Chemical properties It is colorless water-absorbing oily liquid and it smells ammonia. It is soluble in water and methanol, ethanol, benzene, acetone, ether, ethylene glycol and other commonly used solvents.
Uses (1) For medicine, it used as the raw materials for rubber accelerator and fluorescent whitening agent.
(2) Morpholine is the intermediates of fungicide dimethomorph and flumorpholine and organophosphate insecticide phosalphos.
(3) Morpholine is Mainly used for the production of rubber vulcanization accelerator, but also for surfactant, textile auxiliaries, pharmaceuticals, pesticide synthesis. (4) Morpholine also used as a catalyst for polymerization of butadiene, corrosion inhibitors, optical bleach, the goods are dyes, resins, wax, early glue, casein and other solvents. At present, the total production of morpholine in the world is 3-4 million t/a.
(5) Morpholine salts are also widely used. Morpholine salts like morpholine hydrochloride (10024-89-2) are the organic synthesis of intermediates. Morpholine fatty acid salt can be used as the coating agent of fruits or vegetables epidermal coating agent, and it could inhibit the base respiration and prevent the epidermis from evaporation of water and epidermal atrophy.
(6) Morpholine is the main raw materials of accelerator NOBS. for analysis reagents and resins, wax, shellac and other solvents, used in the production of sodium sulfate. Water glass and ultramarine. Also used in the manufacture of glass. Paper. Detergent. Soap. Dye. Synthetic fiber. Tanning. Medicine and ceramics industries. Analysis reagents, such as nitrogen determination, dehydrating agent.
(7) Morpholine is used for the analysis of reagents and resins, wax, casein, shellac and a variety of solvents solvent.
(8) Morpholine could produce salt after reacting with inorganic acid, and it also could produce salt or amide after reacting with organic acid. It also can be alkylated, and it also could come up a ketone reaction or Willgerodt reaction with ethylene oxide.
