- In
organic chemistry, a
ketene is an
organic compound of the form RR'C=C=O,
where R and R' are two
arbitrary monovalent chemical groups (or two separate...

Ketene cycloadditions are the
reactions of the pi
system of
ketenes with
unsaturated compounds to
provide four-membered or
larger rings. [2+2], [3+2]...

Alkyl ketene dimers (AKDs) are a
family of
organic compounds based on the 4-membered ring
system of oxetan-2-one,
which is also the
central structural...

Alkylidene ketenes are a
class of
organic compounds that are of the form R2C=C=C=O. They are a
member of the
family of hetero****ulenes (R2C=(C)n=O), and...

Ethenone is the
formal name for
ketene, an
organic compound with
formula C2H2O or H2C=C=O. It is the
simplest member of the
ketene class. It is an important...

presence of
ketene formation when vaporizing. They
reported that just like
Vitamin E acetate, all
three of
these cannabinoid acetates produced ketene gas when...
- an
ethene chain. The
chemical is also
called ketene hydrate because it is the
carbonyl hydrate of
ketene. Its
structure can also be
considered as the...

additive in
transport fuel. In 1928,
ketene production started using acetic acid made by
oxidation of acetaldehyde.

behave as
ketene precursors or synthons.
Ynols can

ethers of
esters (−OR) or
