Resorcinol

Resorcinol is commonly known as "Leisuoxin". This product has bactericidal, fungicidal and antipruritic effects, its bactericidal effect is 1/3 of that of phenol, and its irritation and corrosiveness are also less. Low concentration has the effect of promoting keratin regeneration, and high concentration has the effect of keratin exfoliation. Mainly used for rubber adhesives, plastics, synthetic resins, synthetic fibers, dyes, preservatives, antipruritic, antifungal agents, analytical reagents, and also for the treatment of ringworm, eczema, seborrheic dermatitis, acne and psoriasis Wait.

Resorcinol is an important organic synthesis raw material, mainly used in rubber adhesives, analytical reagents, preservatives, drugs, dyes, synthetic resins and other raw materials, such as eosin is an important triphenylmethane dye, dyed bright red, Mainly used for dyeing silk, it is prepared by co-heating resorcinol and phthalic anhydride in the presence of zinc chloride or concentrated sulfuric acid to prepare intermediate fluorescent yellow, and then tetrabrominated. Eosin is often used to make red ink and can also be used as a stain for biological materials for microscopic examination. If the intermediate fluorescent yellow is brominated in acetic acid solution, it can only be dibrominated, and then co-heated with mercuric acetate to obtain red mercury (also called mercury bromide red), which is an important disinfectant and preservative. It is easily soluble in water, and a 2% aqueous solution is the "red syrup" for daily sterilization and disinfection. An alcohol-acetone solution of mercuric can also be used for skin disinfection. Resorcinol and hexanoic acid are re-reduced through acylation reaction to obtain 4-n-hexyl quinone, which is also a disinfectant. In medicine, it is also used as a local anti-itching agent and intestinal digestive agent.
