Claims
- 1. A process for producing N-alkyl-nitroaniline comprising:
- (a) reacting a nitrophenol of the formula: ##STR2## wherein R is CF.sub.3, and wherein R' is selected from the group consisting of hydrogen, nitro and CF.sub.3, with an alkylating compound selected from the group consisting of ethylene oxide, propylene oxide, styrene oxide, and mixtures thereof, to form an intermediate product and
- (b) reacting said intermediate product with an amine selected from the group consisting of methylamine, ethylamine, isopropylamine, propylamine, butylamine, and mixtures thereof, to produce said N-alkyl-nitroaniline.
- 2. The process of claim 1 wherein the nitrophenol is present in an amount of from about 1 to about 50 mole percent, the allylating compound is present in an amount of from about 50 to about 99 mole percent and the amine is present in an amount of from about 1 to about 99 mole percent, based on the molar amount of the phenol.
- 3. The process of claim 1 wherein steps (a) and (b) are carried out in an enclosed reactor and wherein step (a) is carried out at autogeneous pressure and step (b) is carried out at a pressure of from about 1 to about 5 atmospheres.
- 4. The process of claim 1 wherein step (a) is carried out at autogeneous pressure in an enclosed reactor and step (b) is carried out at atmospheric pressure in an open reactor.
- 5. The process of claim 1 wherein step (a) is carried out at a temperature of from about 0.degree. C. to about 300.degree. C. and step (b) is carried out at a temperature of from about -20.degree. C. to about 200.degree. C.
- 6. The process of claim 5 wherein the temperature for step (a) is from about 100.degree. C. to about 200.degree. C. and the temperatures from step (b) is from about 25.degree. C. to about 75.degree. C.
- 7. The process of claim 1 wherein the nitrophenol is 4-tert-butyl-2,6-dinitrophenol and the amine is secondary butylamine.
