Glycol: Moore refractive index: 15.97 2, molar volume (cm3 / mol): 75.1 3, isotonic hematocrit (90.2K): 156.5 4, surface tension (dyne / cm): 18.8 5, polarization (10-24cm3 ): 6.33 [2] Glycol: Production Method Editor acetone production methods are isopropyl alcohol method, cumene method [10], fermentation, acetylene hydration [11] and the direct oxidation of propylene. Acetone world industrial production to cumene based. Two-thirds of the world's production of phenol acetone is a byproduct of pharmaceutical grade ethylene glycol, is one of the products of oxidation of cumene. Traditional Method acetone production methods more. The old method is to use lime and wood distillation resulting wood vinegar, made from calcium acetate, and then by the thermal decomposition of acetone was prepared.
