Chlorination butyl rubber

Chlorobutyl rubber is prepared by chlorination of butyl rubber (chlorine content is about 1 wt%). This is a substitution reaction produced at the allylic position, so little carbon-carbon double unsaturation is lost. Therefore, chlorobutyl rubber has enhanced reactivity of the carbon-carbon double bonds and supplies additional reactive sites for cross-linking. Furthermore, enhanced adhesion is obtained to polar substrates and it can be blended with other, more unsaturated elastomers. [Pg.585]

Chlorinated butyl rubber. Chlorination or bromination of butyl rubber overcomes the difficulty of vulcanising butyl rubber in mixtures with more highly unsaturated substances due to the preferential absorption of the sulphur by the more highly unsaturated component. Chlorohydrin Rubbers... [Pg.17]

As in industry including butyl rubber chlorination and piperylene cationic oligomerization we often have to use liquid flows with different physical characteristics (density, viscosity) it is necessary to study the influence of these parameters on conditions of reaction plan front formation - quasi-plug-flow mode, and consequently on the effectiveness of external heat removal. [Pg.90]

Since chemical reaction time is small (Tch = 6 sec) liquid-phase butyl rubber chlorination process in solution with molecular chlorine should be ascribed to novel class of chemical processes - fast chemical reactions that should be carried out also according with principally novel technology with the use of highly productive compact tubular turbulent apparatus of jet type. [Pg.115]

On the base of studying of specificity of process of butyl rubber chlorination in solution by molecular chlorine, conditions of formation of self-similar field of liquid flows and regularities of multi-phase flows in tubular canals (see Chapter 3) compact tubular turbulent pre-reactor-chlorator (Fig. 6.5) with originai nozzles (Fig. 6.6) was developed and approved on OAO "Nizhne-kamsneftekhim" (Patent Russia No. 2170237, priority from 30.07.1999, published on 10.07.2001, bulletin No. 19 Patent Russia No. 2170238, priority from 30.07.1999, published on 10.07.2001, bulletin No. 19). [Pg.147]
