摘要
以氯代特戊酰氯、硫酸羟胺和邻氯氯苄为主要原料合成高效除草剂异噁草酮。采用过饱和的氢氧化钠浆料,提高了反应速度和异噁草酮的收率。反应总收率≥84%。
The clomazone was synthesized with 3-chloro-2,2-dimethyl propionyl chloride hydroxylamine sulfate and ortho-chlorobenzyl chloride as the raw materials. The yield was improved, and configuration transformation was limited when sodium hydroxide was used as high concentration slurry. The total yield was over 84%.
