Talk:Diketene

Uses Section[edit]

The uses section contains a large discussion of AKD's, which are related to but not part of the discussion of diketene itself. Any thoughts? JSR (talk) 13:46, 5 January 2017 (UTC)[reply]

An article on AKD's would be welcome. The current picture of the AKD implies a specific stereochemistry which would be nice to verify. It would also be helpful to have an article on alkenyl succinic anhydride. If you know something on these materials and have decent reference or two, the mission is to write articles. --Smokefoot (talk) 15:37, 5 January 2017 (UTC)[reply]

Oops, don't make noise or you will get the mission... JSR (talk) 17:20, 5 January 2017 (UTC)[reply]

Well its not like one must write something elegant. Here's a start:

[[File:AKDstructure.png|thumb|220 px|structure of the AKD derived from stearic acid.]] '''Alkenyl ketene dimers''' (AKDs) are a family of organic compounds that are used in papermaking. In terms of their chemical structure, they are derivatives of ketene dimers, they feature lipophilic alkyl groups extending from a propiolactone ring. A specific example is derived from the ketene of stearic acid. AKDs react with the hydroxyl groups on the celluose via ... ? reaction, conferring lipophilicity. The process is called? sizing. Prior to the development of AKD's, lipophilicity was imparted by incorporating ... into the paper.<ref>Werner J. Auhorn "Paper and Board, 3. Chemical Additives" in Ullmann's Encyclopedia of Industrial Chemistry Wiley-VCH, Weinheim. 2012. {{DOI|10.1002/14356007.o18_o11}}</ref> ==References== <references />

You modify this, post it as a new article, and then let someone who knows more upgrade it. And so it goes. --Smokefoot (talk) 18:24, 5 January 2017 (UTC)[reply]

new synthesis[edit]

User:Grnltrn5 here and here, you added:

An alternative method of producing diketene proceeds through the reaction of acetyl chloride in the presence of triethylamine (in excess) and diethyl ether and occurs at room temperature.^[1]
