Isopropyl alcohol can also be used as the solvent of oil and gel as well as for the manufacture of fishmeal feed concentrate. Low-quality isopropanol can also be used in automotive fuels. As the raw material of production of acetone, the usage amount of isopropanol is reducing. There are se...
It is miscible with water, methanol and acetone. It is soluble in benzene, ether, slightly soluble in carbon tetrachloride, n-heptane. It is a kind of strong alkaline, combining with protons, can be used for condensation reaction. Production Triethanolamine is produced from the reaction of ...
In addition, an amount of dry erase marker solvent or alcohol makes the ink dry quickly. So, the ink just bonds with the surface without any occurrence of absorption. Moreover, you’ll find it easy to wipe the marks as the ink is in a specific place. ...
