Abstract
The present invention relates to N acyl and O acyl derivatives of N,N-bis(2,2-dimethyl-3-hydroxypropyl)amine which are produced as follows: ammonium halide, sulphate or aldehyde, and isobutyl aldehyde are subjected to condensation reaction and the obtained product is reduced to the corresponding amino alcohol. The hydrogen atoms linked to the nitrogen atom and the oxygen atom are thereafter substituted by acyl groups. The N-acylation and esterification of hydroxyl groups can be performed simultaneously using a carboxyl acid, carboxyl acid halide, or carboxyl acid anhydride. The N,N-bis(2,2-dimethyl-3-hydroxypropyl)amine derivatives can be used as polymer stabilizers, PCV plasticizers, emulsifiers, corrosion resistance agents, and metal complexing agents.
