Abstract
Light-coloured rubber hydrochloride is produced by causing chlorine dioxide to act in a low concentration on a solution of rubber hydrochloride. The chlorine dioxide may be used in the gaseous form, dissolved in a solvent such as benzene, or by adding sodium or potassium chlorite to a solution containing free hydrogen chloride. The reaction is allowed to continue for from about 30 minutes to 10 hours and excess chlorine dioxide is removed by blowing air or an inert gas such as nitrogen or heating at 60-70 DEG C., the hydrochloride is then worked up in the usual way. The hydrochloride may be dissolved in benzene, toluene, xylene, chloroform or dichlorethylene. Specification 437,304 is referred to.
