Abstract
An efficient dehalogenation can be carried out by a method which comprises treating an organic compound containing a compound of halogen, such as fluorine or chlorine, as an impurity and having non-conjugated carbon-carbon double bonds, for example, butene polymer produced with a boron trifluoride catalyst, with an inorganic solid treating agent containing aluminum atoms. When the dehalogenation is conducted in the presence of a basic substance such as ammonia or an amine, it can be continued over long while inhibiting the isomerization of the non-conjugated carbon-carbon double bonds.
