Re: glycol decomposition products

As soon as the conference business all settles down, I have a problem that someone out there might be able to solve. I can theorize with the best of you, but I would dearly like to talk to anyone who has anything, or can direct me to any source, of empirical data on the decomposition products at 371 degrees C (700 degrees F) of the following chemicals:

1. triethylene glycol CAS# 112-27-6
2. monopropylene glycol (proplyene glycol; 1,2-propanediol) CAS# 57-55-6
3. diethylene glycol CAS# 111-46-6
4. dipropylene glycol(s) CAS# 25265-71-8, 106-62-7, 110-98-5, 108-61-2
5. 1,2-butylene glycol (1,2-butanediol) CAS# 584-03-2
6. 1,3-butylene glycol (1,3-butanediol) CAS# 107-88-0
7. glycerin (glycerol; 1,2,3-propanetriol) CAS# 56-81-5
8. white mineral oil, medicinal or food grade CAS# 8042-47-5
9. Dow Polyglycol (Carbowax) E 200 polyethylene glycol
10. Polypropylene glycol MW 200-400

Thanks,

Monona
