Sodium sulfide nonahydrate (Na 2 S.9H 2 O) can be reacted with α,ω-dibromo and/or α,ω-dichloroalkane for the synthesis of polyalkylene sulfide. It can be used as a reducing agent for the removal of nitrogen oxide from the exhaust gas. Na 2 S.9H 2 O can also be used as an inexpensive sulfur source for the synthesis of heterocyclic thiochromes.
