ОRTO-PHOSPHORIC ACID AS AN ALTERNATIVE TO HYDROCHLORIC ACID – FOR CATIONIC BITUMEN ROAD EMULSIONS. REVIEW

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.

Emulsion oligomerization of С9 fraction of oil refining by-products initiated by potassium persulfate

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.

Коолігомеризація в емульсії вуглеводнів фракції с9 з використанням персульфату калію

 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. Одержано коолігомери за допомогою коолігомеризації в емульсії вуглеводневої фракції С9 рідких продуктів піролізу. Встановлено основні закономірності та вибрано оптимальні умови процесу коолігомеризації суміші ненасичених вуглеводнів фракції С9.
