Description white or light yellow crystalline powder. Easily soluble in methanol and ether, hardly soluble in hot water, and can be volatilized with water vapor; phthalic acid is obtained by oxidation, which can be used as intermediates of medicine, photosensitive materials, pesticides, and organic pigments. Mainly used in the manufacture of hemostatic aromatic acid, p-formonitrile, p-toluoyl chloride, photosensitive materials, etc. It is used in organic synthesis intermediates and pesticide industry to prepare bactericide phosphoramide, and it can also be used in perfume and film film.
Intermediates for medicine, photosensitive materials, pesticides and organic pigments. Mainly used in the manufacture of hemostatic aryl acid, p-methylonitrile, p-toluenyl chloride, photosensitive materials, etc. Used in organic synthesis intermediate, pesticide industry to produce fungicide phosphamide, also can be used in spices and film.
