use | methoxyacetyl chloride is an intermediate of fungicides evil cream and metalaxyl. Used as an intermediate in medicine and dyes |
production method | its preparation method is to put methanol and flake NaOH into the reaction flask, reflux reaction for 30min, then cool and add a certain amount of chloroacetic acid, heat up the reaction for 2h, evaporate methanol after reflux, then azeotropic dehydration, and cool to below 10 ℃ after water is completely removed, toluene and SOCl2 were added as acylating agents, reacted at about 45 ℃ for 1h, cooled to 20 ℃, and distilled to obtain the product after post-treatment.
