text: However, it has been found that there is a considerable difference in the order of magnitude of hydrochloride formation and also the further reaction with phosgene depending on whether the hydrogen chloride is brought into contact with the amine which is present in high concentration immediately at the beginning of the reaction and forms amine hydrochloride, which precipitates as a solid, virtually quantitatively, or whether hydrogen chloride formed only in the course of the reaction reacts with the amine which is then only present in a very low concentration to form amine hydrochloride.
