Talk:Diol

Would be useful to include something about the applications of diol. For example, I recently learned that glycol (ethylene glycol) is used as a refrigerant in heat pump systems. Somebody with better knowledge in this area could maybe write something up. Erik75 13:01, 7 August 2007 (UTC)[reply]

In the section about synthesis: "Using acidic potassium manganate(VII) produces a colour change from clear deep purple to clear green; acidic potassium manganate(VII) turns clear colourless."

It mentions acidified potassium manganate (VII) twice, it should say something different, surely? Tim Goodwyn 23:07, 26 April 2006 (UTC)[reply]

This is fixed now

Nomenclature history

So is "glycol" simply a remnant of an older nomenclature, or is it still approved for some uses? What's the etymology? (The name suggests some connection with sugar or sweetness to me.) 121a0012 (talk) 04:25, 23 October 2010 (UTC)[reply]

I see OED2 claims "[f. GLYC(ERINE) + -OL; the original intention of the name being to designate a substance intermediate in composition between ‘glycerine’ and ‘alcohol’.]" 121a0012 (talk) 04:26, 23 October 2010 (UTC)[reply]

Glycol definition

Here it is said that: "In a vicinal diol, the two hydroxyl groups occupy vicinal positions, that is, they are attached to adjacent atoms. These compounds are called glycols." But according to IUPAC Gold Book 'glycols' are "Dihydric alcohols, also known as diols, in which the two hydroxy groups are on different carbon atoms, usually but not necessarily adjacent." So the adjacency is not a requirement and this statement should be changed? — Preceding unsigned comment added by 193.40.12.10 (talk) 13:36, 25 May 2012 (UTC)[reply]

The article says "An aliphatic diol is also called a glycol." (without any "vicinal" qualification) but also "In a vicinal diol, the two hydroxyl groups occupy vicinal positions, that is, they are attached to adjacent atoms. These compounds are called glycols." (with a "vicinal" qualification). Please clarify.98.149.97.245 (talk) 13:57, 28 April 2022 (UTC)[reply]

differentiating non-cis and non-trans diols from cis and trans

Is there a specific nomenclature for 1,2 diols in which one carbon is not in a ring or double bond, such that one OH is free to rotate so there is no strict CIS or TRANS? Example: C1 and C2 of fructose. Chemistry I am working with requires this conformation. Writing just "1,2-diol" is not specific enough. — Preceding unsigned comment added by 130.238.177.173 (talk) 16:47, 27 January 2014 (UTC)[reply]

Something that I want to improve is clarifying and give more details to the names of the diols. I want to give more attention to cis and trans diols and how to create trans-diol and cis-diol. I want to add some pictures of germinal diols. Finally, I want to add why diols are important and why it is used in chemistry as a section. AFakeDrummer (talk) 06:43, 15 March 2024 (UTC)[reply]
