PROCESS FOR PREPARING PLASTICIZER Russian patent published in 1996 - IPC

Abstract RU 2054013 C1

FIELD: organic chemistry. SUBSTANCE: plasticizer is prepared by reacting wood resinous inhibitor resulting from heat treatment of wood with olefin oxide at weight ratio from 1.0 to (1.1-2.0), respectively. The reaction is carried out in the presence of potassium or sodium hydroxide in nitrogen atmosphere at 130-160 C. The resulting oxyalkylated compound is reacted with carboxylic acid anhydride at 90-120 C. EFFECT: more efficiency preparation process. 7 cl, 2 tbl
