METHOD OF PRODUCING OLIGOMERIC BORIC ACID ESTERS

FIELD: organoelemental compounds. SUBSTANCE: process is accomplished by interaction of alkylene oxides and C1-C4-alcohols in presence of 0.02-0.5 wt % of alkali metal alcoholate followed by treating alkaline polymerizate obtained with boric acid and evacuation. Process is distinguished by preliminar...

Beschreibung
Zusammenfassung:	FIELD: organoelemental compounds. SUBSTANCE: process is accomplished by interaction of alkylene oxides and C1-C4-alcohols in presence of 0.02-0.5 wt % of alkali metal alcoholate followed by treating alkaline polymerizate obtained with boric acid and evacuation. Process is distinguished by preliminarily distilling away 10-30% of alkaline polymerizate and treating with boric acid still residue with boiling range 225-265 C and density 1.05-1.06 g/cu.cm. EFFECT: simplified process and reduced expenses. 3 cl, 4 ex
