Title: Improvements in or relating to the chlorination of hydrocarbons
IPC: C07C17/10
Filed: 1928-07-12
Abstract: 320,406. Ayres, E. E. July 12, 1928. Chlorinated hydrocarbons.-Hydrocarbons capable of existing in vapour phase at temperatures at which the rate of reaction with chlorine is low are chlorinated by introducing one vapour into the other while maintaining one of the vapours in motion at a velocity sufficiently high to prevent ignition or persistence of ignition at the point of mixture, e.g. at a velocity in excess of one half of the velocity required for turbulent flow of the mixture i.e. 50 ft. per second in a conduit not more than 8 inches in diameter, providing the temperature is such that the velocity of reaction is low. The velocity sufficient to prevent ignition depends upon the ratio of chlorine to hydrocarbon and upon the temperature of the mixture and must be increased with rise of temperature and the approach to explosive proportions in the mixture, e.g. the velocity of reaction between the vapours of pentanes and chlorine is low at temperatures below 150 C. Saturated aliphatic hydrocarbons containing 3-6 carbon atoms may be chlorinated by mixing reactants in the above manner, and then bringing the mixture with minimum delay to a reaction chamber, and initiating and completing the chlorination under the influence of a suitable agent e.g. heat, thereby preventing the formation of some chloride during the passage to the reaction vessel,.and consequent formation of higher chlorides during the reaction.
