Abstract
In a process for continuous acetylation of polysaccharide, a pressure is to be established in a reactor chamber such that a boiling point of a reaction mixture corresponds to a desired reaction temperature and an exothermicity of the reaction is controlled by evaporative cooling.

A process for continuous acetylation of polysaccharide comprising metering the polysaccharide in fiber or powder form, directly and continuously into a reactor (3) or pre-mixed in pre-mixers (1) with acetic acid/added substances and then fed as a suspension into the reactor (3), wherein pressure in a reactor space is set such that a boiling point of a reaction mixture corresponds to a desired reaction temperature and any exotherm of the reaction is controlled via evaporative cooling.
