Side reactions during the vinyl sulfonation of cellulose: Side reactions during the vinyl sulfonation of cellulose. Dimov, Kiril; Simeonov, N. (Inst. Chem. Technol., Sofia, Bulg.). Chem. Vlakna, 27(1), 25-30 (German) 1977. CODEN: CMVLA8. DOCUMENT TYPE: Journal CA Section: 43 (Cellulose, Lignin, Paper, and Other Wood Products) Evolution of the effect of temp., Na vinylsulfonate (I) [3039-83-6] concn., reaction time, and NaOH and Na benzoate [532-32-1] concn. on the formation of by-products in the vinylsulfonation of cellulose [9004-34-6] showed all the parameters influenced the reaction to a certain extent. Optimum conditions for the vinsulfonation of cellulose were: temp. 70.degree., reaction time 300 min, I concn. 60.4%, and NaOH concn. 50 g/L.
