    摘要： A process for the separation of sulphonated paraffins from their sulphonation medium, which comprises neutralization of the sulphuric acid present and separation into two phases, the lower phase containing the sulphate. The neutralization is carried out in such a way that only a part of the sulphuric acid is neutralized. A hydrocarbon is added, which dissolves the sulphonated and non-sulphonated paraffins and forms with water, an azeotropic mixture which is distilled in order to remove all or a part of the water present. The process allows the separation of sulphonates which are purer than in the past and which are poor in sulphates, while the sulphate layer contains only very little sulphonic acid.
