Vinylene Carbonate (VC) Technology Introduction
Synthesis process of CEC: EC reacts with chlorine in the photolysis reaction tower under the catalysis of ultraviolet light, and then neutralized with liquid alkali. CEC after reaction contains certain chlorine and hydrogen chloride. Nitrogen is used for stripping, and the stripping waste gas is sent to the hydrochloric acid absorption tower.
Synthesis process of VC: DMC (dimethyl carbonate) was solvent and triethylamine as catalyst to remove hydrogen chloride in the reactor. After centrifugal filtration, the solution containing solid triethylamine hydrochloride enters the desolvention tower, crude distillation tower, distillation tower and crystallizer to obtain qualified products.
Advantages of Synthesizing Intermediate CEC Technology
1
Equipped with the external UV lamp, which is safe and reliable;
2
Large feeding amount of the equipment;
3
Fast reaction rate, good product quality and low chlorine consumption.
Advantages of Synthesizing Product VC Technology
1
It’s a unique product separation and purification technology with high separation yield and good product quality, which the risk of conventional technology separation is greatly reduced;
2
It is exclusive in the industry since it adopted falling-film crystallization technology, which the investment is lower, the occupied space is smaller and the crystallization yield is higher. less

#calcium #carbonate #manufacturers
Light Calcium Carbonate, also named precipitated calcium carbonate, is a kind of active calcium carbonate. The manufactured process of light calcium carbonate is achieved by chemical synthesis. Because its settlement volume (2.4-2.8mL/g) is larger than that of the heavy calcium carbonate produced by mechanical method (1.1-1.9mL/g), it is called light calcium carbonate.
Light Calcium Carbonate Characteristics
* The particle size is smaller than that of heavy calcium carbonate; Better fineness.
* Better whiteness.
* Less impurities; high purity.
* The appearance is mainly spindle or spherical shape.
* Good dispersion
Light Calcium Carbonate Main Applications
Light calcium carbonate has a wide range of functions and can be used in the following industries:
The rubber industry: calcium carbonate is one of the earliest largest filling agents used in the rubber industry.
2）Plastics industry: calcium carbonate play a great role in the stability of plastic products, improve the hardness of the products, and improve the surface gloss and surface smoothness of the products.
3）Paint industry
4）Water-based coatings industry
