Douwin Chemical is a styrene maleic anhydride supplier whose average employee age is less than 30 years old, and one that has gained a certain reputation in the industry. In 2017, Suzhou Douwin Chemical Co., Ltd. was listed as a key private enterprise in Taicang City. Our company has the advantages of geographical location and the forefront of business philosophy. The most fundamental one is the cohesion of outstanding talents.It provide types of chemical compounds, such as adipic acid, maleic anhydride, phthalic anhydride, acrylic acid and so on.
Maleic anhydride often abbreviated as MA, is an organic chemistry compounds. It is a colorless crystal, strong stimulating smell, and easy to sublimate. HS code is 29171400. It is mainly obtained from the oxidation of n-butane or butene in benzene or carbon four fractions and is a raw material for the production of unsaturated polyester and organic synthesis.
Features of Maleic Anhydride (MA) China
It should avoid contact with moist air, a strong oxidizer, strong reducing agent, strong acid, strong base, alkali metal, and water. The rhombic system is a colorless acicular or lamellar crystal. It dissolves in ethanol and produces esters. Soluble in ethanol, ether, and other organic solvents, difficult to dissolve in petroleum ether and carbon tetrachloride. It reacts with hot water to form maleic acid. It is easy to copolymerize olefins. Homopolymerization is also possible. It reacts with a diol to form linear unsaturated polyester and with sulfur trioxide to form sulfonated maleic anhydride.
