Morpholine contains secondary amine group, which has all the typical reaction characteristics of secondary amine group. It can react with inorganic acid to form salt, and react with organic acid to form salt or amide. It can also react with ethylene oxide, ketone or willgerodt. Due to its unique chemical properties, morpholine has become one of the most important commercial fine petrochemical products. It can be used to prepare nobs, DTOs, MDS and other rubber vulcanization accelerators, rust inhibitors, corrosion inhibitors, cleaners, detergents, painkillers, local anesthetics, tranquilizers, respiratory and vascular stimulants, surface activators, optical bleaching agents Fruit preservatives, textile printing and dyeing auxiliaries, etc., are widely used in rubber, medicine, pesticides, dyes, coatings and other industries. In medicine, they are used in the production of morpholine guanidine, ribavirin, ibuprofen, ketamine, naproxen, dichloroaniline, sodium phenylacetate and other important drugs.
