Abstract
염소치환 anisol과 chloral hydrate를 축합하면 D.D.T 류의 합성에서와 같이 bis compound의 화합물이 생성될 것이고 D.D.T 계통의 화합물처럼 살충능이 있으리라고 예측되므로 4-chloro anisol 과 chloral hydrate를 축합하여 싱생물의 구조를 검사하였던 바 2,2 bis(2-methoxy-5-chlorophenyl) 1.1.1-trichloroethane임을 확인하였으며 반응조건과 「국화꼬마수염진딧물」 및 「귤응애」에 대한 살충능을 검사한 결과 前報文에서 발표한 바 있는 화합물들의 살충능에 비하여 5배나 강한 살충능을 가졌다는 사실을 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℃ The insecticidal effects of M.C.T against the Citrus Red Mite and Chrysanthemum Aphid were five times as strong as D.D.T.
