| titleOfInvention | Process for producing alkyl etherified cellulose and derivatives thereof |
| abstract | PROBLEM TO BE SOLVED: To provide a method for producing an alkyl etherified cellulose (derivative) with little coloring. SOLUTION: A cellulose (derivative) (A) and an alkylating agent (B) are mixed with an alkali (C) and a quaternary ammonium salt phase transfer catalyst (D) having a total amine value of 0.5 mgKOH / g or less. A method for producing an alkyl etherified cellulose (derivative) (E), wherein the reaction is carried out in the presence of three substituents constituting the cation of (D) above having a carbon number of 1 to 22 A linear or branched aliphatic hydrocarbon group having 8 to 22 carbon atoms, or an arylalkyl or arylalkenyl having 7 to 22 carbon atoms, which is a chain or branched aliphatic hydrocarbon group It is preferable that the anion of (D) is a monovalent anion obtained by removing one proton from a protonic acid. [Selection figure] None |
