Abstract: A process prepares a compound containing at least one cyclic monothiocarbonate group, wherein a salt of an acidic compound with at least one acidic hydrogen atom is reacted with a compound of formula (I),
wherein one of the groups R1 to R4 is a group of formula (II), -A-X, with A representing an organic group with at least one carbon atom and X representing a halide, and the remaining groups R1 to R4 independently from each other represent hydrogen or an organic group with 1 to 50 carbon atoms.-

Abstract: The present invention relates to a process for purifying ethylenediamine (EDA) by distillation, wherein the process comprises the steps a) and b). In step a), a mixture (G1) comprising water, EDA and N-methylethylenediamine (N-MeEDA) is fed into a distillation apparatus (D1), and the major part of the water comprised in the mixture (G1) is separated off overhead at a pressure of greater than 4.8 bara. From the bottom of (D1), the water-enriched mixture (G2) is fed into a distillation apparatus (D2) in step b). At the top of (D2), the major part of the N-MeEDA is distilled off. The stream (S3) obtained from the bottom of (D2) comprises EDA, with the components water and N-MeEDA comprised in the mixture (G1) having been largely or completely removed. Further distillation steps can optionally be carried out in order to obtain pure EDA, for example when diethylenetriamine (DETA) is additionally comprised in the mixture (G1). If ammonia is additionally comprised in the mixture (G1), an ammonia removal is preferably additionally carried out before carrying out the step a) in the process of the invention.
