Abstract: Disclosed is a process for producing 4-amino-3-fluorobenzotrifluoride which comprises reacting 3,4-difluorobenzotrifluoride with anhydrous ammonia (liquid ammonia or gaseous ammonia) under pressure.

Abstract: A method of enhancing the quality of fruits and vegetables grown on trees and/or on plants by covering a substantial portion of the soil surrounding the plant or tree with a spunbonded nonwoven film-fibril sheet material that has been produced by a flash-spinning process. Preferably, the sheet comprises a plexifilamentary film-fibril sheet fabricated from a polyolefin such as polyethylene or polypropylene. When the spunbonded nonwoven film-fibril sheet material is used in this manner, it unexpectedly enhances fruit quality by providing excellent water resistance, moisture vapor permeability and air permeability.

Abstract: A compound of the formula [I] and pharmaceutically acceptable salts thereof; and a synthetic intermediate represented by the formula [II] and pharmaceutically acceptable salts thereof, ##STR1## wherein R 1 is hydrogen or lower alkyl;R 2 is hydrogen or a protective group of thiol;R 3 is hydroxy, a remainder of ester group or a remainder of amido group;A is straight or branched lower alkylene, andthe sulfur atom in the side chain may be directly join with --CO-- to conform a thiolactone ring.The compounds of this invention have excellent thymulin-like activities and are expected to be useful for treatment of various immune disorders such as immunodeficiency and autoimmune diseases.

Abstract: The novel compounds of formula ##STR1## wherein n and R are as defined in claim 1, are very suitable for use as UV absorbers in layers of photographic materials.

Abstract: The invention relates to novel substituted N-benzoyl-N'-3,5-dichlorohexafluoropropyloxyphenylureas of the formula ##STR1## wherein R.sub.1 is hydrogen or fluorine and R.sub.2 is fluorine or chlorine, and to salts thereof; to processes and intermediates for the preparation of these compounds and to compositions containing the novel compounds for controlling insects, representatives of the order Acarina and slugs and snails, in particular plant-destructive insects.

Abstract: Novel naphthyridine-carboxylic acids as antibacterial agents are described as well as methods for their manufacture, formulation, and use in treating bacterial infections.

Abstract: Azo dyestuffs of the formula ##STR1## having the substituent meanings given in the description, are outstandingly suitable for dyeing and printing materials containing hydroxyl groups and amide groups.

Abstract: The invention relates to N-acyl-aminoalkyl-2-hydroxyethylsulfides of formula R--CONH--(CH.sub.2).sub.n --S--CH.sub.2 --CH.sub.2 --OH, where R is a hydrogen atom or a (C.sub.1 -C.sub.4) alkyl group and n is an integer between 3 and 6, and to a method for preparing them. The method consists in reacting compounds of formula R--CONH--(CH.sub.2).sub.m --CH.dbd.CH.sub.2, where R has the above-mentioned meaning and m is an integer between 1 and 4, with the equivalent quantity of mercaptoethanol at approximately 15.degree. to approximately 150.degree. C. in the presence of a radical starter and in the presence or in the absence of a solvent which is inert to the reactants and to radical reactions.

Abstract: It has been discovered that AAL-toxin, a known host-specific phytotoxin produced by Alternaria alternate f. Sp. lycopersici, has a broad range as a pre-emergent or post-emergent bioherbicide. A method using AAL-toxin has been developed for controlling certain weeds, including duckweeds, jimsonweed, black nightshade, prickly sida, redroot pigweed and northern jointvetch. This phytotoxin can be used pure, as a cell-free filtrate, a crude filtrate, or a crude suspension of the culture.

Abstract: A novel disulfide compound is presented which can be readily led to 5-amino-2-chloro-4-fluoro-thiophenol in good yield.
