Can anyone give an input on the best method to clean Glycerol from a steel surface? -Inor
What relationship exists between (ethylene or propylene) glycol and glycerin, if any such relationship exists? Do they refer to the same substance?
-Anonymous
- Nope. Glycol is 1,2-ethanediol, glycerin is 1,2,3-propanetriol. One more carbon, one more hydroxyl. --Shaddack 00:26, 4 November 2005 (UTC)
Can someone write about using glycerin as antifreeze in cryogenic process? See

I changed the entry on 'glycerol and biodiesel' as it cited incorrect info (which is widely distributed thanks to a major error in the poorly researched book "From the Fryer to the Fuel Tank".
The original entry stated that esters are broken off from the glycerol during biodiesel production- in fact, a triglyceride (or a diglyceride or monoglyceride) are esters themselves, and in transesterification, the "vegetable oil" ester essentially becomes a different ester when the alcohols are 'swapped', which we call "mono alkyl esters of fatty acids", or biodiesel. The part of the triglyceride molecule that's broken off is the fatty acid chains- which are not esters in themselves.

[edit] frozen temperature
What is glycerol freezing point?
- According to the article the melting point (same as freezing point) is 18 °C. --Ed (Edgar181) 14:21, 11 April 2006 (UTC)
[edit] Extracting glycerol
How would you go about extracting glycerol (+ cellulose also) from an insecticide?
[edit] Glycerol Feed Value
What value does Glycerol contain for livestock feed?
[edit] From transesterfication
If biodiesel ismade using ethanol instead of methanol, glycerol isn't produced?
[edit] In biodigesters
Can glycerol be fed to biodigesters?
- You might want to try asking at Wikipedia:Reference desk/Science. Talk pages aren't for general questions, they're for discussing the article and how to improve it. —Keenan Pepper 22:58, 22 June 2006 (UTC)
[edit] Triglycerol
Should Triglycerol link to glycerol? I noticed the dead link on Ketosis. Note that Triglyceride and Glyceride are separate pages. Rashad9607 17:03, 1 October 2006 (UTC)
[edit] Purification
This section seems to need cleanup. Was a paragraph recently cut that introduced the procedure concerning methnanol? As stands now it lacks context. I would try myself but lack the specific understanding. 68.53.226.105 16:42, 2 December 2006 (UTC)
