Salicylic acid is an important organic synthetic raw material, widely used in medicine, pesticides, rubber, dyes, food and flavor industries.

a. In pharmaceutical industry, salicylic acid can be used to produce the drugs of sodium salicylic acid, methyl salicylate, acetylsalicylic acid, salicylic acid amine, salicylic acid phenyl ester, etc.

b. In dye industry, salicylic acid can be used to produce mordant pure yellow, direct yellow 3GN, direct yellow GR, direct brown 3GN, acid mordant brown G, acid mordant yellow GG, acid complex yellow and other dyes.

c. In pesticide production, salicylic acid is used to synthesize organophosphorus insecticides. It is also used as an intermediate of thiophosphate, methyl issalicylate, isopropyl salicylate and rodenticide.

d. In rubber industry, salicylic acid is used in the production of anti-coke agents, ultraviolet absorbers and blowing agents.

e. In the production of spices, salicylic acid is used to produce methyl salicylate, ethyl salicylate, etc. Methyl salicylate can be used as an oral cleanser, such as toothpaste flavor.

f. In resin industry, as a commonly used epoxy accelerator, salicylic acid has strong catalytic effect and stable performance, which can effectively promote the curing process of epoxy resin and improve its physical properties and chemical stability.

g. In agriculture, salicylic acid is cheap, non-toxic and harmless, convenient to use, and its non-toxic and harmless characteristics are in line with the development trend of modern agriculture, so it can be widely used in agriculture. In addition, salicylic acid can also be used as an added ingredient to make agricultural reagents, such as rooting agents, plant growth regulators, etc. to improve crop yield, quality and resistance, and enhance the competitiveness of agricultural products in the market.
