Abstract:
Preparation of fluoroxy-halo-compounds by direct reaction between fluorine and organic compounds having a molecular structure in which at least one oxygen atom is directly bound to a carbon atom in the carbonylic form, in the presence of a fluorination catalyst, in gaseous phase, at an absolute pressure of between 50 and 800 kPa and at a temperature between -5.degree. and +100.degree. C., under conditions of a continuous feeding of the reactants and a continuous removal of the reaction product.
Abstract:
Aromatic ketones or .alpha.-diketones can be prepared from the corresponding carbinols by reaction with molar amounts of a sulfonyl chloride in the presence of a base. The corresponding sulfinic acid or salt thereof with the base is formed simultaneously.
Abstract:
Substituted acrylates of the general formula ##STR1## where R.sup.1 and R.sub.2 are alkyl, alkenyl or alkynyl, X is hydrogen, halogen, alkyl, alkoxy, tirfluoromethyl, cyano or nitro, Y is ethylene, ethenylene, methyleneoxy, oxymethylene, thiomethylene, methylenethio or oxygen, R is hydrogen, substituted or unsubstituted alkyl, cycloalkyl, alkenyl, cycloalkenyl, alkynyl or cycloalkynyl, and fungicides containing these compounds.
Abstract:
The invention relates to a process for extracting nitrohydroxyaromatics from aqueous solutions. In this process, the extracting agent used is an amine salt which comprises an aliphatic amine having a total carbon number of 10 to 75 and a strong acid. The amine salt can be employed undiluted or diluted with an organic solvent.
Abstract:
Optionally substituted 2-benzyl-toluenes can be prepared by reaction of optionally substituted 2-benzyl-tert.-alkyl-toluenes with an optionally substituted aromatic hydrocarbon in the presence of anhydrous iron-(III) halide. The reaction is carried out at ambient to elevated temperature. The optionally substituted aromatic hydrocarbon is employed in molar excess, relative to the 2-benzly-tert.-alkyl-toluenes.
Abstract:
Alkylidene compounds and arylidene compounds are prepared by reacting the corresponding CH-acidic compounds with carbonyl compounds in the presence of a catalyst comprising a metal compound of a metal of Groups IIA, IIIA, IVA, IB, IIB, VIB, VIIB, or VIIIB of the periodic table of elements. The rate of reaction is increased by adding 1 to 40% water referred to the weight of catalyst used.
Abstract:
Compounds of formula ##STR1## in which n denotes an integer from 1 to 10 and X and Y, which are identical or different, each denote an electron-attracting group, are made by reacting a halogenating agent with a compound of formula ##STR2## in which R, X and Y are as hereinbefore defined, anionized by a base.
Abstract:
Mono- and bis-hypofluorites respectively of formula: FO.sub.2 S--R.sub.f --CF.sub.2 OF and FOCF.sub.2 --R'.sub.f --CF.sub.2 OF wherein R.sub.f is perfluoroalkylene or perfluorochloroalkylene and R'.sub.f is a perfluoroalkylene or perfluorooxyalkylene, and process for preparing them, which is conducted continuously, at a temperature from 0.degree. to 60.degree. C. and comprises starting from the respective acyl fluorides ##STR1## by reaction of fluorine in the gas phase in the presence of a catalyst consisting of K, Rb, Cs or Ba fluoride, preferably supported on a metal material.
Abstract:
Optically active enantiomers of alkyl .alpha.-phenoxypropionates, and of derivatives thereof, can be racemized in good yields and without formation of decomposition products with the aid of an alkali metal (C.sub.1 -C.sub.5) alcoholate, an alkali metal hydroquinone, an alkali metal phenolate or an alkali metal hydroxyphenoxypropionate, or derivatives thereof.
