  Organic solvent method of solubility and dissolution:
  EC can be dissolved in various organic solvents, such as fatty acid (ethanol, isopropyl alcohol), other alcohols, ketones, aromatic and so on. Common solvent (volume ratio):
  1)Toluene :Ethanol = 4:1
  2)Ethanol
  3)Acetone :Isopropanol = 65:35
  4)Toluene :Isopropanol = 4:1
  5)Methyl Acetate :Methanol = 85:15
  Alcohols and aromatics in the viscosity of the mixture, with alcohol content higher and lower, when alcohol accounts for 30-35%, the lowest viscosity of the composition. Dissolution method: the EC under the stirring slowly add the container filled with a solvent until complete wetting dissolved.
