Rubber Auxiliaries Zinc Benzenesulfinate
Chemical Name: Zinc Benzenesulfinate
Molecular Formula: C12H10O4S2Zn Structural Formula:
Molecular Weight:347.73 CAS NO:24308-84-7
Zinc Benzenesulfinate is an inorganic compound with the chemical formula C6H5SO3Zn, it is a white crystalline powder, soluble in water and organic solvents.
Zinc benzenesulfinate is commonly used as a catalyst in organic synthesis, especially for the oxidation of aromatic hydrocarbons with high catalytic activity. It is also used as an additive in the dye industry, dye labelling and electronics.
Zinc benzenesulfinate can be prepared by reacting benzenesulfonic acid with zinc oxide under appropriate conditions, after which it can be crystallised and filtered to obtain a product of high purity.

Product Properties: white powder, insoluble in water, non-toxic, specific gravity 1.52, soluble in nitric acid. Slightly soluble in chloroform, acetone, benzene and carbon tetrachloride, insoluble in petrol and ethyl acetate, decompose when meet strong alkali or strong acid solution, especially nitric acid.
Product Usage: This product is suitable for the activation of ADC raw powder of foaming agent, which can reduce the decomposition temperature of AC foaming agent, improve the activity of AC, reduce the use of AC foaming agent, activate and promote the foaming of AC, and improve the amount of gas. It can be used in rubber-plastic foam processing and heat preservation materials.
Package: 25kg plastic woven bag, paper-plastic composite bag, kraft paper bag.
Storage: It should be stored in a cool, dry and well-ventilated place. Packed products should be avoided from direct sunlight, valid for 2 years.
Zinc Benzenesulfinate requires the following safety information during general use and storage:
1. Avoid contact with skin and eyes and wear appropriate protective equipment when using.
2. Avoid inhalation of product dust, if excessive dust is inhaled, move immediately to a well ventilated area.

Company information
The company's main import and export products include
（1）Flavours and Fragrances are volatile substances. They have a certain aroma and fragrance, can be people smell taste out (some aroma and fragrance in the case of people can not be perceived by the senses, but will be different creatures feel and distinguish out); requirements to achieve the purpose of the people's favourite, the spirit of pleasure and enrichment and beautification of the material and cultural life of the people.
（3）Intermediates:It is a very important type of fine chemical products, the essence of a class of "semi-finished products", is the production of some products in the middle of the product, such as to produce a product, can be produced from the intermediates, cost savings, from the synthesis of pharmaceuticals, pesticides, paints, dyes and fragrances are widely used. In the pharmaceutical field, intermediates are an important link in the pharmaceutical industry chain, used in the process of drug synthesis of some chemical raw materials or chemical products, in a word, used to produce APIs.Our Intermediates products include Synthetic material intermediates,dye intermediates, Flavors and Fragrances intermediates.
