| titleOfInvention | PREPARATION OF RENTERS OF ALQUILCETENOS. |
| abstract | A process for the preparation of alkyl ketene dimers comprising in sequence the steps of: (a) loading a polyamine into a reactor and then heating the polyamine to a temperature ranging from 50 to 70 ° C, (b) loading a fatty acid chloride in the reactor containing the polyamine over a period of time ranging from 30 to 90 minutes, thereby forming a reaction mixture comprising an amine salt / alkyl kethene dimer, (c) adding an amount of water to the reaction mixture whereby an organic layer of alkyl kethene dimer and an aqueous layer of salt are formed, and (d) separating the organic layer of alkyl kethene dimer and the aqueous layer of salt, a process in which the polyamine used It is present in amounts ranging from 0.5 to less than 1.0 equivalent per equivalent mole of fatty acid chloride. |
