Hydrocarbon resins (oligomers) are produced on the basis of fraction C9 of oil refining by-products. The low-temperature emulsion oligomerization can reduce the temperature and duration of the process compared to the existing technologies.
At pyrolysis of hydrocarbon raw materials on ethylene plants significant amounts of liquid by-products are formed. It is possible to synthesize hydrocarbon resins that are used as film forming agents in anti-corrosion and lacquer coatings based on the C9 fraction of liquid by-products of pyrolysis. The use of low temperature emulsion oligomerization can simplify the purification of the target product and whie the synthesis can be performed at low durations and temperatures.
Cooligomerization of unsaturated hydrocarbons of C9 fraction of diesel fuel pyrolysis liquid products and terpenic hydrocarbons of turpentine has been studied using catalysts of different nature. Physical-chemical properties of the aromatic-terpenic resins obtained with these catalysts have been compared.
