Preparation of o 3 formylmethoxy 2 hydroxypropylcellulose






Chemical Papers 39(3): 407-412

Preparation of o 3 formylmethoxy 2 hydroxypropylcellulose

O-[3-(2,2-Dimethoxyethoxy)-2-hydroxypropyl]cellulose was prepared by the reaction of bead O-(3-chloro-2-hydroxypropyl)cellulose with sodium 2,2-dimethoxyethoxide in dioxan. On partial acid hydrolysis this derivative afforded O-(3-formylmethoxy-2-hydroxypropyl)cellulose. Under the conditions of alkylation partial crosslinking of cellulose by transverse 2-hydroxy-1,3-propylene bonds took place. The prepared new aldehyde derivative of bead cellulose retained the spheric shape of the particles.
