SYNTHESIS OF CATIONITE BASED ON INDENE, A SECONDARY PRODUCT OF HYDROCARBON PYROLYSIS
Abstract
In recent years, Uzbekistan’s chemical industry has been rapidly developing; however, the secondary products from pyrolysis processes remain underutilized. In particular, it has been found that the pyrolysis oil contains the aromatic hydrocarbon indene. According to the authors of the study, the proportion of indene in the oil obtained from continuous hydrocarbon pyrolysis is approximately 10% [1]. Indene is a compound containing a benzene ring, and it can be processed further to serve as a raw material in the synthesis of valuable products. Therefore, extracting indene from pyrolysis oil and using it to synthesize polymer ion-exchange materials - cationites, which are widely used in the chemical industry - is an important problem [2]. The aim of this work is to extract indene from the pyrolysis oil obtained at gas processing plants (such as an automobile gas processing plant) and to synthesize a cationite from it that functions in sulfuric acid, specifically the polymethyleneindenesulfonate cationite [3].
