Product Description Chemical name:Sodium AcetateMolecular formula:C2H3NaO2; C2H3NaO2·3H2OMolecular weight:Anhydride:82.03; Trihydrate:136.08CAS NO:Anhydride:6131-90-4; Trihydrate:127-09-4Character:It is white crystalline powder or block, odorless, slight bitter. Relative density is 1.582. Melting point is 324oC. It has strong moisture absorption and highly dissolves in water.Usage:It is used as buffering agent, seasoning reagent, etc.Anhydrous sodium acetate is used in heat packs initiate and sustain the exothermic reaction that produces heat. When anhydrous sodium acetate is mixed with water, it forms a supersaturated solution. This solution can be triggered to crystallize, releasing heat in the process. The crystallization is often initiated by a small metal disc inside the heat pack that, when flexed, creates nucleation sites for the crystals to form. This reaction is what provides the warmth in a heat packPackaging:It is packed with polythene bag as inner layer and polywoven bag as the outer layer. The net weight of each bag is 25kg.Storage and Transport:It should be stored in a dry, clean and ventilative warehouse, and kept away from water and moisture during transport, unloaded with care as to avoid damage to bags. Be cautious to keep away from moisture and hot.Specification2011-19Content (As Dry Basis), w/% ≥98.5Test of Free Acid and Free Alkalipassed testingHeavy Metals(As Pb),mg/kg ≤10As ,mg/kg ≤3Loss on Drying, w/%no water ≤2.0crystal product36.0-42.0
