摘要： Disclosed is a method for producing a fluoroalkanesulfonic acid including (1) the step of reacting concentrated sulfuric acid and/or fuming sulfuric acid with a fluoroalkanesulfonate to cause an acid decomposition, thereby obtaining a reaction mixture containing the fluoroalkanesulfonic acid and a sulfur component; and (2) the step of adding an oxidizing agent to the reaction mixture obtained by the above step and then conducting a distillation, thereby obtaining the fluoroalkanesulfonic acid from the reaction mixture. It is possible by this method to efficiently reduce the sulfur component, thereby industrially advantageously obtaining fluoroalkanesulfonic acid of high purity.

摘要： A production process of a trialkylphosphine according to the present invention includes: a first step of forming a trialkylphosphine by reaction of an organic metal compound and an organic phosphorous compound in an ether solvent having a difference in boiling point with the trialkylphosphine formed such that the difference in boiling point is in a range of 0° C. to 20° C.; a second step of obtaining a silver complex by absorption of a gas phase of the first step into an aqueous solution of AgI and KI; a third step of heating the silver complex obtained in the second step, in a metallic reaction vessel, at a temperature of 170° C. to 350° C. in a reduced pressure atmosphere of 1.333×10−7 MPa to 6.133×10−2 MPa; and a fourth step of cooling a gas product of the third step at a very low temperature range of −196° C. to −50° C. to trap the trialkylphosphine.
