Scope: This standard specifies the density method and titration method for the determination of glycerin content. The density method is suitable for high-content refined glycerin products and aqueous solutions of pure glycerin; the titration method is suitable for various glycerin products, but not for glycerin products containing organic compounds with more than two hydroxyl groups on adjacent carbon atoms, such as sugars, Because it can also be oxidized to produce formic acid, which interferes with the determination. Note: The non-glycerol organic matter in glycerol will make the density method result higher, but the titration method will not be affected.
