Abstract
A method is described for producing lactamates by reacting alcoholates with lactams, wherein a reaction mixture comprising at least one alcoholate and at least one lactam is subjected to thin film evaporation.
Claims22
A process for preparing a lactamates, comprising:
- forming a reaction mixture comprising at least one alkoxide and at least one lactam;
- performing a reactive distillation to the reaction mixture, thereby reacting the at least one alkoxide with the at least one lactam.
(canceled)
The process as claimed in claim 16, further comprising:
- homogenizing the reaction mixture, prior to performing the reactive distillation, at a temperature which is selected such that there is essentially no reaction of the lactam with the alkoxide, thereby, forming a homogenized reactant mixture;
- feeding said homogenized reactant mixture into the thin-film evaporator;
- and
- obtaining the lactamate at the bottom of the thin-film evaporator.
