Abstract

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.
