  4-Methylmorpholine , with CAS number of 109-02-4, can be called N-Methylmorpholine ; Morpholine, N-methyl- ; 4-Methylmorfolin ; 4-Methylmorfolin ; 1-Methylmorpholine . It is a clear liquid with an ammonia-like odor. Less dense than water and insoluble in water. 4-Methylmorpholine (CAS NO.109-02-4) is used as solvents, catalysts, emulsifiers, organic synthesis intermediates, and also can be used as solvents, catalysts, emulsifiers, organic synthesis intermediates, besides used for the extraction solvent, chlorine stabilizer hydrocarbons, corrosion inhibitors, catalysts drug production.  4-Methylmorpholine (CAS NO.109-02-4) is a moderately toxic substance, flammably, burning will produce toxic fumes of nitrogen oxides, so it needed to store in the cold and dry environment and stored separately with oxidants and acids. Dry powder, dry sand, carbon dioxide, foam can be used if something urgent happened.
