Description

TECHNICAL FIELD

[0001] The utility model relates to the technical field of OB acid production technology, specifically to a hydrolysis kettle for OB acid production and processing convenient for discharging. BACKGROUND

[0002] OB acid is mainly used for preparing fluorescent whitening agent, especially fluorescent whitening agent EBF. This whitening agent can be used for the whitening of synthetic fibers such as nylon, polyester, polypropylene, chlorofiber and triacetate fiber. In addition, OB acid is also used for the whitening of plastic film, compression molding material and injection molding material. The preparation method of OB acid comprises the following steps: adding adipic acid and thionyl chloride according to a weight ratio of 1:5-12 into a reaction kettle, adding a catalyst and heating to 75-95 DEG C for reaction to generate acyl chloride. Hydrolyze the acyl chloride to be completely solid, adjust the pH value to 9-12, heat to 81-85 DEG C for 2-2.5 hours, and then carry out decolorization treatment. Add hydrochloric acid to the filtrate, stir and centrifuge to obtain a crude product. Heat the crude product to reflux, filter to obtain a refined product. Dry, crush and package the refined product to obtain the product. In the processing process, for the reaction kettle, after the hydrolysis reaction, the reacted material is generally discharged from the bottom, and the reactants and raw materials participating in the reaction are generally also layered. Therefore, during the discharging process, the material in each layer needs to be discharged one by one.

Therefore, the utility model provides a hydrolysis kettle for OB acid production and processing convenient for discharging, which can conveniently discharge any layer, has high discharging accuracy and fast speed, and further improves the efficiency of OB acid production.
