colorless to yellow liquid용도
Methyl 4-Methoxyacetoacetate is a reactant in the formation of an abiotic poorphyrinogen in aqueous solution.제조 방법
The preparation method of a 4-methoxyl group methyl acetoacetate: add solvents tetrahydrofurane in a kettle. and pass into rare gas element, the temperature in the kettle arranging reactor is 15-25℃, industrial sodium hydride and metal alkaline compound is added under whipped state, add solvents tetrahydrofurane again, the mixed solution reaction 4-6h of methyl alcohol and 4-chloro methyl acetoacetate is dripped in less than 20℃, then be warming up to 20-25℃ and continue reaction 4-15h, TLC detection reaction is complete, reduce system temperature to 6-10℃, add the hydrochloric acid soln regulation system pH=5-7 that volumetric molar concentration is 2mol/L, stratification, after separatory, upper strata is concentrated is spin-dried for removing solvents tetrahydrofurane, then colorless product 4-methoxyl group methyl acetoacetate is obtained by wiped film molecular distillation.메틸4-메톡시아세톡시아세테이트 준비 용품 및 원자재
