As the intermediate of organic synthesis raw materials, tetrahydrophthalic anhydride is generally used to produce alkyd resin, unsaturated polyester resin, coating, curing agent of epoxy resin, insecticide, curing regulator, plasticizer and surfactant. Tetrahydrophthalic anhydride, as the raw material for the production of unsaturated polyester resin, mainly improves the air dryness of the resin, especially in the production of high-grade resin atomic ash and air dry coating.
Epoxy Resins
All the polymer compounds containing epoxy group in molecular structure are called epoxy resin. The cured epoxy resin has good physical and chemical properties. It has excellent bonding strength to the surface of metal and non-metal materials, good dielectric properties, small variable shrinkage, good dimensional stability of products, high hardness, good flexibility, and stability to alkali and most solvents. Therefore, it is widely used in various departments of national defense and national economy for pouring, impregnation, laminating materials Adhesive, coating and other applications. Epoxy resin has been studied since 1958 in China, and it has been put into industrial production at a very fast speed. Up to now, it has developed vigorously all over the country. In addition to the production of ordinary bisphenol a-epichlorohydrin epoxy resin, various types of new epoxy resin are also produced to meet the urgent needs of national defense construction and national development and economic departments. The preparation methods of epoxy resin are as follows: reaction of active hydrides with epichlorohydrin, liquid-phase oxidation of double bond by hydrogen peroxide or peracetic acid (for example, peracetic acid), air oxidation of double bond compounds.
Hexahydrophthalic Anhydride
Hexahydrophthalic anhydride, also known as hexahydrophthalic anhydride, is a colorless, transparent and viscous liquid at room temperature. Molecular weight 154.17. At 35-36 ℃, it solidified into a white glassy solid. The relative density is 1.18-1.19. Boiling point 158 ℃ (2.27kpa). Soluble in acetone, ethanol, ethyl acetate, chloroform, carbon tetrachloride, benzene, toluene, slightly soluble in petroleum ether. Inhalation is toxic and has strong irritation to eyes and skin. Hexahydrophthalic anhydride can be used as curing agent of epoxy resin. It has low melting point, can be mixed with resin at low temperature, low viscosity of mixture, long service life (6 days), and small heat during curing. Mainly used for casting products. The general dosage is 75-85 phr. Curing conditions: 100-200 ℃ / 3-1h. The electrical properties and drug resistance of the cured products are excellent, and the heat deformation temperature is 110-130 ℃. Hexahydrophthalic anhydride can also be used as a eutectic curing agent for chlorobridged anhydrides and tetrahydrophthalic anhydrides.
