A catalyst containing a quaternary ammonium salt represented by the following general formula (1) is used as a catalyst for dissociation of a blocking agent.
[In the formula, each of R1 to R3 represents an aliphatic hydrocarbon group having 1 to 8 carbon atoms or an aromatic hydrocarbon group having 6 to 14 carbon atoms; R4 represents an aliphatic hydrocarbon group having 9 to 20 carbon atoms; X represents at least one member selected from the group consisting of a phosphate group, a borate group, a hydrogencarbonate group, a monoalkylcarbonate group and a carbonate group; a is an integer in the range of 1 to 3; and b is an integer in the range of 1 to 3.]

quaternary ammonium compounds from various tertiary amines and the (environmentally friendly) alkylationagent dimethyl carbonate were carried out. The effects of reaction temperature, reaction time, material mol ratio and solvent dosage on quaternization were examined, and the optimum reaction conditions were determined. Under the optimum conditions, the conversions of mono‐alkyl tertiary amines could
