Hello all: “ETHYLENE GLYCOL MONOMETHYL ETHER” has a MSDS sheet at
http://www.chem.utah.edu/MSDS/e.html but what is the difference
between this and “ETHYLENE GLYCOL MONOBOTYL ETHER”?
If you know, let me know, please

Difference between “ETHYLENE GLYCOL MONOMETHYL ETHER” and
"ETHYLENE GLYCOL MONOBOTYL ETHER"

I think you mean MONOBUTYL and not MONOBOTYL.

An ether has two chains of carbon atoms attached by a oxygen. With
the monomethyl, one of these chains would have one carbon atom
attached to the glycol. With the monobutyl, one of the chains would
have four carbon atoms attached to the glycol. The toxicity
problems would be about the same or slightly worse. The boiling
point (and melting point) would be somewhat higher.

G’day Michael; I think that perhaps you mean monobUtyl ether? The
first one contains a methyl group and the second a butyl group.
However, how this difference might affect the physical properties
I wouldn’t know; my reference books are now pretty old (like their
owner) and dont include these substances. Solvent properties would
be similar I expect. What would you use EGME for anyway?
Cheers,

Hello John: It is in the ultrasonic cleaning solution that I have
been using for about 4 years now. I wanted to find out more about
possible side effects caused by heating it in the ultrasonic before
I suggested its use to others. The Caution: on the bottle says
"Contains 2-Butoxyethanol. Avoid prolonged usage or heating open
solutions without adequate ventilation". Would you happen to know
what the side effects would be to clue someone that they did not
have adequate ventilation?

G’day Michael; You have caught me out this time; I know nothing
about 2-butoxyethanol.

I can only suggest that the vapour might not do one’s lungs much
good, since they tell users to work in a well ventilated space.
Sorry, I just can’t help. Cheers,
