Use | M-methyl anisole has been used to study the functionalized core of theophylline type a alkaloids. mainly used in organic synthesis mainly used in the synthesis of dyes and pharmaceutical intermediates |
production method | 1???? The reaction of m-cresol with methyl chloride in the presence of caustic is generally employed. Since methyl chloride is a gas, the reaction is difficult to operate. In this method, dimethyl sulfate was used as the alkylating agent, under alkaline conditions, the use of phase transfer catalyst, m-cresol into ether. 2. Methanol alkylation method????? Aluminum silicate catalyst was used, in which the content of Al2O3 was 20% ~ 80%; The reaction temperature was 5~10 ℃ higher than the boiling point of m-cresol; The ratio of ingredients to m-cresol: methanol = 1:(0.5~0.7)(Molar ratio). |
