标 题:Producing sodium borohydride with high energy efficiency and recycles of by-product materials
发明人：HONG ZONGXUAN
权利人:HONG ZONGXUAN
摘要:A method for synthesizing sodium borohydride compound with reduced energy usage and recycles of by-product materials involved in the application and synthesis processes of sodium borohydride is disclosed. The method utilizes a sodium-sulfur electrochemical cell flow system for synthesizing sodium metal and incorporates the sodium metal produced in the commercial sodium borohydride synthesis processes known in prior arts, for example, the “Schlesinger processâ€?. Furthermore, the by-product materials involved in the application and synthesis of sodium borohydride are recycled through a series of processes.

摘要:3-Halosulfonylthiophene-carboxylic acid compounds are manufactured by reacting 3-ketothiophane-carboxylic acid compounds with sulfonic acid compounds, reacting the end product from the 1st reaction stage with alkali metal polysulfides, reacting the end product from the 2nd stage with a dehydrogenating agent and finally reacting the end product from the 3rd stage with halogen and water. The products are starting compounds for the manufacture of drugs, dyes and crop protection agents and have an anti-inflammatory, analgesic and anti-rheumatic action. In particular, the end products I are starting materials for the manufacture of sweeteners which are non-toxic and free from an after-taste, flavor-improving agents, diabetic aids and feedstuffs, and provide the means of a simple and economical synthesis of thiophene-saccharins.
