Abstract

PURPOSE: To manufacture sodium polysulfide as digesting chemicals for the manufacture of pulp without producing sulfur compounds such as sodium thiosulfate by catalytically reacting an aqueous sodium sulfide soln. with a specified oxidation- reduction resin.
CONSTITUTION: When craft pulp is manufactured from lignocellulose material, a soln. contg. sodium polysulfide collected in a process of recovering digesting chemicals for craft pulp is fed into a column packed with an oxidation-reduction resin to produce sodium polysulfide. The resin is prepared by halomethylating a matrix copolymer of an aromatic monovinyl compound and an aromatic polyvinyl compound and bonding quinones such as p-benzoquinone or 1,2-naphthoquinone to the copolymer in the presence of Lewis acid catalyst. The resin reduced by said reaction is regenerated to the oxidation type resin having quinone type structure by feeding an aqueous soln. contg. ferric ions, dichromate ions, etc.
