Product Details

1. Foreword
Inner Mongolia Shuangxin Environment-Friendly Material Co., Ltd. is a national high-tech enterprise, mainly engaged chemical and chemical fiber production in calcium carbide - acetylene industry line with mature technology, advanced production equipment, strong technical force. We set up our own technology center and R & D center with support and certification from Inner Mongolia authority. The company’s production system has got ISO certification etc which support product’s good quality. Inner Mongolia Shuangxin Environment-Friendly Material Co., Ltd. mainly produce polyvinyl alcohol (PVA), vinyl acetate (VAM), acetaldehyde, methyl acetate, PVA fiber cement, cement etc. The company can develop different strength, modulus and more grades PVA fiber products with first-class quality according to customer requirements.

3. Manufacturing Method
Calcium carbide reacts with water to get acetylene, acetylene is cleaned and get rid of impurities to be fine acetylene, fine acetylene and acetic acid are put into the synthesis reactor, to obtain a reaction liquid from the synthesis reaction at a certain temperature with activated carbon as a carrier and zinc acetate as a catalyst .The reaction solution is refined and separated to become the product vinyl acetate.

4. The physical and chemical properties

Vinyl acetate is a colorless transparent liquid with a sweet smell of ether; slightly soluble in water, soluble in alcohol, acetone, benzene, chloroform and a variety of organic solvents. Vinyl acetate relative density (water = 1) 0.93, boiling point of 71.8 ° C, flash point -8 ° C, the freezing point of -93 ° C spontaneous combustion point of 427 ° C, its vapor and air can form explosive mixtures, air explosion limit 2.6-13.4% (volume). In case of fire, high-heat combustion it can cause the explosion.

vinyl acetate has active chemical properties, it react with a halogen, hydrogen halides, halogenated hydrocarbons, phenols, ammonia, mercaptans, hydrogen cyanide, amines, etc.; rapid hydrolysis make acetate and acetaldehyde when react with inorganic acid, salt, alkali ; polymerization reaction in the heat, light, or trace peroxide, an azo, even if vinyl acetate contain inhibitor will have violent polymerization reaction reacting with peroxide; occur binary, ternary and multi-copolymer with vinyl chloride,acid, crotonic acid, maleic acid and other unsaturated acids; reaction to produce acetic anhydride and acetic acid in sulfuric acid under acylation reaction and secondary alcohols in alkaline medium and it can react with oxidants.

5. Main application

Vinyl acetate is a kind of widely used basic organic chemical raw materials, mainly for the production of polyvinyl alcohol resin, EVA resin, EVOH resin, polyvinyl butyral resin, synthetic fiber, VAE emulsion and VAC emulsion, etc., its single poly and the copolymer adhesive can produce a variety of purposes. Vinyl acetate is widely used in the textile, coating, adhesive, film, medicine, organic synthesis, fine chemical industry, daily chemical industry.

6. Security,storage and transportation

Vinyl acetate national standard number is 32131, CAS: 108-05-4, EINECS number is 203-545-4,Danger tags is 7 (flammable liquid). Vinyl acetate belong to flammable solid, should stay away from fire, prevent warm sun, storage tank should have obvious "flammable liquid" logo, on the storage tank with nitrogen pressure storage, storage tank on top device should be equipped with a spray cooling water in high temperature season, tank region should be built accident pool or accident cofferdam tank. The products are shipmented by tank car or clean and dry aluminum drum or galvanized iron bucket. the container should be obvious danger tags, stored in a well ventilated warehouse within the storage temperature should be less than 30 ℃. Warehouse need to conform to the stipulations of the "flammable" dangerous goods warehouse, Shall not be put with other "flammable" objects, are strictly prohibited to put intense chemical reaction occurs with objects. When loading and unloading should be light discharge and anti-static device, dock should be far away from populated areas when on the way. Anyone who contact with vinyl acetate must be familiar with industrial safety regulations of vinyl acetate. To ensure safety,each batch production of vinyl acetate should be attached with inspection report. Test report include the following contents: the production manufacturer, product name, test date, tester, report for approval and approver.
