Title:
REMOVAL OF SULFURIC ACID FROM REACTION MIXTURE OBTAINED BY SULFOXIDE OF PARAFFIN
Document Type and Number:
Japanese Patent JPS58172363
Kind Code:
A
Abstract:
A process for separating sulphuric acid from the product mixture resulting from the sulphoxidation of paraffins, which comprises adding an organic amine sulphate to the product mixture and separating off the resulting phase comprising water and sulphuric acid, adding alkali metal hydroxide to the phase containing the remaining alkanesulphonic acid and alkanesulphonic acid amine salt in an amount sufficient to convert the alkanesulphonic acid and the alkanesulphonic acid amine salt into the alkali metal alkanesulphonate with liberation of the organic amine, separating off the paraffin together with the free organic amine from this mixture by steam distillation, separating off the free organic amine from the paraffin by extraction with sulphuric acid and using the organic amine sulphate obtained again at the beginning of entire process for separating sulphuric acid.
