METHOD OF PREPARING OF A MIXTURE OF POLYALKYLENE ESTERS Russian patent published in 1995 - IPC

FIELD: organic chemistry. SUBSTANCE: method involves interaction of ethylene oxide with butadiene-1,3 monoepoxyde in the presence of basic catalyst. Butadiene-1,3 oxide is treated with water in the presence of anion-exchange resin in HCO₃-form at the molar ratio H₂O:monoepoxyde:active group of anion-exchange resin = (10-20):1:(0.15-0.30) at 60-80 C at uniform dosing of monoepoxyde to reaction mass, anionite separation and water evaporation. Alkaline metal monoglycolate is used as a catalyst, and process is carried out at 120-150 C at molar ratio initial butadiene monoepoxyde: ethylene oxide:catalyst = 1:(10-55):(0.15-0.75). EFFECT: improved method of mixture preparing. 1 tbl
