Reaction Conditions:

with water at 160 - 190; under 9000.9 Torr; for 3.41667 h;Autoclave;

Steps:

4 Example 4: Preparation of N,N-Dibutylformamide
85% of formic acid, 170.5g (ie, 25.5g of water) and 99% of dibutylamine, 391g, were added to a 1-litre high-pressure reactor and the stirrer was turned on to obtain a homogenous reaction. system. The molar ratio of formic acid to butanediamine is 1.05:1.While maintaining stirring, the homogeneous reaction system was heated to about 160° C. After about 55 minutes of incubation, the temperature was raised to about 190° C., and the pressure in the autoclave increased to about 1.2 MPa. Continue to rise, basically maintaining stability, maintaining the reaction for about 2.5 hours, emptying and draining off the carbon monoxide and water vapor in the autoclave.The reaction product was collected to give about 557 g of a uniform and transparent solution.
