Keten(e) - what is this?

KETENE - ketenes, are large group of compounds. They are unsaturated ketenes with cumulated double bonding. The simplest of ketenes is just named ketene. Its formula H2C=C=O. Boiling point -56,1 C, so in normal conditions it is a gas. It has sharp characteristic odour and is highly toxic. Because it’s very reactive, it’s a starting material for many interesting reactions. For instance: ketene reacts with water, giving acetic acid, but when all of the water reacts, then we get acetic anhydride. Synthesis of ketene is not a problem: boiled acetone fumes passed through a heated resistance coil gives ketene, or more precisely etenone, ready to use.

CH2=C=O + H2O -> CH3COOH
CH3COOH + CH2=C=O -> (CH3CO)2O
