Preparation of alkyl ketene dimers |
| abstract |
The embodiments of the process of the present invention relate to the preparation of alkyl ketene dimers (AKD), where the process combines at least one polyamine with a fatty acid chloride in a molar ratio of less than one mole of polyamine to one mole of fatty acid chloride thereby forming an alkyl ketene dimer/amine salt that is subsequently separated into an organic dimer layer and an aqueous salt layer. |
