A method for synthesizing N,N-dimethylformamide dimethyl acetal, comprising the steps of (1) heating N,N-dimethylformamide to 70°C, mixing with dimethyl sulfate in a molar ratio of 1:1 and reacting for 4 hours after the end of dropwise addition to obtain the imine complex, and then cooling to room temperature; (2) adding solid sodium methanol to 200 solvent oil, dispersing it by ultrasonication, adjusting the temperature to 25 ℃ and maintained, dropwise addition of the imine complex, the reaction for 2 hours and then filtered, the filtrate often pressure fractionation, collection of 105-108 ℃ fraction, to obtain N,N-dimethylformamide dimethyl acetal, the yield was 75.3%, purity of 97%; wherein the molar ratio of sodium methanol to the imine complex is 1:1. The synthesis of the N,N-dimethylformamide dimethyl acetal of Example 6 is the same as that of Example 2, the The difference is that the organic solvent of this embodiment is a mixed solvent oil: D40 solvent oil, D60 solvent oil and 260 solvent oil, with a volume ratio of 2:1:1, to obtain N,N-dimethylformamide dimethyl acetal with a yield of 85.4% and a purity of 97%. | [References]
