Abstract: In accordance with the sought-after features of an improved process for the preparation of Dimilin, there is provided herein a process which comprises first extracting 2,6-difluorobenzamide from an aqueous acid solution with a selective solvent which is acid-stable and water-insoluble. The extract then is condensed in situ with p-chlorophenyl isocyanate at an elevated temperature to form the desired product. The selective solvent preferably has a boiling point at the reaction temperature, preferably about 120.degree.-170.degree. C. Finally, the product is crystallized from the selective solvent.

Abstract: Mononitrotrifluoromethyl diphenylethers having the formula: ##STR1## ARE PREPARED BY REACTING A CHLORONITROTRIFLUOROMETHYLBENZENE WITH A PHENOLATE.The compounds of the invention show good fungicidal and post-emergence herbicidal activity.

Abstract: A drive system for a multi-mode reproducing apparatus preferably of the electrostatographic type. The drive system is adapted to selectively drive sub-systems of the apparatus at a plurality of speeds. The drive system can be utilized to drive a document feeding apparatus for moving original exposure or to provide relative movement between a document and a suitable viewing system. The apparatus preferably features an automatic conditioning system which resets the drive system to a base output speed after it has finished operation at a speed other than the base speed.

Abstract: Fungicidal 3-amino-6-trifluoromethyl-2,4-dinitrodiphenylethers having the formula: ##STR1## where R is H or lower alkyl,X is halogen,n is 0, 1, 2 or 3, andR.sub.1 and R.sub.2 are selected from H and lower alkyl, or form a piperidinyl, morpholinyl, or pyrrolidinyl ring structure,Are prepared by two-step process involving reaction of 2,4-dichloro-3,5-dinitrotrifluoromethylbenzene with an amine, and condensation of the intermediate with a phenol.The compounds of the invention show good fungicidal activity against bean mildew, bean rust and tomato blight, and insecticidal activity against Mexican bean beetle.

Abstract: Insecticidal N-acyl-N-(N'-methylenepyrrolidonyl)dialkylanilines having the formula: ##STR1## where R.sub.1 and R.sub.2 are both lower alkyl, and R is alkyl, alkenyl or haloalkenyl.Are prepared by two-step process involving reaction of 2,5-dialkylaniline with N-methylolpyrrolidone followed by acylation.The compounds of the present invention show good insecticidal activity against the Mexican bean beetle.

Abstract: In accordance with the present invention, there is provided herein a cyclic, two-stage process for dinitrating 4-chlorobenzotrifluoride to form 4-chloro-3,5-dinitrobenzotrifluoride in high yield. The process commences with a mononitration stage wherein 4-chlorobenzotrifluoride is substantially completely converted to 4-chloro-3-nitrobenzotrifluoride (the "monoitro" compound) in the presence of a nitric acid, sulfur trioxide and sulfuric acid mixture. The used acid mixture then is diluted with water to form an aqueous used acid layer in which the solubility of the mononitro compound is negligible and a mononitro layer. The aqueous used acid layer then is separated from the mononitro layer and discarded. The mononitro compound thereafter is further nitrated in a dinitration stage in the presence of a fresh nitric acid, sulfur trioxide and sulfuric acid mixture.

Abstract: Fungicidal 2,6-dinitrodiphenylthioethers having the formula: ##STR1## WHERE X is halogen, R is halogen or methyl substituted at the 2', 4' or 5' positions, n is 0-3.The compounds are particularly useful against bean rust and bean mildew.

Abstract: The present invention provides herbicidal-N-(3-amino 2,4-dinitro-6-trifluoromethylphenyl)-pyrrolidones having the formula: ##STR1## where X is oxygen or sulfur, and R, R.sub.1 and R.sub.2 are selected from among H or lower alkyl, of up to 4 carbon atoms.The compounds of this invention are prepared by reacting a 2,4-dihalo-3,5-dinitrobenzotrifluoride with an amine, followed by condensation of the amino intermediate with the alkali metal salt of a pyrrolidone.The N-(substituted-phenyl)-pyrrolidones described herein show good herbicidal activity, particularly pre-emergence activity against Japanese millet and crabgrass.
