Application

Maleic Anhydride, also known as maleic anhydride, maleic anhydride, 2,5 Furanedione, etc. . A colorless acicular or lamellar crystal of the RHOMBIC system. Strong pungent odor, soluble in ethanol, ether and Acetone, insoluble in petroleum ether and tetrachloromethane. Reacts with hot water to form MALEIC ACID.

Maleic Anhydride is mainly used in the production of unsaturated polyester resin, alkyd resin, pesticide Malathion, high-efficiency low-toxicity pesticide 4049, long-acting iodomine raw materials. It is also a copolymer monomer of paint, maleic Rosin, polymaleic anhydride and Maleic anhydride-styrene copolymer. It is also an organic chemical raw material for producing ink assistant, paper assistant, plasticizer, tartaric acid, fumaric acid, oxolane and so on.

Phthalic anhydride is the organic compound with the formula C6H4 (CO)2O. It is the anhydride of phthalic acid. This colourless solid is an important industrial chemical, especially for the large-scale production of plasticizers for plastics. Phthalic anhydride is an important chemical intermediate in the plastics industry from which are derived numerous phthalate esters that function as plasticizers in synthetic resins. Phthalic anhydride itself is used as a monomer for synthetic resins such as glyptal, the alkyd resins, and the polyester resins. Phthalic anhydride is also used as a precursor of anthraquinone, phthalein, rhodamine, phthalocyanine, fluorescein, and xanthene dyes. Phthalic anhydride is used in the synthesis of primary amines, the agricultural fungicide phaltan, and thalidomide. Other reactions with phthalic anhydride yield phenolphthalein, benzoic acid, phthalylsulfathiazole (an intestinal antimicrobial agent), and orthophthalic acid.

Phthalic anhydride is used in the manufacture of unsaturated polyesters and as a curing agent for epoxy resins. When used as a pigment, it can be responsible for sensitization in ceramic workers.n

oxalic acid
Oxalic acid is an organic substance with the chemical formula of C It is a metabolite of organisms. It is a binary weak acid, which is widely distributed in plants, animals and fungi and plays different functions in different organisms. It is found that more than 100 kinds of plants are rich in oxalic acid, especially spinach, amaranth, sugar beet, purslane, taro, sweet potato and rhubarb. Because oxalic acid can reduce the bioavailability of mineral elements, it is easy to form calcium oxalate with calcium ions in human body, resulting in kidney stones, oxalic acid is often considered as an antagonist for the absorption and utilization of mineral elements. Its anhydride is carbon trioxide.
