background | the scientific name of salicylamide is 2-hydroxybenzoformamide, which is a very important organic synthesis intermediate and is a raw material for the synthesis of many important derivatives (such as spironcide nitroaniline, analgesic and antiheat, etc.). It is widely used in medicine, spices, dyes, many fields of rubber additives. Salicylamide is not only an important fine chemical intermediate, but also a widely accepted and widely used antipyretic analgesic sub, used for fever, headache, neuralgia, arthralgia and or active rheumatism, etc. |
application | salicylamide is a widely used fine chemical intermediate. it can be used to synthesize organic chemicals such as nifediamine and o-ethoxyformamide, and is also commonly used in the fields of medical treatment, perfume, fuel and rubber additives, at the same time, salicylamide is a widely used antipyretic analgesic, which can be used to treat fever, headache, neuralgia, joint pain and rheumatic joint pain. |
preparation | a preparation method of salicylamide, adding 150kg of methyl salicylate and 420kg of toluene to a 1000-liter stainless steel reactor, heating to 40-45 ℃, continuously passing ammonia for ammonification reaction, and controlling the reaction temperature at 40-45 ℃, the reaction pressure is controlled at 0.25~0.35MPa, ammonia gas is stopped after ammoniation reaction for 5 hours, toluene and reaction by-product methanol are heated and recovered, the remaining material is cooled to 20 ℃, salicylamide is obtained after crystallization and centrifugation, and the yield is 97.8%. |
chemical properties | white or micronized red crystalline powder. Melting point 140 ℃. Easily soluble in hot water, alcohol, ether and chloroform, slightly soluble in cold water. The pH of saturated aqueous solution at 28 ℃ is about 5. Slightly bitter. |
use | antipyretic analgesic for fever, headache, neuralgia, arthralgia, active rheumatism and other diseases when used for antipyretic analgesia, adults 0.3~0.5g, 3~4 times a day. When used for anti-inflammatory, 1~2g, once every 4~6 hours, 3~6 days as a course of treatment. |
production method | this product has certain antipyretic, analgesic and anti-inflammatory effects, but its curative effect is worse than aspirin. It does not decompose in the stomach and has little irritation to the stomach. Suitable for fever, headache, neuralgia, arthralgia and active rheumatism. |
