ABSTRACT This invention is directed to a process for the separation and/or purification of oligo and polyhydroxy compounds. This is accomplished by introducing and subsequently eliminating protective groups. Oligo and polyhydroxy compounds are reacted with bis-(ethyl- pivaloyloxy)-diboroxane or ethylboroxin, optionally in inert solvents, the resulting O-ethylboranodiyl derivatives of the hydroxy compounds are separated off and the O-ethylboranodiyl protective groups are eliminated by alcoholic compounds, for example methanol or glycol.
