carbazole

Preparation and Application of Coumarone-Indene-Carbazole Resin as a Modifier of Road Petroleum Bitumen. 1. Influence of Carbazole:Raw Materials Ratio

The possibility of effectively using carbazole as an improver of coumarone-indene resin for use as a modifier of petroleum bitumens is studied. All starting materials for the production of coumarone-indene-carbazole resin (CICR) were obtained from various products of the coal coking process. The influence of raw material composition (amount of carbazole added to an industrial indene-coumarone fraction) on resin yield and its modifying properties was studied.

INFLUENCE OF TEMPERATURE ON THE PROCESS OF OBTAINING COUMARONE-INDENE-CARBAZOLE MODIFIER OF ROAD OIL BITUMENS

A narrow coumarone-indene fraction was obtained from liquid coal coking products. Based on this fraction and carbazole's presence, coumarone-indene-carbazole resin (CICR), a new type of kooligomers, was synthesized by ionic polymerization, which is proposed to be used as an adhesive modifier of road oil bitumens. The influence of temperature on the process of CICR synthesis, its quality, and characteristics of bitumen modified by it were studied.
