METHOD OF OBTAINING HIGHER FATTY CHLORINATED ACIDS Russian patent published in 2014 - IPC C07C53/19 C07C51/215 C07C51/225 

FIELD: chemistry.

SUBSTANCE: invention relates to an improved method of obtaining higher fatty chlorinated acids of general formula R(CHCl)_nCOOH, where R is an aliphatic hydrocarbon radical, which contains 9-22 carbon atoms; n=1-4, by oxidation of chloroparaffins in the presence of a catalyst, which is mixed with chloroparaffins in the presence of air oxygen at a temperature of 120-125°C, and oxidation is carried out by air oxygen at a temperature of 105-110°C and atmospheric pressure for 30 h, characterised by the fact, that as the catalyst applied is a catalytic system, which consists of cobalt stearate and potassium stearate with the molar ratio of 1:0.5÷1.

EFFECT: possibility of obtaining higher fatty chlorinated acids of wide assortment, an increased rate of a reaction course and reduction of cobalt stearate quantity, partially replaced with potassium stearate.
