| description | In subsequent years the construction industry in our country is developing very rapidly. Accordingly, the requirements for the rational and efficient use of raw materials and energy resources in building materials are also increased. To effectively solve the problem of developing prefabricated, monolithic concrete and reinforced concrete structures with high strength and durability of concrete mixtures, and special chemical additives, the widespread use of superplasticizers is required. In particular, obtaining such products based on industrial secondary raw materials is more important.
Pyrolysis of hydrocarbon raw materials is the main method for obtaining low molecular mass olefins, mainly ethylene, propylene, and acetylene. The increasing production of ethylene and propylene has also led to increasing by-products generated in this process. A large amount of pyrolysis oil as a by-product is also obtained at pyrolysis. During the investigation, a naphthalene fraction was isolated from this product, and on its basis, a synthesis of superplasticizer for concrete mixtures was carried out. |
