13220-33-2  Manufacturer High Purity1-Methyl-3-pyrrolidinol

It is obtained by chlorination and cyclization of 1,2, 4-butanetriol. 1. Chlorination Add butanetriol and glacial acetic acid into the reaction pot, stir and heat to about 100 ℃, pass in dry hydrogen chloride gas, and react at 90-100 ℃ for 30h. When a large amount of hydrogen chloride begins to appear in the tail gas, check the end point of the reaction and stop passing hydrogen chloride. After cooling, discharge, wash with saturated sodium carbonate solution, carry out vacuum distillation, collect 120-135 ℃(12.7-13.3kPa) fraction, that is, 1, 4-dichloro-2-butanol, as oil, yield 50-60%. 2. Cyclization Add 1, 4-dichloro-2-butanol and methylamine aqueous solution into a cyclizing pot, heat to 120 ℃ in a closed manner, and stir for 10h. Cool, add solid sodium hydroxide, and filter out the precipitated inorganic salt. The oil layer is divided into reduced pressure distillation, and the 76-85 ℃(2.13kPa) fraction is collected, which is the finished product. Extraction of the water layer with benzene can also obtain a part of 1-methyl-3-pyrrolidone alcohol. The yield is about 60%. Each ton of product (content 80-90%) consumes 1,4-dichloro-2-butanol (90%) about 2330kg and monomethylamine (30%)5200kg.
