METHOD OF PRODUCING AMINO ALCOHOL DIESTERS Russian patent published in 2011 - IPC C07C219/06 C07C219/08 C07C213/06 

FIELD: chemistry.

SUBSTANCE: obtained amino alcohol diesters are intermediate products in production of surfactants and antistatic agents for textile industry and household chemistry. The disclosed catalytic esterification method is realised in a mixture containing fatty acids, methyl diethanolamine or triethanolamine in the presence of a catalyst. The catalyst used is a platinum (II) based complex compound of formula H₂[Pt(CN)₄]^*3H₂O in amount of 0.05-0.1 wt % with respect to total weight of the product.

EFFECT: method enables to lower the effect of temperature on the process and shorten the esterification reaction time to obtain a high-quality product with high output.
