In a process for the production of 2-nitrobutylmorpholine from 1-nitropropane, morpholine and formaldehyde the improvement comprising mixing 1-nitropropane and morpholine, heating to about 55-60.degree. C., adding formaldehyde over about a 3-4 hour period, holding the reaction mixture at about 55-60.degree. C. for about a 2-3 hour period to make a total addition/holding period of at least six hours, cooling the reacton mixture to form a two phase oil/aqueous system and concentrating the oil layer to 2-nitrobutylmorpholine by removing excess water and 1-nitropropane.

Process for the production of 2-nitrobutylmorpholine

An improvement in the process for the production of P-1487 from the reaction of 1-nitropropane, 37% formaldehyde and morpholine, the improvement comprising mixing 1-nitropropane and 37% formaldehyde at a temperature of 40.degree.-42.degree. C., adding morpholine maintaining the temperature at 40.degree.-42.degree. C., holding the mixture for two hours at 40.degree.-42.degree. C., cooling to allow layer separation, separating the upper oil layer and concentrating the oil layer to P-1487 by removing excess water.
