description of properties: colorless oily liquid. melting point -4.76°c, boiling point 128.3°c (0.8kpa), relative density 1.0005 (20/4°c), refractive index 1.4548, flash point 35°c. miscible with water, acetone, benzene, ethers, alcohols, glycols and oils. it has hygroscopicity and ammonia odor. with water vapor can be volatile. production method: it is obtained by dehydration and cyclization of diethanolamine with sulfuric acid. add diethanolamine into the water reaction pot, add sulfuric acid dropwise below 60°c, after the addition is complete, raise the temperature to 185-195°c, and keep it warm for 30 minutes. cool to below 60°c, add sodium hydroxide solution dropwise to ph = 11, cool, filter, rectify the filtrate, collect fractions below 130°c, the content of refined morpholine can reach more than 99.5%. the raw materials of this method are easy to get, and it has become the main method of producing morpholine in the world. morpholine can be prepared by gas-phase catalytic reaction of dioxane and ammonia. application: mainly used in the production of rubber vulcanization accelerators, also used in surfactants, textile printing and dyeing auxiliaries , medicine, pesticide synthesis. morpholine is also used as a catalyst for the polymerization of butadiene, a corrosion inhibitor, and an optical bleaching agent. this product is also a solvent for dyes, resins, waxes, early glue, and casein. at present, the output of morpholine in the world is 30,000-40,000 t/a. morpholine salts are also widely used, and morpholine hydrochloride (10024-89-2) is an intermediate in organic synthesis; morpholine fatty acid salts can be used as coating agents for fruits or melons and vegetables inhibit radical respiration, prevent water volatilization and epidermal atrophy.
