    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 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： A device for protecting sensitive electronic equipment from low level signal lines short circuited to high voltage power sources includes a switch that open the circuit between the data lines and the sensitive computing equipment if a high voltage condition is detected on the data lines. Otherwise, the switch remains closed and data can be transmitted to the computing equipment.

    摘要： An obturator for measuring incident light in a remote situs such as a body cavity which includes a treatment tubular member through which light is delivered to the remote situs and one or more auxiliary tubular members through which incident light in the remote situs is transmitted to an external light detector. The treatment and auxiliary tubular members are attached to a connector element which is in turn connected to a cystoscope lens port. The treatment and auxiliary tubular members are aligned off-center with respect to the central axis of the obturator so that a cystoscope lens can be inserted in the lens port and pass through the axial center of the obturator. Each auxiliary tubular member receives incident light from a different portion of the remote situs. The apparatus is particularly useful for conducting phototherapy in body cavities and has been demonstrated in the phototherapy treatment of superficial cancer in the bladder.
