METHOD FOR PREPARING HALOGENATED PARAFFIN BASED ON HIGHER ALPHA-OLEFINS Russian patent published in 2006 - IPC C07C17/08 C07C19/01 C25B3/06 

FIELD: chemical technology.

SUBSTANCE: invention relates to a method for synthesis of halogenated paraffin. Method involves carrying out electrolysis of higher α-olefins of (C₁₆-C₂₈)-fractions and higher in the presence of hydrohalogenic acid solution (hydrochloric or hydrobromic acid) and its corresponding salt (sodium or potassium). Process is carried out in diaphragm-free electrolyzer by using graphite or platinum, or titanium, or oxide-ruthenium-titanium, or glass-carbon cathode and graphite or platinum, or oxide-ruthenium-titanium, or glass-carbon anode at temperature 20-90°C and current anode density 100-1400 A/m² and in the mole ratio acid : salt : olefin = (2-14.2):(0-3.5):1, respectively. Invention provides synthesis of chloroparaffins with chlorine content 21-50%.

EFFECT: improved method of synthesis.
