Abstract:  Rate constants of dehydrochlorination of 2,3,4-trichloro-l-butene and 2,3,3-trichloro-1-butene by methanolic solution of sodium hydroxide at temperatures 0 —60°C were measured and the appropriate activation energies were calculated. The results showed that the reaction rate of dehydrochlorination of 2,3,4-trichloro-l-butene was at 40°C 436 times greater than that of 2,3,3-trichloro-1-butene. The activation energy for the first reaction was 17 ± 0.5kcal mol-1, the frequency factor A2,3,4-тсв = 1.014 X 1011 ± 1.33 X 109 1 mol-1 s-1 and that for the second reaction was 20 + 1.2 kcal mol-1 , the frequency factor was A2,3,3-тсв = 4.094 X 1010 ± 1.75 x 109 1 mol-1 s-1.
