emulsifier

It has been studied the production of petroleum resins by low-temperature inverse emulsion oligomerization of C9 fraction of diesel fuel pyrolysis liquid by-products. It is established that the determining factors of the C9 fraction of the inverse emulsion oligomerization are the following: reaction time, emulsifier concentration and phase ratio.  Yield and physicochemical characteristics of oligomers сorrelations were established.

Slow-breaking monophase cationic bitumen emulsions have been produced on the basis of bitumen modified with phenol-cresol-formaldehyde resin (PhCR-F). Bitumen emulsions were used as a binder for thin-layer coatings with slurry surfacing mixes (SSM). Physical and technical parameters of modified and unmodified emulsions were determined and analyzed. The optimal compositions of SSM were selected according to the breaking criterion. The values of SSM wet track abrasion were determined.

The road slow-setting monophase cationic bitumen emulsions have been prepared from bitumen modified by coumarone-indene resin with epoxy groups. Еmulsions were obtained using a colloid mill at the standard temperatures (413–423 K). The physico-technical parameters of modified monophase emulsions have been established and the comparative analysis with the basе sample has been made.

In this article the cationic bitumen emulsions are characterized – as popular binder for various road emulsions. There are considered the specific features of cationic bitumen road emulsions’ formulations. There are presented the functions and specificities of the acids application in cationic bitumen road emulsions. The literary review is presented on potentialities of ortho-phosphoric acids application instead of the traditional hydrochloric acid.

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.

 The synthesis of cooligomers by cooligomerization in the emulsion of hydrocarbon C9 fraction of liquid pyrolysis products is described. The major features of the cooligomerization of a mixture of unsaturated hydrocarbons of C9 fraction have been investigated and optimum process conditions have been selected.
