The invention relates to a single row condensing tube condensing and cooling device used for the synthesis of thionyl chloride, in particular to a single row condensing tube condensing and cooling device used for a fully-closed and full cycle thionyl chloride preparation process. The device comprises a single row condensing tube, a condensate container, a cooling passage, a pipeline and a recycle pump; in the device, due to the simple design of the single row condensing tube, the material is improved, the anticorrosion and pressure-proof capabilities are enhanced markedly, the service life is prolonged dozens of times; in addition, by the integration of a condenser and a cooling tower, the device reduces energy consumption by 20-30% and can be overhauled conveniently.
Description
technical field [0001] The invention relates to a single-row condensing tube condensing cooling equipment used for the synthesis of thionyl chloride. Specifically, the invention relates to a single-row condensing tube condensing cooling equipment used in a fully enclosed and full-cycle thionyl chloride preparation process. Background technique [0002] There are more than a dozen synthetic methods of thionyl chloride, but large-scale industrial production is basically the following three process routes: [0003] (1) Phosphorus pentachloride reacts with sulfur dioxide, the process is simple, but SOCl 2 with POCl 3 Difficult to separate, difficult to obtain high-purity SOCl 2 ; [0004] (2) Using antimony chloride etc. as a catalyst, sulfur chloride reacts with chlorosulfonic acid, which is widely used in China at present, with complicated process and large investment; [0005] (3) gas-phase catalytic synthesis of thionyl chloride, with active carbon as a catalyst, sulfur ...
