摘要:
Substituted pyrazole compounds of the formula (1). The compounds are synthesized from a pyrazole derivative and a haloalkyleneoxime ester derivative, and have excellent herbicidal effects. Herbicide compositions containing the substituted pyrazole derivatives or hydrazide derivatives thereof as active ingredients possess wide herbicidal spectra, work sufficiently in small dosages, and are sufficiently safe for certain important crops.

摘要:
A process for preparing a pentaerythritol-tetrakis(3-alkylthio-propionate) represented by the general formula: ##STR1## wherein R represents an alkyl group having from 8 to 30 carbon atoms, is disclosed, comprising reacting an alkylmercaptan having from 8 to 30 carbon atoms with an acrylic ester or an acrylic amide to form a 3-alkylthio-propionic acid ester or a 3-alkylthio-propionic acid amide, hydrolyzing the ester or amide to form a 3-alkylthio-propionic acid, and then reacting this product with pentaerythritol. The desired product can easily be obtained at high purity and high yield by this process.
摘要:
A process for producing 2,3,5,6-tetrachloro-1, 4-benzenedicarboxylic acid, comprising heating 2,3,5,6-tetrachloro-1,4-benzenedicarboxamide together with sulfuric acid exhibiting an acidity function (—Ho) of 10.27 to 14.44 in the presence of water contained in an amount smaller than a stoichiometric value of hydrolysis at 110 to 190° C. This process efficiently produces 2,3,5,6-tetrachloro-1,4-benzenedicarboxylic acid which is a precursor of dimethyl 2,3,5,6-tetrachloro-1,4-benzenedicarboxylate useful as a herbicide.
摘要:
A propionate derivative having the general formula (I): ##STR1## wherein R.sup.1 is phenyl which may be substituted with one or more of the same as different substituents selected from the group consisting of halogen, methyl, methoxy, and nitro, R.sup.2 is alkyl, cycloalkyl, or alkenyl, R.sup.3 is alkylthio, cycloalkylthio, alkenylthio, phenylthio, or benzylthio which may be substituted with halogen or methyl and R.sup.4 is imidazol-1-yl or 1,2,4-triazol-1-yl, or the acid addition salt thereof or the metal complex thereof.This novel propionate derivative is suitable for use as an agricultural fungicide.
