    摘要: An organic polysilane, which can produce signals respectively derived from a Si—O bond, an alkoxy group and a hydroxy group at levels equal to or lower than the detection limits in 29Si and 13C CP/MAS NMR analysis, can be produced by a method which includes: polymerizing an organic dihalosilane in an aprotic solvent in the presence of an alkali metal and/or an alkali earth metal to produce a mixture containing an organic polysilane having a terminal halogeno group; adding a solution containing an organic lithium compound and an aprotic polar solvent to the mixture to inactivate the organic polysilane having the terminal halogeno group; and then adding a protic polar solvent to the resultant mixture to deactivate the alkali metal and/or the alkali earth metal.

    摘要: Provided is a pyribencarb aqueous suspension agrochemical composition which contains an adjuvant for reinforcing the efficacy of pyribencarb, and which is capable of preventing a pharmaceutical preparation from becoming highly viscous or solidified and capable of providing a sufficient controlling effect with a small amount of pyribencarb. The aqueous suspension agrochemical composition includes: pyribencarb which is an agrochemically active component; an adjuvant for pyribencarb, which is one or more compounds selected from polyoxyalkylene siloxanes, polyoxyethylene/polyoxypropylene block copolymers, and polyoxyalkylene alkyl ethers; a nonionic-anionic surfactant which is a polyoxyalkylene aryl ether sulfuric acid salt and/or a polyoxyalkylene aryl ether phosphoric acid salt; and water.

    摘要: The present invention provides a method for producing agrochemical granules, which contain an agrochemical active ingredient, one or more kinds of hydrophobic substances, and a substance capable of absorbing oil, with stable quality. The method for producing agrochemical granules of the present invention includes (i) a step of obtaining a mixture by mixing an agrochemical active ingredient, one or more kinds of hydrophobic substances, and a substance capable of absorbing oil together, (ii) a step of obtaining a kneaded material by loading the obtained mixture into a kneading device, kneading the mixture at a heating temperature equal to or higher than the highest melting point of the hydrophobic substances, and then causing the kneaded material to be discharged from the kneading device at a temperature equal to or lower than the highest melting point of the hydrophobic substances, and (iii) a step of granulating the obtained kneaded material by an extrusion molding method.
