Abstract
Description
Technical Field
[0001] The utility model relates to a reaction kettle, in particular to a heating reaction kettle for preparing magnesium stearate, belonging to the technical field of stearate production. Background Art
[0002] Magnesium stearate belongs to one of the stearates, also known as magnesium octadecanoate, which has the dual characteristics of metal salts and stearic acid. Magnesium stearate is prepared by double decomposition, and magnesium hydroxide needs to be added to the reactor first. Stir evenly under low temperature environment, then add stearic acid and glacial acetic acid, continue to stir evenly under high temperature environment, and after the reaction is complete, the magnesium stearate is precipitated and separated. When magnesium stearate is prepared by this process, the reactor needs to be first heated at low temperature and kept warm, and then heated at high temperature and kept warm. Conventional heating technologies such as electric heating wires are prone to local over-temperature and cause stearic acid to decompose. Therefore, the reactor of magnesium stearate is usually heated by an interlayer medium. Since two-stage heating is required, the temperature of the medium in the interlayer needs to change. The conventional heating water tank circulates, and after the interlayer water is heated to a high temperature, it needs to be cooled (natural cooling is too slow, and air cooling or heat exchanger is often used to accelerate cooling) before the next production can be carried out. The efficiency is low, and a large amount of heat is wasted during cooling, resulting in energy waste. Utility Model Content
