Propylene glycol vs ethanol
WebbThese glycol ethers will undergo many of the same reactions as alcohols because they contain the hydroxyl (-OH) functional group. Some typical examples are: Reaction with carboxylic acids, carboxylic acid chlorides, anhydrides and inorganic acids to produce esters. Reaction with organic halides to produce ethers, such as glymes. WebbAnother important difference is that unlike IAT coolants, OAT products use propylene glycol as the base, so they are less harmful for pets, kids and the environment in case of a spill or boil-over. OAT antifreeze mixes are usually orange, yellow or red but also comes in other colors, such as blue, red and very dark green, depending on the variant and the …
