Density of Aqueous Ethylene Glycol @ -30C 1

[MINO9]

I have been searching the web and have not been able to find the density of Aqueous Ethylene Glycol (50/50 with H20) @ -30C.

I want to use this to see the volume change between 20C and -30C. (I have density at 20C)

If you have other suggestions on the calculation this would be helpful.

My calc's show a gravity of 1.048 of 50/50 (mass) at -30 Deg C. Check with Dow for tech info or contact your chem supplier.

Promax tells me 1.09493 at -30 C - interesting.

My bookmarks appear to be out off date but a search for Wintrex brought this link. They ahve oyther grades and a nice store of info.

I got a closer value to that of maddocks @1.0899. Did some intrapolation for the constants from Dow's data. Get the EG Product Guidefrom Dow.
