacts but the official two-step process gave an even higher conversion figure than either catalyst independently. The retention times for the dimethyl, mixed alcohol, and dioctyl phthalates are discussed in relation to methyl esters of common fatty acids on polyglycol wall-coated open-tubular gas-liquid chromatographic columns.
