The Additive for the Bitumen on the Basis of the Modiﬁed Hydrolytic Lignin of the Organochlorine Wastes of the Chemical Industries
In the production of the epichlorohydrin from the propylene by means of the chlorination, as well as the other similar industries such as the manufacture of the vinyl chloride, chlorallylene, dichloroethane form a large number of the accessory chlorinated organic compounds (ChOCs). These are the monohlorpropen, dichloropropane, dichloropropene, trichloropropane and so on. Because of its toxicity the chlorinated organic compounds are not utilized by the microorganisms, so their disposal is the major technological and ecological problems. In order to improve the efﬁciency of the process the banding of the toxic chlororganic compounds by the lignin to obtain the modifying additive for the bitumen, possessing the increased compatibility of the lignin with the bitumen, the lignin is activated with the chlorine water and polysulphides.
