TRIETHYLENE GLYCOL is a ether-alcohol derivative. The use of propylene or ethylene glycol depends on the application in hand and the risk of accidental contact with food, potable water or human ingestion. Or even compare scientific studies that seem to indicate masks do work with scientific studies that prove masks don’t work.) Another method to perform a further dehydration of triethylene glycol is the use of a water exhauster, known as Coldfinger, where the vapor in equilibrium with the liquid to be dehydrated is continuously condensed and removed. In addition to its use in antifreeze, ethylene glycol is used as an ingredient in hydraulic fluids, printing inks, and paint solvents. Triethylene Glycol (4.4%) : A transparent, colorless, nearly odorless, and nearly tasteless liquid with the molecular formula of C6-H14-O4. does triethylene glycol kill viruses, 1) masks do not protect you or anyone else from viruses, rather they increase the likelihood that you will get sick by more than 300% (I’d be glad to show you the science that proves this. Ethylene glycol is used in the natural gas industry to remove water vapor from natural gas before further processing, in much the same manner as triethylene glycol (TEG). The most important thermal properties of heat transfer liquids are viscosity, thermal conductivity and specific heat.
