Abstract
A process for the manufacture of methylcellulose or methylhydroxyalkylcellulose by the reaction of alkaline cellulose with an excess of liquid methyl chloride or a mixture of liquid methyl chloride and liquid alcoholic oxide in the presence of dimethyl ether likewise liquid, at elevated temperatures and using a tube of reaction, characterized in that the components of the reaction and dimethyl ether are fed continuously to the reaction tube, are placed immediately after entering the reaction tube at temperatures between 70 and 95º C, maintaining such temperature constant, until the end of the reaction tube, after which the reaction mixture is extracted continuously and the cellulose ether is isolated.
