摘要:
Azole compounds represented by general formula [1a] or [1b]; and herbicide compositions containing effective amounts of the compounds. In said formulas, Q, X, p, R?1 to R6, R12 to R15, and Z1 to Z4¿ are each as defined in the description. The compounds little do chemical damage to cultivated crops and can control various kinds of weeds in low dosage.
摘要:

摘要:
A novel triketone derivative having specific formulas [I-1] and [II-1] where in formula [I-1], R represents a methyl group, X and Y are each a hydrogen atom, a halogen atom or the like, M represents a halogen atom, an alkali metal or the like, R4 represents a halogen atom or an alkyl group having 1 to 6 carbon atoms and m is an integer of 0 to 4 and, in formula [II-1], R represents a methyl group, X is a hydrogen atom, a halogen atom or the like, G represents 3 to 5 ring-constituting atoms which form, together with two carbon atoms of an adjacent benzene ring, a 5 to 7-membered saturated or unsaturated condensed ring, Z1 represents a halogen atom or the like, m is an integer of 0 to 4 and q is 1 or 2; and a herbicide containing the same as an effective component. The herbicide has great utility as an efficient herbicide against weeds inhibiting the growth or development of a plant being cultured, particularly lowland weeds such as E. ulilis (Japanese Millet) and S. juncoides.

摘要:
A powder metallurgy lubricant includes an aromatic carboxylic acid represented by a formula (1), €ƒ€ƒ€ƒ€ƒ€ƒ€ƒ€ƒ€ƒ(Z)n-Ar-COOH€ƒ€ƒ€ƒ€ƒ€ƒ(1) where Ar represents an aryl group and Z represents a substituent directly bonded to the above aryl group and is one of R, OR, OCOR and COOR, R representing one of an alkyl group, alkenyl group and alkynyl group and n being an integer in a range from 1 to 4. Z may be mutually the same or different when n is 2 or larger.
摘要:
Triketone derivatives of general formula (I) or salts thereof; and herbicides for lowland fields characterized by containing at least one of these compounds (wherein Y?1, Y2, Y3¿, n, p, R?1, R2, R3 and R4¿ are each as defined in the description). The triketone derivatives and salts thereof and the herbicides cause little chemical damage to paddy rice plants and can control various lowland weeds, even in a small dose.
摘要:
In a reaction in which a boron trifluoride complex is used as a catalyst, the expensive and harmful boron trifluoride complex is separated from a reaction mixture containing the boron trifluoride complex by separating the boron trifluoride complex present in the reaction mixture by using a saturated hydrocarbon-based solvent.
摘要:
The invention provides processes for the recovery of a catalyst which are to be applied to the reactions wherein boron trifluoride or a complex thereof is used as the catalyst, that is, (I) a process for the recovery of a catalyst which comprises using as the reaction solvent a solvent containing a hydrofluorocarbon compound and/or an oxygenic hydrofluoro- carbon compound and, after the completion of the reaction, separating the reaction solvent from the reaction mixture; and (II) a process for the recovery of a catalyst which comprises extracting boron trifluoride or a complex thereof from the reaction mixture after the completion of the reaction by using a hydrofluorocarbon compound and/or an oxygenic hydrofluoro- carbon compound as the extraction solvent. According to the processes, boron trifluoride or complexes thereof used as catalyst can be easily separated from the reaction mixtures and re-used.
摘要:
A lube base oil which comprises at least one hydrocarbon compound having as the basic skeleton a structure represented by any of the general formulae (I) to (VI) and has a viscosity at -40°C of 40 Pa·s or lower and a viscosity index of 80 or higher, (wherein p is an integer of 1 to 10, provided that in the formulae (I) and (II), p is not 1). It satisfies the coefficient of high-temperature traction, low-temperature flowability, and viscosity index on a high level.
