Product Application of Morpholine CAS#110-91-8

It is mainly used in the production of rubber vulcanization accelerators, and is also used in the synthesis of surfactants, textile printing and dyeing auxiliaries, medicines, and pesticides. Morpholine is also used as a catalyst for the polymerization of butadiene, a corrosion inhibitor, and an optical bleach. It is also a solvent for dyes, resins, waxes, early rubbers, casein, etc. At present, the world's morpholine production is 30,000-40,000 tons/a. Morpholine salts are also widely used. Morpholine hydrochloride (10024-89-2) and other intermediates are organic synthesis; Morpholine fatty acid salts can be used as coating agents for the epidermis of fruits or melons and vegetables, which can appropriately inhibit the respiration of the base, prevent the volatilization of water and the shrinkage of the epidermis.
