Scope

Scope: This document specifies the classification and naming, requirements, test methods, inspection rules, marking, packaging, transportation, storage, and shelf life of industrial 1840 toluene-free alkylene ketone dimers. This document applies to industrial 1840 toluene-free alkylene ketone dimers prepared by reacting fatty acid chlorides with tertiary amines using a toluene-free process as the main raw material. Main technical content: 5.1 Appearance: Light yellow to yellow beads or granules. 5.2 Physical and chemical indicators: The physical and chemical indicators of industrial 1840 toluene-free alkylene ketone dimers shall comply with the requirements of Table 1. Table 1 Physical and chemical indicators Item Standard Alkylene ketone dimer effective component, w/ % ≥88.5 Acidity (KOH), w (mg/g) ≤4.0 Melting point / °C ≥47.0 Iodine value (I2), w (g/100g) ≥45.0 Toluene, w/ % ≤Not detected Note: The detection value is less than 0.0002%, which is considered undetected. 6. Test methods 6.1 General provisions The reagents and water used in this document, unless otherwise specified, refer to analytical-grade reagents and Class III water specified in GB/T 6682. The standard titrant solutions, preparations, and products used in the test, unless otherwise specified, shall be prepared in accordance with GB/T 601 and GB/T 603. The solutions used, unless otherwise specified, refer to aqueous solutions. 6.2 Appearance: Visual inspection. 6.3 Alkylene ketone dimer effective component: According to the method specified in GB/T 27565-2011, section 5.5.2. 6.4 Acidity: According to the method specified in GB/T 27565-2011, section 5.4. 6.5 Melting point: According to the method specified in GB/T 617-2006, section 4.2. 6.6 Iodine value 6.6.1 Summary of the method After the sample is dissolved in solvent, add Weiss reagent and react for a certain period of time, then add potassium iodide solution and water, and titrate the precipitated i
