NEW MATERIAL: A compound of formula [A is 7-28C aliphatic hydrocarbon chain; (n) is 0-2; F1, F2 are each 1-20C aliphatic hydrocarbon, or aliphatic hydrocarbon in which (m) is 1-4, and R is a 1-30C group of formula -(CH2)m-(CO)-O-R, for forming dicarboxylic acid ester derivative].
EXAMPLE: 1,2-Tetradecane-dioleate.
USE: A fat substitute which is eatable as food and medicine, and preferably which can be partially digested. No side reaction and low calorie.
PROCESS: An ester compound is obtained by the conventional esterifying reaction of a diols, and fatty acid, acid chloride or acid anhydride. The fatty acid diester extended by dicarboxylic acid ester, is obtained by reacting an addition product of the fatty acid alcohol obtained by reacting aliphatic alcohol or aliphatic alcohol derivative with dicarboxylic acid, and dicarboxylic acid, with diols.
