Abstract
A method for producing a multibranched aliphatic ester including reacting a multibranched aliphatic alcohol with a multibranched aliphatic carboxylic acid in the absence of a solvent without a catalyst to obtain a multibranched aliphatic ester, and distilling the multibranched aliphatic ester to obtain a purified multibranched aliphatic ester, wherein at least one of the alcohol and the carboxylic acid is a Ccompound, and the obtained ester has a Hazen color number (APHA) of 1 to 30. Each of the multibranched aliphatic alcohol and the multibranched carboxylic acid has a tertiary carbon atom and/or a quaternary carbon atom in the molecule and in which the total number of the tertiary carbon atom and/or the quaternary carbon atom in the molecule is 2 or more. The method wherein the reaction is caused at 180 to 300° C. The method wherein a monohydric alcohol and a monovalent carboxylic acid are used.
