초록

鹽素置換 anisol과 chloral hydrate를 縮合하면 D.D.T 類의 合成에서와 같이 bis compound의 化合物이 生成될 것이고 D.D.T 系統의 化合物처럼 殺蟲能이 있으리라고 豫測되므로 4-chloro anisol 과 chloral hydrate를 縮合하여 生成物의 構造를 檢討하였던 바 2,2 bis(2-methoxy-5-chlorophenyl) 1.1.1-trichloroethane임을 確認하였으며 反應條件과 「국화꼬마수염진딧물」 및 「귤응애」에 대한 殺충能을 檢討한 結果 前報文$^{(67)}$에서 發表한 바 있는 化合物들의 殺蟲能에 比하여 5培나 强한 殺蟲能을 가졌다는 事實을 알았다.

An insecticide was obtained by condensation of chloral hydrate with p-chloroanisole. The structure of the insecticide was found to be 2,2-bis(2-methoxy-5-chlorophenyl)1,1,1-trichloroethane(M.C.T.). The best conditions for this condensation reaction were as follows: 1) The sulfuric acid concentration: 93% 2) The mole ratio of sulfuric acid to p-chloroanisole: 8 3) The mole ratio of chloral hydrate to p-chloroanisole: 0.7 4) The reaction time and reaction temperature: 12 hrs and 25-30$^{\circ}C$ The insecticidal effects of M.C.T against the Citrus Red Mite and Chrysanthemum Aphid were five times as strong as D.D.T.
