Abstract
PURPOSE: To carry out the title treatment in a very short time by decomposing PSCl3 or a PSCl3-contg. mixt. with an aq. soln. of a caustic alkali of a specific concn. in the presence of a surfactant other than cationic one.
CONSTITUTION: PSCl3 or a PSCl3-contg. mixt. is decomposed with a 5W30 wt% aq. soln. of a caustic alkali in the presence of 0.05W0.5 g/l of an anionic, nonionic or amphoteric surfactant to be made harmless without forming H2S in a short time. The decomposed product is optionally air oxidized at 30W90°C in the presence of 50W300 ppm anthraquinone disulfonate as catalyst, whereby the resulting product is more perfectly made harmless and does not form H2S even in contact with acidic substances.
