Abstract
The aim of the study is to obtain superplasticizers based on pyrolysis products of the Ustyurt gas chemical complex. The chemical composition of heavy pyrolysis distillate was studied and analyzed, the qualitative and quantitative composition of samples of heavy pyrolysis oil was studied, and heavy pyrolysis oils were separated into fractions at different temperatures. The process of obtaining naphthalene, indene and phthalic anhydride based on the distillation of liquid and solid fractions of heavy pyrolysis products has been implemented, the quantitative and qualitative composition of resin samples and products of processing of their fractions has been determined. On the basis of the developed catalysts, superplasticizers, additives to cement, were obtained, their strength, the average density of cement particles, the effect of the amount of superplasticizers and the duration of their action on the properties of the material were studied. The influence of catalysts on the process of obtaining superplasticizers has been studied, the results of tests of cement with a synthesized superplasticizer have been studied. The structure of substances has been proven by the results of UV spectroscopy.
