T/SDHCIA 048-2024 The by-product halide potassium chloride of 2,3,4,5-tetrafluorobenzoyl chloride
Basic Information
Scope
Main technical content: This document specifies the requirements, test methods, inspection rules, and marking, packaging, transportation, and storage requirements for potassium halide (hereinafter referred to as "by-product potassium halide") produced as a by-product of 2,3,4,5-tetrafluorobenzoic chloride. This document is applicable to the process of producing 2,3,4,5-tetrafluorobenzoic chloride using tetrachlorophthalic anhydride, methylamine, potassium fluoride, and other main raw materials. The by-product potassium halide is obtained by replacing the potassium salt wet product in the 2-reaction process, and then centrifuging, washing, and vacuum drying it. The by-product potassium halide from the 2,3,4,5-tetrafluorobenzoic chloride project is mainly used as a raw material for producing potassium fluoride, and it is prohibited from being used in food, feed, aquatic products, and other fields.
