CHARACTER

resorcinol, chemical formula C6H6O2, is a white or light yellow crystal, with a special phenolic odor, slightly soluble in water, soluble in ethanol, ether and other organic solvents. Resorcinol is an important organic chemical raw materials and intermediates, widely used in dyes, rubber, pharmaceuticals and pesticides and other industries. In the manufacture of dyes, it is used as a raw material for the synthesis of a variety of dyes to improve the color and stability of dyes; in the rubber industry, resorcinol is used to manufacture rubber antioxidants to improve the aging resistance of rubber; in addition, it is also Used in the manufacture of medicines and pesticides, as the key raw material for the synthesis of a variety of drugs and pesticides. As a multifunctional organic compound, resorcinol has been widely used in many industrial fields.

APPLICATIONS

(1) Resorcinol is often used as an adhesive in the rubber industry, especially the condensation polymer formed with formaldehyde, which can be used in the manufacture of tire cord adhesives, wood adhesives, etc., to improve the adhesion and durability of rubber products.

(2) In the dye industry, resorcinol is an important intermediate for the synthesis of a variety of dyes, such as azo dyes, fur dyes, etc., these dyes are widely used in textile, leather and other industries, adding a wealth of color to the product.

(3) Resorcinol has a bactericidal effect and can be used as a preservative and antibacterial agent in the field of medicine. It is used to make dermatological drugs, disinfectants, etc., and helps prevent and treat skin diseases caused by microorganisms.

(4) In addition, resorcinol is also used to synthesize high-performance pigments with excellent light stability and weather resistance. It is suitable for paints, coatings, inks and other fields, and improves the color performance and durability of products.
