Process for producing silylated cellulose and silylated cellulose fiber, regenerated cellulose fiber obtained by the production method thereof, and fiber-reinforced plastic molded product incorporating them

摘要

PROBLEM TO BE SOLVED: To provide a method with which a silylated cellulose can be produced under more moderate reaction conditions.SOLUTION: A method of producing a silylated cellulose includes reacting a pre-processed cellulose, an acid catalyst, and a silylating agent that is, for example, represented by formula (1) at 0-55°C and 0.08-0.11 MPa. (Rto Rare the same or different and are C1-4 lower alkyl groups, C1-4 lower alkenyl groups, or an aryl group; and Ris H)
