n-methylmorpholine

N-Methylmorpholine is an organic compound with the molecular formula C5H11NO, a colorless liquid with an ammonia smell and sensitive to air; it can be mixed with water and ethanol , benzene and ether are miscible; flammable, corrosive, slightly toxic, and irritating odor, inhalation of steam is irritating to skin and mucous membranes, LD50 1970mg/kg. N-methylmorpholine is a heterocyclic tertiary amine and an important fine chemical raw material. It can be used as a catalyst for the production of polyurethane foam, a catalyst for pharmaceutical synthesis and organic synthesis, and can also be used for the synthesis of medicines, pesticides, surface Fine chemical products such as active agents, emulsifiers, and corrosion inhibitors can also be used as solvents, extractants, and curing agents for polyurethane coatings.

N-methylmorpholine is an organic compound with the chemical formula O(CH2CH2)2NCH3. It is a colorless liquid. It is a cyclic tertiary amine. It is used as a base catalyst for polyurethane formation and other reactions. From the reaction of methylamine and diethylene glycol, N-formylmorpholine hydrogenolysis derived. It is the precursor of N-methylmorpholine N-oxide, a commercially important oxidizing agent.

N-Methylmorpholine is a flammable liquid with a flash point of 125 °F (52 °C). It has a vapor pressure of 0.1 mm Hg at 25 °C. N-methylmorpholine is a weak base with a pKa of 7.38. Soluble in water, ethanol and ether.

N-methylmorpholine is used as a base catalyst in polyurethane production. It is also used as a solvent for cellulose and other organic compounds. N-methylmorpholine is also used as a corrosion inhibitor and stabilizer for polymers.

N-methylmorpholine is a harmful substance. It is a skin and eye irritant. It is also a respiratory irritant. N-Methylmorpholine is a suspected carcinogen.

N-Methylmorpholine should be handled with care. It should be stored in a cool and dry place, away from heat and ignition sources. It should be kept in an airtight container and should not be mixed with other chemicals without consulting the safety data sheet.
