| 以氯代苯乙酮為原料,經Wolff-Kishner-黃鳴龍還原法合成2-氯代乙基苯。通過正交實驗考察了原料配比、反應時間等因素與2-氯代乙基苯收率的關系。產物通過紅外光譜表征,經比較,初步確定該反應的最佳工藝條件: 在120 ℃下氯代乙基苯與85 %水合肼的投料比為1 ∶7 (物質的量比) 時, 反應2 h ,2-氯代乙基苯的收率達到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 |
