| The non-aqueous solvent is typically a polyhydric alcohol such as propylene glycol. |
| Instead, purchase animal-friendly antifreeze, which contains propylene glycol rather than ethylene glycol, the center says. |
| Another major epoxide, propylene oxide, comes from propene reacting with organic hydroperoxides. |
| Ethylene or propylene gas mixtures were renewed every day after aeration of the jars. |
| Two of the coolants extensively used are ethylene glycol and propylene glycol. |
| He used a catalyst discovered by Karl Ziegler to produce polypropylene from propylene. |
