Phthalic anhydride typical Usage
- Phthalic anhydride is one of the most important organic chemical raw materials. Its main derivatives are dibutyl phthalate; dioctyl ester and diisobutyl ester, etc., used as plasticizers for PVC, etc .; Saturated polyester resins; alkyd resins; dyes and pigments; various paints; food additives; phenolphthalein, a laxative in medicine; imidophos in pesticides; bentazone and saccharin sodium.
- This product is used as an epoxy resin curing agent. This product is an important organic chemical raw material, mainly used in the production of phthalate plasticizers, coatings, saccharin, dyes and important intermediates of organic compounds, insecticides, fungicides, rubber processing aids, photosensitive materials Wait.
- Used as analytical reagent. Organic synthesis intermediate. The dye industry is used to prepare important intermediates such as anthraquinone, 2-chloroanthraquinone, 1,4-dihydroxyanthraquinone and phthalocyanine blue BS, phthalocyanine blue BX, phthalocyanine blue B and other dyes.
- Used as a curing agent for epoxy resin, the reference dosage is 30-50 parts by mass, the pot life of 100g resin complex is rt / 6h, 120 ℃ / 1.5h. Curing conditions: 100 / 2h + 150 ℃ / 5h or 100 ℃ / 12h, 140 ℃ / 8h, 200 ℃ / 6h. The heat generation during curing is small, the cured product has good electrical properties and mechanical strength, and the heat deformation temperature is 110 to 152 ℃.
- It is an important organic chemical raw material. In the synthetic resin industry, it is used to produce polyester resin, amino resin, unsaturated polyester resin, alkyd resin, etc. Dyestuff industry is used to prepare dye intermediates such as anthraquinone, chloroanthracene dihydroxyanthraquinone and phthalocyanine blue BS, phthalocyanine blue BX, phthalocyanine blue B and other dyes. Plastic industry is used to prepare plasticizers such as dibutyl phthalate, dioctyl phthalate and their mixed esters. It is also an important intermediate for manufacturing various medicines, paints and organic compounds.
- Used in the manufacture of plasticizers, dibutyl phthalate, resins and dyes.
