MOAM - Preparation Method
Open Data Verified Data
The methoxylation reaction was carried out in methanol using methyl chloroacetate and sodium methoxide as raw materials. After the completion of the reaction, the salt is separated by filtration, and the solvent is removed by distillation, and then the finished product is obtained by distillation under reduced pressure.

| purpose | used as intermediate in medicine, pesticide and dye, intermediate in medicine for synthesis of vitamin B6 pharmaceutical synthesis, mainly used for the synthesis of week-effect sulfanilamide, vitamin B6, etc. |
| production method | from methyl chloroacetate and sodium methoxide by methoxylation reaction. Sodium methoxide was added to the reaction pot, and methyl chloroacetate was added with stirring. The temperature was initially controlled at about 30 ° C., and the reaction was continued at about 70 ° C. Thereafter. Temperature is too high affect the quality of the finished color; Temperature is too low, the reaction rate is too slow. After completion of feeding, pH value shall be measured at the later stage of reaction. If pH value is less than 9, sodium methoxide shall be added for adjustment and heat preservation shall be continued until the end of reaction. The reaction product was distilled off methyl methoxyacetate in The desalting pan, while the sodium chloride formed by the reaction remained in the desalting pan. |
