| 以氯代苯乙酮为原料，经Wolff-Kishner-黄鸣龙还原法合成2-氯代乙基苯。通过正交实验考察了原料配比、反应时间等因素与2-氯代乙基苯收率的关系。产物通过红外光谱表征，经比较，初步确定该反应的最佳工艺条件： 在120 ℃下氯代乙基苯与85 %水合肼的投料比为1 ∶7 (物质的量比) 时, 反应2 h ,2-氯代乙基苯的收率达到90.1 % 。 |

2 - chloro-ethyl benzene was synthesized by chlorinated acetophenone via Wolff-Kishner-Huangminglong reduction. the relationship between raw material ratio and reaction time and 2 - chloro-ethyl benzene yield was Investigated by orthogonal test. products were characterized by FT-IR, and the best optimum conditions was at 120 ℃ and the ratio 85% chloro-ethylbenzene feed and hydrazine was at 1: 7 (molar ratio), the reaction of 2 h and the yield of 2 - chloro-ethyl benzene was 90.1%. of and relationship. Products by IR spectroscopy, by comparison, the initial reaction to determine the |
