Document Type and Number:
WIPO Patent Application WO/2013/172190
Kind Code:
A1
Abstract:
A method for producing a "salt or complex composed of an imidic acid and an organic base (B)" represented by formula [1], which comprises: a step wherein a sulfuryl halide (SO2X2X3, wherein X2 and X3 represent the same or different halogens) and ammonia are reacted with each other in the presence of the organic base (B) so as to obtain a reaction mixture (a reaction step); a step wherein water is added to the reaction mixture so that the reaction mixture is separated into an organic mixture that contains the "salt or complex composed of an imidic acid and an organic base (B)" and an aqueous layer that contains the "salt or complex composed of an imidic acid and an organic base (B)" (a cleaning step); and a step wherein the aqueous layer that is separated in the cleaning step is brought into contact with an organic base (A) so that the "salt or complex composed of an imidic acid and an organic base (B)" is extracted into the organic base (A) (a recovery step).
