Scope
Main technical content: This document specifies the requirements, test methods, inspection rules, and marking, packaging, transportation, and storage for the by-product sodium sulfite solution. This document is applicable to the synthesis of thionyl chloride and sulfonyl chloride, or the absorption of sulfur dioxide generated during the use of thionyl chloride and sulfonyl chloride as chlorinating agents with liquid alkali to produce by-product sodium sulfite solution. This by-product sodium sulfite solution is mainly used in the production of water-reducing agents, chemical synthesis reducing agents, etc.
