Initiated by Organic Peroxides Cooligomerization of Unsaturated Hydrocarbons of C5 fraction – By-product of Ethylene Production

Bohdan Dzinyak¹,

Stepan Melnyk²

Abstract: Initiated by organic peroxides cooligomerization of unsaturated compounds of C 5 fraction has been studied. Such fraction is a by-product obtained at ethylene production via hydrocarbon raw material pyrolysis. The main regularities of the process have been established, the effect of main factors (temperature, reaction time, nature and concentration of the initiators) on the yield and physico-chemical characteristics of the obtained cooligomers has been examined. The effective initiator and optimal technologica… Show more

The results of the study of the use of oligomers obtained by di-tert-butyl peroxide-initiated oligomerization of C5 and C9 hydrocarbon fractions of liquid by-products of ethene production by pyrolysis of petroleum raw materials as synthetic substitutes for vegetable oil in the production of paint materials, in particular Oxol oils, are given. It was established that the use of 54.5 wt. % of the oil A 60 % solution of the oligomer in white spirit makes it possible to obtain a product that meets the requirements of TU U 20.3-37168270-044:2017, which will allow the release of significant amounts of edible vegetable oils, which are used for technical purposes in the paint industry of Ukraine.

The article proposes the use of peroxide initiators for the synthesis of reactive hydrocarbon oligomers with anhydride and carboxyl groups based on hydrocarbon fractions C5–9. Effective initiators of the process were selected, which made it possible to obtain high yields of co-oligomers. Ways of practical application of the synthesized co-oligomers were investigated. The possibility of using reactive co-oligomers for the production of polymeric protective materials and composite materials with specified properties is proposed. Functional groups and double bonds improve the physico-mechanical (adhesion, strength, stability) and chemical (acid number, saponification number) properties of the obtained hydrocarbon oligomers.

The suspension oligomerization of the unsaturated hydrocarbons of the C9 fraction of liquid by-products of diesel fuel pyrolysis initiated by N-(tert-Butylperoxymethyl)-4- chloroaniline was investigated. The influence of reaction conditions (reaction temperature and time, mixing intensity, dispersed phase content, initiator concentration) on the yield and physico-chemical characteristics of hydrocarbon resins was determined. The optimal reaction conditions were selected. The temperature dependence of the relative and dynamic viscosity of the obtained hydrocarbon resin solutions was determined.
