Beschreibung
Zusammenfassung:	FIELD: chemical technology. ^ SUBSTANCE: invention relates to a method for synthesis of halogenated paraffin. Method involves carrying out electrolysis of higher alpha-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. ^ 3 cl, 4 tbl, 16 ex
