Abstract

1381033 Isomerization of meso- and dl- 1,2,3,4-tetrachlorobutane BP CHEMICALS INTERNATIONAL Ltd 5 July 1973 [23 Aug 1972] 39350/72 Heading C2C Meso - 1,2,3,4 - tetrachlorobutane is isomerized to dl-1,2,3,4-tetrachlorobutane and vice-versa by contacting in the liquid phase the compound to be isomerized with an anhydrous AlCl 3 catalyst. Preferably 0À1 to 20% by weight of catalyst is present based on the total composition weight and isomerization is carried out at 80‹ to 120‹ C.
