Hexanes, hexachloro

Photolytic. Photolysis of thin films of solid endrin using UV light X = 254 nm) produced 5-ketoendrin and endrin aldehyde and other compounds (Rosen et al., 1966). When exposed to sunlight for 17 d, endrin completely isomerized to 5-ketoendrin (1,8 eYO-9,10,11,11-hexachloro-yclo[6.2.1.1 .0 0 °]dodecan-5-one) and minor amounts of endrin aldehyde (Burton and Pollard, 1974). Irradiation of endrin by UV light X = 253.7 and 300 nm) or by natural sunlight in cyclohexane and hexane solution resulted in an 80% yield of l,8-eA o-9,ll,ll-pentachloro-cyclo[6.2.1.1 0 0 °]dodecan-5-one (Zabik et al, 1971). This compound also formed from the sunlight photolysis of endrin in hexane solution (Fujita et al., 1969). 

The recovery of chlorobenzenes (di- to hexachloro) and hexachlorocyclo-hexane (HCH) isomers from supercritical carbon dioxide by trapping in cold solvent was studied (Wenclawiak et al., 1994).
