METHODS OF STABILISING ORGANOCHLORINE SOLVENTS (VERSIONS) Russian patent published in 2011 - IPC C07C17/42 C07B63/04 C07C21/04 C07C21/10 C07C19/45 C07C19/04 

FIELD: chemistry.

SUBSTANCE: invention relates to a method of stabilising organochlorine solvents selected from perchloroethylene, trichloroethylene, dichloroethylene and chloroform, in which the stabiliser is used in amount of 0.01-1.0% of the weight of the stabilised organochlorine solvent. The stabiliser used is epoxidated soya bean oil, or a stabilising system consisting of 95.55-98.90 wt % epoxidated soya bean oil, 0.10-0.40 wt % urotropin, 1.00-4.00 wt % ethanol and 0.00-0.10 wt % epichlorohydrin, or a stabilising system consisting of 50.0-96.0 wt % epoxidated soya bean oil and 4.0-50.0 wt % ethanol.

EFFECT: highly efficient stabilisation of organochlorine solvents, availability and low cost of stabiliser components and relatively low environmental hazard.
