Bottom product of fractionator for trimethylcarbinol product dehydration is fed to additional fractionator. Preferably, the described method preparing brominated butyl rubber also comprises step: 3) be transported in tubular reactor by the product that hypergravity is obtained by reacting, and temperature of reaction is 0-30 DEG C, and the reaction times is 0.1-5min, obtains final product.When using this combined reactor to react, tubular reactor reacts the time of carrying out after can be used to accurate adults power reactor, and the control in reaction times is most important to quality product, particularly there is impact to the rearrangement of " EXO " structure and the utilization ratio of raw material bromine. SUBSTANCE: present invention pertains to new polymerisation methods, involving diluents and fluorohydrocarbons. Polyisobutylene, also known as "PIB" or polyisobutene, (C4H8)n, is the homopolymer of isobutylene, or 2-methyl-1-propene, on which butyl rubber is based. A process for obtaining above-defined butyl rubber in presence of catalytic system is also disclosed. Increase contact time of more than 72 hours is impractical because of the increased activity is terminated. There is use of fluorohydrocarbon diluent(s) or mixtures of diluents with hydrocarbons and/or mixtures of chlorinated hydrocarbons during polymerisation and copolymerisation of isoolefins with dienes, obtaining isoolefin copolymers with considerably reduced contamination of the reactor, and consequently, longer working periods of reactors. Preferably, described secondary solvent accounts for the 20-60% of total solvent volume. At lower contact times below 24 hours the activity of the catalyst falls below the optimum level. The catalyst - aluminium chloride, is protonated with water. The preferred embodiment of the present invention realizes in device flow process as shown in Figure 1; but the invention is not restricted to listed embodiment, also should be included in the hypergravity combined reactor that the present invention protects and prepare other any known changes within the scope of butyl rubber bromide gluing method. Further catalyst is deactivated, rubber is degassed, return products are fractioned in separation tower for isobutylene-chloromethyl and isobutylene-isoprene fractions, with further extraction of chloromethyl from isobutylene-chloromethyl fraction and division of isobutylene-isoprene fraction into isobutylene and isoprene-containing fraction. 4. a kind of method preparing brominated butyl rubber according to claim 3, is characterized in that, the reaction times in described tubular reactor is 1-2min.
