摘要： PROBLEM TO BE SOLVED: To obtain an antimicrobial agent having a wide antimicrobial spectrum an sufficient antimicrobial effects by contact in a short time by including a specific unsaturated phosphonim salt as an active ingredient therein. SOLUTION: This antimicrobial agent is prepared by including an unsaturated phosphonium salt represented by formula I (R to R are each a 1-22C alkyl, preferably a 1-18C alkyl; B is a group represented by formula II or III; X is H a 1-4C alkyl or phenyl; Y is H or methyl; A is an organic acid anion or an inorganic acid anion) as an active ingredient therein. The unsaturated phosphonium salt represented by formula I is obtained by reacting, e.g. a trioraganophosphine with an unsaturated carboxylic acid compound represented by formula IV, providing a phosphonium salt having a betaine structure, then reacting the resultant phosphonium salt with an organic acid or an inorganic acid represented by H A , affording a phosphonium salt having carboxyl group and further reacting the prepared phosphnium salt with an acrylate compound represented by formula V (D is represented by formula VI or VII).

摘要： PROBLEM TO BE SOLVED: To enable valuable metals contained in waste lithium batteries to be selectively separated, purified, and recovered by extracting the metals with a phosphorus compd. such as a bis(1,1,3,3-tetramethylbutyl)phosphinic acid deriv. SOLUTION: This extractant for valuable metals comprises a phosphorus compd. represented by the formula (wherein X and X are each O or S) [e.g. bis(1,1,3,3-tetramethylbutyl)phosphinic acid deriv.]. Valuable metals such as Co and Ni are recovered as follows: a crushing product obtd. by baking and crushing waste lithium batteries is treated with an aq. alkali soln. (e.g. an aq. ammonia soln.); thus obtd. recovered product is dissolved in an aq. mineral acid (e.g. sulfuric acid) soln. and filtered to be separated into a soln. and a residue; then the soln. under the control of pH is brought into contact with a soln. of the extractant in a solvent (e.g. toluene) to conduct extraction and separation; and the extractant soln. is brought into contact with an aq. mineral acid soln. to cause backward extraction and separation to recover high-purity valuable metals.

摘要： PROBLEM TO BE SOLVED: To obtain a high purity monoalkylphosphine useful as a raw material for compound semiconductors and provide a method for producting the high purity monoalkylphosphine in high yield. SOLUTION: This high-purity monoalkylphosphine is represented by the formula RPH2 (R is a 1-8C alkyl group). The compound has >=58wt.% purity and substantially does not contain sulfur and silica. The method for producing the high-purity monoalkylphosphine comprises using anhydrous hydrofluoric acid as a reaction catalyst for phosphine and alkene, carrying out the above reaction in the presence of an organic solvent (e.g. n-octane or isooctane) having a boiling point higher than that of the resultant monoalkylphosphine, bringing the produced reaction solution into contact with an alkali solution, removing the remaining catalyst into water phase as a fluoride, successively bringing the resultant reaction solution into contact with an alkali-based hydride to remove impurities and distilling the treated reaction solution.

摘要： PURPOSE:To establish a regeneration subsystem of an aged negative solution by selectively extracting iron ions contained in the aged negative solution with a trialkylphosphineoxide extraction agent for separation, then reversely extracting the extraction agent. CONSTITUTION:As an extraction agent for extracting iron ions in an aged negative solution, a solution containing trialkylphosphineoxide is used. The amount of the extraction agent is 1.5 times or more mole of R3PO based on the amount of iron ions dissolved. The volume ratio of the aged negative solution to the extraction agent is around 1:1. The trialkylphosphineoxide solution containing iron ions extracted is mixed with a desired aqueous solution in an extraction condition similar to the above extraction process to reversely extract the iron ions in the aqueous solution. The regenerated solution containing trialkylphosphineoxide is circulated as the extraction agent of the aged negative solution.
