Title: Improvements in the manufacture of oxidation products of trichlorethylene
IPC: C07C51/58
Filed: 1939-01-04
Abstract: 523,555. Oxidation products of trichlorethylene. KIRKBRIDE, F. W., and IMPERIAL CHEMICAL INDUSTRIES, Ltd. Jan. 4, 1939, No. 321. [Class 2 (iii)] In the oxidation of trichlorethylene by gaseous oxygen, the trichlorethylene is exposed to active radiation at least up to the stage where the reaction liquor, when a sample is treated with water to decompose the oxidation products, has an acidity of at least 3N, and preferably between 15N and 20N, any subsequent oxidation being carried out at a temperature above 50‹ C., preferably between 65‹ and 75‹ C. The process may be carried out continuously, by oxidizing trichlorethylene exposed to actinic radiation until the desired acidity has been reached, and thereafter maintaining the reaction liquor at 65‹-75‹ C. and introducing trichlorethylene and oxygen and withdrawing oxidized liquor at such a rate that the acid value of the charge remains between 15N and 20N. The chief products are dichloracetyl chloride and trichlorethylene oxide ; the latter may be converted to the chloride by continued heating, preferably in the presence of a secondary or tertiary amine, e.g., dimethylamine, diethylamine, dimethylaniline or pyridine, which acts as a catalyst. Chloral may also be obtained by heating the oxidation products with an anhydrous metallic chloride, e.g., aluminium or antimony chloride. The dichloracetyl chloride may be converted into the amide or esters of dichloracetic acid by treatment with ammonia or the appropriate alcohol. Examples are given.

As shown in Fig. 1, the chamber 1 is provided with a double-leaf door 3, the leaves opening in opposite directions so that, whether reduced or increased pressure is used, one leaf is .automatically held in the closed position. The ventilation is maintained by a rotating piston air-pump 5 and a valve-controlled conduit 4 open to the atmosphere, which, as shown, operate to provide a reduced pressure; but an increased pressure may be obtained by reversing the flow of air, in which case the pipe 4 constitutes the exit. The pressure-regulating device comprises a valve 6, Fig. 2, arranged in the conduit 4 and actuated by a piston 7 pressed upwardly by atmospheric pressure and downwardly by an adjustable spring 8 and, through a connection 11, by the pressure within the chamber. In order to vary the amount of air passing through the chamber, the speed of the pump 5 may be suitably varied. A number of chambers may be united to form a single building, the partitions between the chambers being removable and ante-rooms being provided in which a pressure nearer to that of the atmosphere is maintained.
