T/CPCIF 0338-2024 Three-Fluorinated Dichloropyridine By-Product Industrial Potassium Chloride
Basic Information
Scope
Scope: This document specifies the technical requirements, test methods, inspection rules, marking, packaging, transportation, and storage for industrial potassium chloride produced as a by-product of trifluorodichloropyridine. This document applies to potassium chloride wastewater generated during the production of trifluorodichloropyridine. The potassium chloride is obtained through cooling and crystallization, centrifugal separation, and then recovered through high-temperature cracking, impurity removal, crystallization, and drying processes. Main technical content: Project indicators: - First-grade qualified product: Oxide of potassium (K2O) content/% ≥ 62.0 - 58.0 - Water content (H2O) content/% ≤ 2.0 - 2.0 - Calcium and magnesium content (Ca + Mg) content/% ≤ 0.5 - 1.2 - Fluoride (calculated as F) content/mg/kg ≤ 2.0 - 5.0 - Water-insoluble matter content/% ≤ 0.1 - 0.5 - Total organic carbon (TOC) content/mg/kg ≤ 100 - 100
