Title: Prodn. of oligo:glycerol mixts. - by condensing glycerol in presence of boron cpd. and continually removing water formed
Inventor: HEES UDO DR
IPC: C07C41/09
Filed: 1991-05-24
Abstract: Prodn. of oligoglycerol mixts. is effected by condensing glycerol in the presence of a B cpd. while continuously removing the H20 formed.
