Abstract
PURPOSE: To perpare the title compound having uniform ether group-distribution, easily and economically, by reacting a cellulose with an etherifying agent in the presence of an aqueous caustic alkali solution, a specific quaternary salt and an organic solvent which is immiscible with water and miscible with the etherifying agent.
CONSTITUTION: Cellulose of the formulaI(Gul is dehydrated glucose unit skeleton, C6H7O2; OR1 and OR2 are OH or ether group) is reacted with an etherifying agent such as alkyl halide, aralkyl halide. etc., in the presence of (A) an aqueous alkali solution containing 1W4 moles of caustic alkali and 1W10 moles of water per 1 mole of the OH group in the cellulose, (B) an orgainc solvent such as aliphatic hydrocarbon and aromatic hydrocarbon, and (C) a quaternary salt of the formula II(M is N or P; R3W6 are organic groups bonded to M through covalent bonds; X- is anion).
