Abstract

PURPOSE: To obtain a Na2CS3 soln. of high concn. and high purity useful as a metal capturing agent, industrial chemicals, etc. by catalytically reacting a Na2S soln. of high purity with equimolar CS2 at a temp. below the b.p. of CS2.
CONSTITUTION: A 32W38% Na2S soln. and 1W0.9, pref. 1 mol of CS2 to 1 mol of Na2S are catalytically reacted at 25W40°C and stirred until the separation of vaporization condensation phenomenon of CS2 disappears, obtaining a Na2CS3 soln. of high purity and high concn. The Na2CS3 soln. thus obtd. exhibits the remarkable effect of capturing metals such as Hg, Cu and Cd, and it is useful as a treating agent for waste water contg. heavy metals.
