Scope

Scope: This document specifies the classification, requirements, test methods, inspection rules, marking and labeling, packaging, transportation, storage, and safety of industrial-grade mixed polyamines, which are by-products of adiponamide. This document applies to industrial-grade mixed polyamines obtained by refining the reaction solution during the synthesis of adiponamide from adiponitrile and hydrogen. Note: Industrial-grade mixed polyamines, which are by-products of adiponamide, are mainly used as raw materials for epoxy resin curing agents and other products. Main technical contents: Project requirements: Type I: Colorless liquid Type II: Yellow liquid Total amine value (mg KOH/g) ≥900 ≥600 Main content, a, w/% ≥95 ≥85 Water content, w/% ≤5 ≤3 Sodium hydroxide, w/% ≤0.05 ≤3 a: The main content of Type I products includes the sum of 1,2-cyclohexane diamine and 1,6-cyclohexane diamine; the main content of Type II products includes the sum of 1,6-cyclohexane diamine, N-ethyl adiponamide, and bis(hexamethylene) triamine.
