For some of the solvents I deal with at my job, there is a "coefficient of expansion" listed (thermal expansion??) that converts density to 20 degrees C.  I'm trying to find good references, or a way to determine the coefficients myself.   (Otherwise most density readings are when the liquid is at 22-26 degrees C.)

Is there a straightfoward way that I can determine the coefficients for these products, based on some physical properties? (Honestly, an elaborate physics equation will be of no help to me right now. It has to be something practical.)   I'd also like to know if this could be applied to blends.

Any input would be appreciated!

If I understand your question correctly - no.

Can you please send a example. then it will be easy to understand.

Alright here's an example-

I check the density of a sample:     .792 g/mL at 23.6 degrees C

How can I determine the samples coefficient of expansion, so that I can convert the reading to  "at 20 degrees C" ??

...or maybe I just need a better density meter that will take care of this??
