摘要:
An amide compound given by formula [I]: wherein R1 represents a C1-C10 haloalkyl and so on, R2 represents a hydrogen and so on, X represents an oxygen or sulfur, Y represents an oxygen or sulfur, Ar represents an aromatic group, A represents an ethylene and so on, and Z1 and Z2 represent alkyl, alkoxy and so on, and a fungicide containing it as an active ingredient.
摘要:
A 2,6-dichlorophenol compound of formula (1): wherein R represents a 3,3-dihalo-2-propenyl group or a benzyl group optionally substituted by halogen atom(s), can be produced by making a phenol compound of formula (2): wherein R has the same meaning mentioned above, react with sulfuryl chloride in the presence of a secondary amine in high yield. The obtained 2,6-dichlorophenol compound of formula (1) is useful as intermediate for producing dihalopropene compounds having insecticidal/acaricidal activity.
摘要:
A production method of an ether compound given by formula (3): which comprises making an alcohol compound given by formula (4): wherein R1 represents a 3,3-dihalo-2-propenyl group or a benzyl group optionally substituted with a halogen atom(s), react with a pyridine compound given by formula (5): wherein R2 represents a hydrogen atom or halogen atom, in a hydrocarbon compound in the presence of an alkali hydroxide or alkaline earth hydroxide with distilling off water from the reaction mixture, provides the ether compound, which is useful as an active ingredient of insecticide/acaricide or production intermediate thereof, in high yield.
摘要:
Disclosed are a method of solidifying a low-boiling-point hydrocarbon, wherein the low-boiling-point hydrocarbon (including hydrocarbons which are gaseous at ordinary temperature) is brought into contact with a metal salt of an aliphatic carboxylic acid, and if necessary a high-boiling-point hydrocarbon, suspended in water, to form a solid aggregate substance, a method of handling the low-boiling-point hydrocarbon, wherein the solid aggregate substance is stored or transported, and a method of regenerating the low-boiling-point hydrocarbon, wherein the solid aggregate substance is decomposed by opening or heating, to obtain the low-boiling-point hydrocarbon. According to the methods, a wide variety of gaseous and highly volatile liquid hydrocarbons can be safely and easily solidified without using harmful reagent, and during storage, transportation, etc., the gaseous hydrocarbons and highly volatile liquids can be handled as a solid material. Further, by releasing under atmospheric pressure at room temperature or by heating if necessary, the original hydrocarbons can be easily obtained.
摘要:
A stand-by mode setting/releasing device is provided for a video cassette recorder (VCR). When the attachment of the video cassette to a video cassette recorder (VCR) is terminated, a microcomputer drives a cylinder motor immediately to execute tape loading. In the stop state, with the tape loading completed, cylinder rotation is continued for 5 minutes without tensioning the tape and cylinder rotation is terminated after a lapse of the 5 minutes. In this manner, other modes in the stop mode can be set quickly, while power consumption is also avoided. When there is no necessity of maintaining channel selection at the VCR tuner, tape loading and power turn-off may be executed after a lapse of the five-minute period to further reduce the power consumption.
