| Application | N,N-dibutylformamide is a formamide compound. N-formylated amine compounds have a wide range of applications in the fields of chemical engineering and pharmaceutical production. For example, formamide can be used as a raw material for organic synthesis, a paper treatment agent, a softener for fiber industry, a softener for animal glue, and an analytical reagent for determining the amino acid content in rice. At the same time, formamide is also an excellent organic solvent, can be used for the separation of chlorosilane, purification of oil and fat; In addition, formamide has active reactivity, can occur a variety of reactions, in addition to the three hydrogen reaction, can also be dehydration, CO removal, reactions such as the introduction of an amino group, an acyl group, and the occurrence of a ring. |
| preparation | in a glove box, add catalyst Rh/I(16.5mg), N-methylpyrrolidone (1.0mL), di-N-butylamine (168 μL,1mmol) and decane (10 μL,0.05mmol). Then, the CO2 displacement vessel was filled with nitrogen three times, and CO2(20ATM) and H2(20atm) were further filled, and the reaction was stirred in an oil bath at 100 ° C. For 24 hours. After completion of the reaction, the reaction kettle was cooled to room temperature with an ice-water bath, and the gas was slowly discharged. The supernatant was centrifuged and the gas phase was measured. The yield was 68%. |
