The invention relates to a process for producing alkyl sulfonic acid in a reaction apparatus (41) which contains a liquid phase comprising aqueous nitric acid, wherein dialkyl disulfide is fed into the liquid phase in the reaction apparatus (41) and a crude reaction product is formed in the reaction apparatus (41) by chemical reaction of the dialkyl disulfide with the nitric acid, wherein feeding the dialkyl disulfide comprises at least one of: the liquid dialkyl disulfide is fed into the reaction apparatus (41) through an orifice (28, 29; 33) having a hydraulic diameter of less than 5 mm; the liquid dialkyl disulfide is fed into the reaction apparatus (41) with an inlet velocity of at least 0.6 m/s.
A process for producing alkyl sulfonic acid in a reaction apparatus comprising a liquid phase comprising aqueous nitric acid, the method comprising feeding dialkyl disulfide submerged into the liquid phase in the reaction apparatus and forming a crude reaction product in the reaction apparatus by chemical reaction of the dialkyl disulfide with the nitric acid, wherein feeding the dialkyl disulfide comprises at least one of:
