Description

Technical Field

[0001] The utility model relates to the field of aminosulfonic acid processing, in particular to a heating kettle for aminosulfonic acid. Background Art

[0002] Aminosulfonic acid is a colorless crystal, and its aqueous solution is acidic. Aminosulfonic acid is an important fine chemical product with a wide range of uses. There are many methods for synthesizing aminosulfonic acid, among which the oleum method uses oleum and urea as raw materials. Excess oleum is added to the reactor, stirred and cooled to a suitable temperature, and sulfuric acid and urea mixed in proportion are added. After the addition is completed, it is stirred for about 8 hours, and then gradually heated to 70℃-90℃, cooled and crystallized, and crude aminosulfonic acid is obtained after solid-liquid separation. It is recrystallized with water and dehydrated to obtain high-purity fine aminosulfonic acid.

[0003] At present, when aminosulfonic acid is reacted in a reactor, a heater is usually set at the bottom for heating, or a winding steam pipe is set for heating. However, this heating method is difficult to use for long-term heating and is likely to cause heat loss, thereby increasing the heating cost during the reaction of aminosulfonic acid. Therefore, those skilled in the art provide a heating kettle for aminosulfonic acid to solve the problems raised in the above background technology. Utility Model Content
