Image problem[edit]

The carbon atom shown here only has three bonds. It needs to have a hydrogen on it (for acetals), or another R group (for ketals).

  • Missing H on C now fixed. Delta G 15:36, 11 Jul 2004 (UTC)

Glycoside[edit]

Why is Glycoside redirected to this article? Nothing currently in the article text mentions glycoside. Could someone knowledgeable make the connection explicit? Thank you. -- Jeff Q 19:40, 10 Jul 2004 (UTC)

  • I agree the redirect was not obvious. I replaced it with a stub that links to glycosidic bond where things get explained in more depth. FYI, the tenuous link was that a glycoside contains an acetal. -- Delta G 14:39, 11 Jul 2004 (UTC)

Acetal[edit]

how do you properly pronounce????

Acetal formation image[edit]

An IP left this comment in the article and I'm moving it here:

"This picture is incorrect: it starts with a ketone, therefore this is a ketal, not an acetal."

In modern terminology (now explained in the article), "ketal" is a more specific category within "acetal" rather than being two separate types that differ by ketone-vs-aldehyde. DMacks (talk) 12:07, 6 February 2011 (UTC)

Thermal Expansion[edit]

  • I added a note about thermal expansion. acetal is terrible for this. polyprop would be a better alternative. —Preceding unsigned comment added by 81.151.155.157 (talk) 09:01, 7 June 2009 (UTC)

Terminology question[edit]

  • AREN'T ACETLAS A SUBSET OF KETALS NOT THE OTHER WAY ROUND? —Preceding unsigned comment added by 143.167.229.218 (talk) 07:39, 1 February 2011 (UTC)
Nope. I just added a link to the Gold Book ref for "ketals", which states "a subclass of acetals." DMacks (talk) 12:13, 6 February 2011 (UTC)

Merge Acetalisation into Acetal?[edit]

One is a reaction, the other is the product of the reaction. There is not much content on the product, and actually a large part of the product article is about the reaction that makes it. Much of what's important about the product seems to be (or at least is highly related to) the specific chemistry of it, i.e., the reaction that forms it. Perhaps some day someone will write tons of material about one or the other enough to merit separate articles, but for now seems like it's duplicated content and/or closely related important content spread over multiple places.

Support per the nom. Wizard191 (talk) 18:42, 7 February 2011 (UTC)
Support seems to make sense to discuss the functional group in the same article as the synthesis thereof.--Smokefoot (talk) 21:15, 14 October 2012 (UTC)


Acetal/ethanal...[edit]

Acetal is also the name (shouldn't WP reflect this?) of a particular acetal, 1,1-diethoxyethane (named "acetal" after the three ethyl groups?). Confusingly, "acetal" looks like a synonym for "ethanal", which I see it is not. --lifeform (talk) 04:51, 2 June 2014 (UTC)

We didn't have an article about that specific chemical on the English wikipedia (but did on other languages'). I created a stub article about it and added a hatnote link at the top of the page. DMacks (talk) 06:32, 2 June 2014 (UTC)
