NOMENCLATURE:-
Common name dicofol (BSI, E-ISO, (m) F-ISO, ESA); kelthane (JMAF); no name (Germany)
IUPAC name 2,2,2-trichloro-1,1-bis(4-chlorophenyl)ethanol
Chemical Abstracts name 4-chloro-a-(4-chlorophenyl)-a-(trichloromethyl)benzenemethanol
CAS RN [115-32-2] EEC no. 204-082-0 Development codes FW-293 (Rohm & Haas) Official codes ENT 23 648

PHYSICAL CHEMISTRY:-
Composition Tech. is 95% pure, composed of 80% dicofol and 20% its -1-(2-chlorophenyl)-1-(4-chlorophenyl)- isomer ('o,p'-dicofol'). Mol. wt. 370.5 M.f. C14H9Cl5O Form Colourless solid; (tech. is a brown, viscous oil). M.p. 78.5-79.5 A C B.p. 193 A C/360 mmHg (tech.) V.p. 0.053 mPa (tech.) KOW logP = 4.30 S.g./density 1.45 (25 A C; tech.) Solubility In water 0.8 mg/l (25 A C). In acetone, ethyl acetate, toluene 400, methanol 36, hexane, isopropanol 30 (all in g/l, 25 A C). Stability Stable to acids, but unstable in alkaline media, being hydrolysed to 4,4'-dichlorobenzophenone and chloroform; DT50 (pH 5) 85 d, (pH 7) 64-99 h, (pH 9) 26 min. The 2,4'-isomer is hydrolysed more rapidly. Degraded by light to 4,4'-dichlorobenzophenone. Stable AL80 A C. WP formulations are sensitive to solvents and surfactants, and these may affect acaricidal activity and phytotoxicity. F.p. 193 A C (open cup).
