WebPropylene glycol and di-propylene glycol are chosen as the two final co-solvents. Both Michigan DME blend I and II achieved viscosity equivalent to No. 2 diesel fuel (i.e., 1.9cSt at 40 °C) at around 40–43 wt% DME content. Both Michigan DME blends can maintain the key original merits of DME. Web1. Take two test tubes and set them in a rack. Add 2 ml of water to the first test tube and 2 ml of ethanol to the second test tube. Add 2 ml of your unknown to each test tube, shake well, and observe whether the two liquids mix completely, partially or not at all. 2. If the two liquids mix completely, it will appear as if only one liquid is ...
