Annotation
The process for obtaining naphthalene, indene, and phthalic anhydride through the distillation of liquid and solid fractions of heavy pyrolysis products has been implemented. The quantitative and qualitative composition of resin samples and the products derived from their fractions have been determined. Additionally, superplasticizer additives for cement were developed, and their strength, average particle density of the cement, the impact of the amount of superplasticizers, and their duration of action on the material properties were studied.
