Description

Technical Field

[0001] The utility model relates to the technical field of aminosulfonic acid preparation, in particular to a circulation tank for aminosulfonic acid production. Background Art

[0002] Aminosulfonic acid is an inorganic solid acid formed by replacing the hydroxyl group of sulfuric acid with an amino group. Its chemical formula is NH2SO3H, and its molecular weight is 97.09. It is generally white, odorless, rhombic flaky crystals with a relative density of 2.126 and a melting point of 205°C. It is soluble in water and liquid ammonia. At room temperature, as long as it is kept dry and not in contact with water, solid aminosulfonic acid does not absorb moisture and is relatively stable. The aqueous solution of aminosulfonic acid has the same strong acidity as hydrochloric acid and sulfuric acid, so it is also called solid sulfuric acid. It is non-volatile, odorless and has low toxicity to the human body. Aminosulfonic acid can be used to synthesize herbicides, fire retardants, sweeteners, preservatives, metal cleaning agents, etc. It is a common chemical raw material.

[0003] Aminosulfonic acid is an important organic compound with a wide range of applications. It can be used in the pharmaceutical, cosmetic, food and other industries, and is also widely used in the agricultural field. When preparing aminosulfonic acid, an acid circulation tank is often required. The existing acid circulation tank has a relatively simple structure and cannot effectively guarantee the reaction time and reaction temperature to be accurately controlled during the preparation of aminosulfonic acid. In addition, the adhered impurities inside the circulation tank are likely to cause reaction interference, which is not convenient for the preparation and use of aminosulfonic acid. Therefore, a person skilled in the art provides a circulation tank for aminosulfonic acid production to solve the problems raised in the above background technology. Utility Model Content
