    摘要: For the oligomerization of a fatty ester or fatty acid containing conjugated double bonds, the reaction uses a catalyst consisting of an activated earth, e.g., montmorillonite, at a temperature of from 100.degree.-180.degree. C., preferably from 130.degree.-160.degree. C. The process can be carried out continuously or in a batch process on a fixed bed and is particularly applicable to conjugated methyl esters obtained by conjugating and transesterifying sunflower seed oil. The oligomerized products obtained are particularly useful as lubricants or polycondensation reactants.

    摘要: Dialkyl malonate/alkyl acrylate Michael addition product mixtures having at least three acceptor moieties in a substantial number of the molecules can be consistently prepared without the need for long reaction times or the use of a large excess of the acceptor when the reaction is effected by gradually adding one molar proportion of a dialkyl malonate to at least three molar proportions of an alkyl acrylate which has been preheated to 60.degree.-80.degree. C. in admixture with an initiator and a phase transfer catalyst. In a preferred embodiment, the preheated mixture is maintained at 60.degree.-80.degree. C. for at least one hour before the dialkyl malonate is added in order to increase the percentage of product composed of the heavier components.
