Morpholine; CAS 110 91 8; Mainly Used in The Manufacture of Rubber Accelerators and Vulcanizers¹

Product Description Product Description Morpholine, also known as 1, 4-oxazepine and diethylenimine oxide, is a kind of colorless alkaline oily liquid. It smells of ammonia and has hygroscopicity. Morpholine could evaporate with water vapor and miscible with water. It is Soluble in acetone, benzene, ether, pentane, methanol, ethanol, carbon tetrachloride, propylene glycol and other organic solvents. Morpholine Vapor could form an explosive mixture with air and the explosion limit is 1.8% to 15.2% (volume fraction). Morpholine is a secondary amine, and at the same time it has the property of inorganic acid and organic acid, so that it can generate salt and amide.Morpholine contains secondary amine groups and it has all the typical reaction characteristics of the secondary amine groups. It can react with inorganic acid to form a salt, and also can react with organic acid to form salt or amide. Morpholine can carry out alkylation reactions and it also carry out ketone reaction or Willgerodt reaction with ethylene oxide. Because of the unique chemical properties of morpholine, it has become one of the important petrochemical products with important commercial application. It can be applied to produce rubber vulcanization accelerators such as NOBS, DTOS and MDS. And it is also applied to produce anti-corrosives, anti-corrosion agents, detergents, detergents, analgesics, local anesthetics, sedatives, respiratory and vascular stimulants, surfactants, optical bleach, fruit preservatives, and textile dyeing auxiliaries. Morpholine also has a wide range of applications in the field of rubber, pharmaceuticals, pesticides, dyes, coatings and other industries. In medication it could be applied in the production of morpholine guanidine, virus Ling, ibuprofen, cough must, naproxen, dichloroaniline, sodium phenylacetate and other important drugs.The two main production method of morpholine are DEA method (diethanolamine method) and DEA method (diethylene glycol method)It is noteworthy that new polymer monomer acrylic morpholine has obtained a rapid development in recent years. Acrylic acid morpholine could be produced from the reaction between acrylic acid and morpholine. And acrylic acid morpholine is a kind of water-soluble monomer, and it is still water-soluble after the polymerization. So it could be applied for the modification of aqueous polymers. Besides, acrylic morpholine is widely used as a reactive diluent for UV curable resins. With the deepening of applied research, many new specific uses have been developed and it becomes polymer monomer with rapid development. Product Parameters Morpholine Chemical PropertiesMelting point -7--5 °C (lit.)Boiling point 126.0-130.0 °C 129 °C (lit.)density 0.996 g/mL at 25 °C (lit.)vapor density 3 (vs air)vapor pressure 31 mm Hg ( 38 °C)refractive index n20/D 1.454(lit.)Fp 96 °Fstorage temp. Store below +30°C.solubility water: misciblepka8.33(at 25oC)form Liquidcolor APHA: ≤15Specific Gravity0.996OdorCharacteristic amine-like odorPH11.2 (H2O)(undiluted)explosive limit1.4-15.2%(V)Water Solubility MISCIBLEFreezingPoint -4.9oCSensitive HygroscopicMerck 14,6277BRN 102549Dielectric constant7.3(25oC)Exposure limitsTLV-TWA 20 ppm (~70 mg/m3) (ACGIH, MSHA, and OSHA); STEL skin 30 ppm (ACGIH); IDLH 8000 ppm.Stability:Stable.
