Ketene - an overview | ScienceDirect Topics
The simplest ketene (CH 2 C O, ethenone) also is named just ketene. Ketenes are reactive compounds that dimerize to diketenes. Some ketenes such as ethenone dimerize, forming a lactone (oxetan-2-one). Methyl ketene generates two dimers, one with a lactone structure and the other having a cyclopbutandione structure.
Ketene - History, Preparation, Properties, Uses and Synthesis
Ketene is a highly reactive compound that reacts with compounds that have an easily substituted hydrogen atom to produce acetic acid derivatives. The reaction of ketene with acetic acid to form acetic anhydride is the only significant industrial use of ketene. [Image will be Uploaded Soon] History of Ketene Chemistry
