Analysis and Properties of Bis-(p-chlorophenyl)methylcarbinol

Abstract

Increasing use of bis-(p-chIorophenyl)methyIcarbinol (DMC or Dimite) as a miticide has made it desirable to publish analytical procedures. The technical material may contain 4,4'-dichlorobenzophenone, the compound from which it is made, and 1,1bis-(p-chloropheny 1) ethylene, the dehydration product of bis-(p-chlompheny])methylcarbinol. For estimating the composition of mixtures with either one of these impurities, melting point-composition data are given. For mixtures which also contain the 2,4'-isomers, a quantitative dehydration to the
