Abstract:
DERIVATIVES OF P-CARBAMOYLAMINO-PHENOXYCARBOXYLIC ACIDS SUCH AS SALTS, ESTER OR AMIDES ARE VERY EFFECTIVE IN PLANT-INFLUENCING, AS SELECTIVE HERBICIDES, DEFOLIDANTS OR GROWTH REGULATORS. THEY MAY BE USED IN PESTICIDAL PREPARATIONS.
Abstract:
N-acyl-3,4-dihydro-oxazine-(1,3)-derivatives of the formula IN WHICH A represents a sulphur or an oxygen atom, R1 indicates a six-membered ring condensed with the dihydro-oxazine ring and R2 represents an aliphatic or aromatic residue are very effective compounds for controlling plantpathogenic fungi.
Abstract:
The invention provides a new process for preparation of aryloxazoles by ring closure reaction between an o-hydroxy-amino benzene and a carboxylic acid. The improvement over known processes consists in performing the reaction in a two-step heating procedure and in the presence of small amounts of specific amines, preferably non-aromatic cyclic nitrogen bases, having a Pk-value of at least 7. The reaction products are valuable optical whitening agents.
Abstract:
It has been found that cycloalkyl carboxylic acid esters of the general formula WHEREIN N DENOTES ONE OF THE NUMBERS 1, 2 OR 3, Y represents oxygen or sulphur and R1, R2, R3, R4 and R5 each represents hydrogen or various substituents possess biocidal activity, preferably for combatting weeds, members of the class Arachnoidea and bacteria and fungi.
Abstract:
PHOTOGRAPHIC MATERIAL, PREFERABLY FOR THE SILVER DYESTUFF BLEACHING METHOD, IS PROVIDED WHICH CONTAINS IN AT LEAST ONE GELATINE-CONTAINING LAYER AS A WETTING AGENT A WATERSOLUBLE, SURFACE-ACTIVE PERFLUORO COMPOUND. WITH THESE WETTING AGENTS A VERY GOOD UNIFORMITY OF THE APPLIED GELATINE LAYERS IS ACHIEVED.
WHEREIN Y DENOTES AN ALKYLENE CHAIN OF UP TO 6 CARBON ATOMS WHICH MAY BE INTERRUPTED BY A HETERO-ATOM SELECTED FROM THE GROUP CONSISTING OF NITROGEN, OXYGEN OR SULFUR, A DENOTES AMINO OR LOWER ALKYLAMINO, B DENOTES HYDROGEN, LOWER ALKYL, LOWER ALKOXY OR PHENYL, Z DENOTES AN AMINO, HYDRAZINO OR ETHERIFIED HYDROZYLAMINO GROUP WHICH MAY BE QUATERNIZED, AND D1 IS THE RESIDUE OF A DIAZO COMPONENT; THE NEW DYESTUFFS ARE ESPECIALLY VALUABLE FOR DYEING SYNTHETIC FIBERS SUCH AS POLYVINYLCHLORIDE, POLYAMIDE OR POLYURETHANE WITH GOOD GENERAL FASTNESS PROPERTIES, SUCH AS FASTNESS TO LIGHT, WASHING AND SUBLIMATION.
Abstract:
A process for printing synthetic nitrogenous fibers with dyestuff that are soluble or dispersible in water is disclosed. The fibers to be printed are pretreated with an aqueous preparation consisting substantially of at least one fiber, substantive water-soluble, anionic resist for synthetic polyamide fibers selected from the group consisting of polycondensates of diarylsulfones containing at least one phenolic hydroxy group with formaldehyde. The fibers so pretreated are then dried and then printed with the printing paste containing the dyestuff.
Abstract:
It is known to coat plastics materials, especially thermoplastics such as ABS, with metal by electrodeposition, typically with chromium on top of nickel. Conventional methods are often unsatisfactory when applied to thermosetting resinbased articles, the metal coating peeling or flaking off when the articles are subjected to repeated changes in temperature. It has now been found that copper or nickel coatings adhere well to surfaces, prepared in a conventional manner, of thermosetting plastics as well as of thermoplasts, provided that the coatings are electrodeposited in a manner such that they have an average stress in tension of at least 2,000 kg./sq. cm. E.g., a molding prepared from ''''Araldite'''' MY 750, HT 972, calcined china clay and glass fibers, is prepared for electroplating by A. ETCHING WITH CHROMIC ACID B. DEPOSITING A FILM OF PALLADIUM THROUGH TREATMENT WITH STANNOUS CHLORIDE AND PALLADIUM CHLORIDE SOLUTIONS C. DEPOSITING A FILM OF COPPER OR NICKEL BY REDUCTION OF COPPER SULPHATE OR NICKEL SULPHATE SOLUTIONS. Next, a nickel coating is electrodeposited under conditions such that it had an average stress in tension of 2,440 to 6,460 kg./sq. cm.: this coating being dull, a bright, lightly stressed nickel coating was electrodeposited before the final layer, of chromium, was applied.
