摘要：
The invention relates to a method for producing onium alkyl sulfates by reacting an onium halogenide with a symmetrically substituted dialkyl sulfate, the alkyl group thereof containing between 1 and 14 C atoms, with an unsymmetrically substituted dialkyl sulfate, one alkyl group containing between 4 and 20 C atoms, and the second alkyl group being methyl or ethyl, with an alkyl-trialkylsilyl sulfate, with an alkylacyl sulfate, or with an alkylsulfonyl sulfate, the reaction with the dialkyl sulphate taking place at room temperature.
