METHOD FOR STABILIZATION OF CHLORINATED HYDROCARBONS Russian patent published in 2004 - IPC

FIELD: technology of organic synthesis.

SUBSTANCE: invention relates to a method for stabilization of chlorinated hydrocarbons. Stabilization of liquid chlorinated hydrocarbons of fraction C₁₄-C₃₂ with the chlorine content 24-55 wt.-% is carried out by addition of stabilizing mixture taken in the amount 10 wt.-% of chlorinated hydrocarbons to be stabilized. Stabilizing system comprises epoxy-diane resin, 2,6-di-tert.-butyl-4-methylphenol, hexamethylenetetramine and chlorinated hydrocarbons of fraction C₁₄-C₃₂ in the following ratio of components, wt.-%: epoxy-diane resin (sort ED-20, ED-16) : 2,6-di-tert.-butyl-4-methylphenol (ionol) : hexamethylenetetramine of fraction C₁₄-C₃₂ (urotropin) = (10-20):(0-3): (0-0.02):(80-90), respectively. Method provides enhancing stability of goods product, prevention of equipment corrosion caused by hydrogen chloride.

EFFECT: improved stabilizing method.
