Abstract: The present invention relates to methods for purifying one or two cannabinoid compounds using simulated moving bed chromatography, wherein the cannabinoid compound(s) is/are obtained in the extract and/or the raffinate with the total amount of isomeric impurities being below detection level. In particular, the present invention relates to methods for the purification of cannabidiol, trans-(?)-delta-9-tetrahydrocannabinol, cannabidivarin, trans-(?)-delta-9-tetrahydrocannabivarin and cannabigerol which have been obtained by enantiopure synthesis.

Abstract: Phenylene-bis-benzimidazole-tetrasulfonic acid disodium salt which is largely free from impurities can be prepared by reacting o-phenylenediamine with terephthalic acid and chlorosulfonic acid in the presence of strong acids with a reaction time of 10 to 15 hours.

Abstract: A novel apparatus can be used to simulate the chewing process, wherein the wherein the apparatus comprises a thermostattable kneading space comprising an upper portion and lower portion, wherein the lower portion comprises at least two kneading paddles for comminuting and kneading the test material and the upper portion comprising an air space for connecting the volatile components released during the comminution and kneading, wherein said apparatus comprises an inlet in which saliva is introduced into the kneading space and a second inlet in which air is passed into the kneading space, wherein air is passed together with the volatile components of the comminution and kneading process through an outlet of the kneading space to a detector system.
