摘要:
Ectoparasitic insect pest controllers for animals, containing hydrazine derivatives of the general formula (I) as the active ingredient, and methods for application of the same: (I) [wherein A is (II), (III), (IV), (V) (wherein R4 and R5 are each H, C1-6 alkyl, or the like; and X is H, or one to five substituents selected from among halogeno and optionally halogenated C1-6 alkyl groups); R1 is H or C1-6 alkyl; R2 and R3 are each H, OH, C1-6 alkyl, phenylcarbonyl, or the like; Y is H, or one to five substituents selected from among halogeno, nitro, and cyano; Z is halogeno, cyano, C1-6 alkyl, or the like; and W is O or S]. The insect pest controllers exert remarkable controlling effects on parasitic insect pests harmful to domestic or pet animals, e.g. fleas, lice, ticks.

摘要:
A process is described for the activation of zeolitic catalysts containing titanium having the formula: xTiO2(1-x)SiO2 wherein x ranges from 0.0001 to 0.4, which consists in treating said materials with a solution of an ammonium salt of a carboxylic acid and subsequently subjecting them to calcination. The catalysts thus treated have higher catalytic performances with respect to those not treated, in oxidation processes of organic substrates.
摘要:
The invention relates to a purification method of cyclohexanone-oxime in a solution of solvents immiscible with water, which consists in washing said solutions with water or with an aqueous solution of a base having a pK
摘要:
Process for the production of cyclohexanone oxime in which a phosphate-containing aqueous reaction medium is cycled from a hydroxylammonium synthesis zone to a cyclohexanone oxime synthesis zone and back to the hydroxylammonium synthesis zone, in which hydroxylammonium synthesis zone hydroxylammonium is formed by catalytic reduction of nitrate with hydrogen, and in which cyclohexanone oxime synthesis zone hydroxylammonium is reacted with cyclohexanone to form cyclohexanone oxime, wherein the phosphate concentration in the acqueous reaction medium entering the cyclohexanone oxime synthesis zone is higher than 3.0 mol/l.
摘要:
The present invention relates to compounds of formula (I) and derivatives thereof, in which the variables are as defined in the claims, their synthesis, and their use as estrogen receptor modulators.

摘要:
Compounds of the formula 1 where the symbols have the meaning described in the application, have retinoid-like or retinoid antagonist-like biological activity.
摘要:
The present invention relates to a method of producing a taxane-type diterpene wherein a cell and/or a tissue of a plant which produces the taxane-type diterpene is cultured in the presence of at least one substance selected from the group consisting of coronatines, a bacterium which produces the coronatines, a culture solution or a culture extract of such bacterium, cyclic polysaccharides, fatty acids, and an imino or amino derivative of jasmonic acids, then the taxane-type diterpene is recovered from the resulting cultures.
摘要:
In the process for the preparation of vinyloxime ethers of the formula I by reacting an oxime with an alkyne where R1 and R2 are identical or different and are alkyl or aryl radicals, R3 is hydrogen, an alkyl or aryl radical, and R4 is a radical having the meaning of R3, which may be different than R3, or is a hydroxyalkyl radical, in a superbasic polar organic solvent in the presence of a strong base, the reaction is carried out under conditions such that the resulting vinyloxime ether stays in contact with the other constituents of the reaction mixture for only a short time so that it is unable to decompose or react to give secondary products to a significant extent.
