Abstract
Abstract The Michael type addition reaction of cellulose with a series of vinyl sulfoxides, namely methyl vinyl sulfoxide, ethyl vinyl sulfoxide, t-butyl vinyl sulfoxide, and phenyl vinyl sulfoxide, was performed with NaOH as a catalyst to produce 2-(alkyl- or arylsulfinyl)ethyl cellulose derivatives. The high permselectivity of sulfur dioxide against nitrogen and oxygen was achieved through these sulfoxide modified cellulose membranes.
