Title: Improvements in or relating to the manufacture of halogenhydrins
IPC: C07C29/66
Filed: 1925-10-02
Abstract: 265,259. Long, C. L., Willson, F. G., and Wheeler, T. S. Oct. 2, 1925. Halogenhydrins; ethylene chlorhydrin. Halogenhydrins, more especially chlorhydrins, are prepared by absorbing the halogen in pure water and reacting the product, without the addition of inorganic salts or bases, with one or more compounds each containing one or more ethylene linkages. The water may be circulated through a number of mixing devices in one or more of which it is treated with halogen, and in the other or others it is brought into contact with the olefine. The olefine absorption may be conducted under pressure. The temperature is preferably maintained between 0-25‹ C. during the process, cooling being employed if required. The preparation of ethylene chlorhydrin is described, water being passed from a constant-level reservoir 3 through a pipe 4 to a scrubbing tower 1, where it meets chlorine introduced continuously through a valve 14 and pipe 15 at such a rate that a suitable amount is dissolved, e.g. 0.1 gm. per 100 c.c. The solution flows out through a pipe 5 into a reservoir 23 and thence, through pipe 6, to a second scrubbing tower 2, into which ethylene is introduced through valve 16 and pipe 17 at such a rate that it is just completely absorbed. The chlorhydrin solution passes off though pipe 7 to a tank 8, from which it may be sent by a pump 12 through pipes 11, 13 to tank 3 and again passed through the apparatus. The chlorhydrin solution is circulated continuously through the apparatus, and its concentration is maintained at about between 8-10 per cent by the continuous withdrawal of a portion of the solution from tank 8 through pipe 20 and the addition of an equivalent amount of water to the tank 3. Heavy insoluble oily by-products may be withdrawn at any convenient point, preferably from the tank 8 through a lower pipe 21 and cock 22. The apparatus is arranged so that no gaseous chlorine and ethylene can come into contact, pipes 24, 25 being provided to return any gas trapped by the liquid from tanks 23, 8 to the towers 1, 2. The ethylene absorption may be effected at 6 atmospheres pressure, and the chlorine absorption at or below atmospheric pressure, the absorption being observed and regulated bv the aid of water seals 18, 26. The chlorhydrin solution obtained may be worked up to give anhydrous chlorhydrin, for example by utilizing it to prepare gaseous ethylene oxide according to the process described in Specification 236,379, the ethylene oxide being treated with dry gaseous hydrogen chloride to obtain the chlorhydrin in apparatus provided with means for removing the heat produced. Where the halogenhydrin is insoluble in water it may be removed as a precipitate.
