Abstract
The preparation of partially cyanoethylated cotton with acrylonitrile in the presence of sodium hydroxide is described, including effects of changes in time, temperature, and concentration of reagents. Products with retention of the fibrous form have been ob tained with degrees of substitution up to 2.7 cyanoethyl groups per anhydroglucose unit.
Hydrolysis of the cyanoethyl group occurs readily under alkaline conditions and re sults in both cleavage and conversion to the carboxyethyl group. Maximum conversion in the latter case was 29%.
