摘要： A process is provided for preparing 2,6-dinitro-N,N-dipropyl-4-(trifluoromethyl)benzenamine from 4-chlorotrifluoromethylbenzene. The process includes a two stage nitration and an amination step. Ethylene dichloride is utilized as a diluent and solvent in the nitration steps. Spent acid from the first nitration is reconstituted with sulfur trioxide for use in the second nitration. Spent acid from the second nitration is used directly in the first nitration and evaporation is used to remove nitrosoamines from the final trifluralin product.

摘要： Dikegulac, its salts and related derivatives are prepared by reacting 2-Keto-L-gulonic acid with 2,2 dimethoxypropane at an elevated temperature in the presence of a catalytic amount of a strong acid. This produces a reaction intermediate which is then reacted with a base to complete hydrolysis and produce an acid salt of dikegulac. Simple concentration and phase separation techniques are used to provide a more efficient, environmentally friendly and cost effective process.

摘要： Disclosed is a process of nitrating or dinitrating an aromatic amine compound that involves reacting the aromatic amine and nitric acid in the presence of acetic acid such that the molar ratio of the aromatic amine compound to acetic acid is from about 1:2 to about 1:16, and the molar ratio of nitric acid to the aromatic amine is between about 1.0 to about 1.5 times the nitric acid needed to complete the reaction. More particularly, the invention is a process of forming Pendimethalin, N-(1-ethylpropyl)-2,6-dinitro-3,4-xylidine, from N-(1-ethylpropyl)-3,4-xylidine (4-NAX) that involves reacting 4-NAX and nitric acid in the presence of acetic acid such that the molar ratio of nitric to the 4-NAX is between about 2:1 and about 3:1, preferably between about 2:1 and about 2.6:1, and such that the molar ratio of 4-NAX to acetic acid is between about 1:2 to about 1:16, preferably between about 1:4 and about 1:8.

摘要： A simple and inexpensive process is described for reducing the concentration of N-nitroso-containing compounds. The process is applicable for compositions comprising N-nitroso-containing compounds and other desired compounds wherein the N-nitroso-containing compounds thermally decompose at a temperature below the decomposition temperature of the desired compounds. For compositions comprising N-nitroso-pendimethalin in Pendimethalin, the process requires heating the mixture to a temperature greater than about 120.degree. C., and holding the Pendimethalin at that temperature for a time effective to decompose the N-nitroso-pendimethalin present in the mixture. Volatile decomposition products are advantageously removed from the composition.
