Abstract:
Provided is a method for producing a polyunsaturated fatty acid while preventing deterioration of a silver salt solution. A method for producing a composition comprising a polyunsaturated fatty acid, comprising: supplying an aqueous solution comprising a silver salt into a reaction vessel to contact the aqueous solution with a raw material solution comprising an alkyl ester of the polyunsaturated fatty acid; and collecting the aqueous solution comprising the silver salt which has been contacted with the raw material solution from the reaction vessel, wherein the supply of the aqueous solution comprising the silver salt into the reaction vessel and the collection of the aqueous solution comprising the silver salt from the reaction vessel are carried out concurrently with each other.

Claim (Index 28):
The apparatus according to  claim 27 ,\n further comprising a second reaction vessel, wherein the second reaction vessel comprises an organic solvent inlet port through which an organic solvent is to be supplied into the reaction vessel, an aqueous solution inlet port through which the aqueous solution collected through the aqueous solution collection port in the first reaction vessel is to be supplied into the second reaction vessel, an aqueous solution collection port through which the aqueous solution that has been contacted with the organic solvent is to be collected, and an organic solvent collection port through which the organic solvent that has been contacted with the aqueous solution is to be collected, the organic solvent inlet port is arranged at the lower part of the second reaction vessel and above the aqueous solution collection port, the aqueous solution inlet port is arranged at the upper part of the second reaction vessel, above the organic solvent inlet port and below the organic solvent collection port, and the aqueous solution supplied through the aqueous solution inlet port flows downward in the second reaction vessel and the organic solvent supplied through the organic solvent inlet port flows upward in the second reaction vessel while flowing countercurrently to each other in the second reaction vessel so that the aqueous solution and the organic solvent are contacted with each other, and the contacted aqueous solution is collected outside the second reaction vessel through the aqueous solution collection port.
