Abstract
Esters of tertiaryaminopolyhydric alcohols are prepared by reacting a tertiaryaminopolyhydric alcohol with an ester of a mono or polyhydric alcohol with a straight chain aliphatic carboxylic acid having at least eight carbon atoms, in the presence of an alkali metal alkoxide catalyst. The displaced alcohol may be removed by volatilization if desired, under vacuum. In the examples: (1) ethyl oleate is added to sodium dissolved in triethanolamine and the mixture heated. A mutual solvent such as triethanolaminemonooleic ester may be added; (2) sodium dissolved in triethanolamine is heated with dry castor oil to give triethanolaminemonoricinoleic ester and glycerolmonoricinolein. Other tertiary amino polyhydric alcohols which may be employed are methyldiethanolamine, triisopropanolamine, phenyldiethanolamine and N-tertiary-dihydroxypropylamine. According to the Provisional Specification any carboxylic ester may be used, e.g. methyl acetate, dibutyl phthalate, dimethyl adipate and methyl benzoate.
