Example Embodiment

[0020] The present invention will be described in detail below in conjunction with the drawings and specific implementations:

[0021] figure 1 The purification method of thiothiazole shown includes the following steps:

[0022] a. Put the thiothiazole to be purified into the distillation kettle through the feed port, simultaneously turn on the vacuum pump and the vacuum valve to enter the pressure pump, and enter the spray device through the pipeline to obtain the thiothiazole to be purified in the gas phase, and the thiothiazole to be purified without vaporization is cyclically added Pressure spray; b. When the thiothiazole to be purified in the gas phase in step a rises to the distillation tower, the distillation tower is heated again, and then the thiothiazole to be purified in the gas phase continues to rise to the high-level condenser and becomes liquid sulfur Thiazole drops into the collector; c. the liquid thiothiazole in step b enters the visible reflux device composed ...

Abstract

The invention relates to a method for purifying sulfurol. The method comprises the following steps: putting to-be-purified sulfurol into a distillation kettle by virtue of a feed opening, and opening a vacuum pump and a vacuum valve at the same time, putting sulfurol into a pressure pump, then putting sulfurol into a spraying device by virtue of a pipeline to obtain gas phase to-be-purified sulfurol, and performing circular pressurization spraying on to-be-purified sulfurol which is not vaporized; when the gas phase to-be-purified sulfurol rises to a distillation tower, and heating the distillation tower again to ensure that the gas phase to-be-purified sulfurol continuously rises to a high-level condenser, changes into liquid sulfurol and falls into a collector; putting liquid sulfurol into a visible refluxing device consisting of glass pipelines by virtue of a pipeline, and closing the vacuum valve when the liquid sulfurol is rectified to have a needed sulfurol concentration; and opening a gas phase large valve, performing gas phase treatment on needed sulfurol, putting sulfurol into a low-level condenser by virtue of a pipeline, condensing sulfurol into liquid, putting liquid sulfurol into a finished product collecting tank by virtue of a pipeline, and collecting a finished product.

Description

technical field [0001] The invention relates to a chemical processing method, in particular to a method for purifying thiothiazole. Background technique [0002] Thiazole, organic compound, namely 4-methyl-5-(β-hydroxyethyl)-thiazole. It is light yellow liquid, non-volatile; non-flammable, non-explosive; non-corrosive; non-toxic. It is the basic structural ring of vitamin VB1 and an important intermediate for the synthesis of VB1. At the same time, it is also a precious spice with nutty, bean, milky, eggy, meaty, and used for nuts. Milky Meat and seasoning essence. [0003] The sulfur thiazole currently used in the market is obtained by decomposing thiamine. Generally, the purity of sulfur thiazole is about 70%, and the aroma is not pure, not bean-flavored; the color is too dark, dark brown; the production efficiency of the product is low. Contents of the invention [0004] The object of the invention is to provide a purification method that can obtain thiothiazole with...
