Title: Tetramethylguanidine Catalyzed Transesterification Of Fats And Oils: A New Method For Rapid Determination Of Their Composition
Author: Schuchardt U.
Lopes O.C.
Abstract: A new method for the rapid preparation of methyl esters from vegetable oils and fats, using tetramethylguanidine as catalyst, has been developed. This method is compared with the traditional method (Ce 2-66, using 20% BF3 in methanol) and that proposed by Hartman and Lago (using NH4Cl/H2SO4 in methanol). It is shown that the new method produces the methyl esters in quantitative yields and has certain advantages, as it is simpler, cheaper and does not result in isomerization of the fatty acids. © 1988 AOCS Press.
