摘要:
The purpose of the process of the present invention is to remove excess sulfuric acid from a mixture of paraffin-sulfonic acids free or substantially free, from paraffins.In order to remove said sulfuric acid, according to the process of the present invention, the paraffin-sulfonic acid mixture is mixed with one or more halogenated solvent(s), possibly in mixture with sulfuric acid to form a two phase mixture consisting of an organic phase containing paraffin-sulfonic acids dissolved therein and an aqueous phase substantially containing sulfuric acid. The organic phase is then treated with sulfuric acid and the organic phase and aqueous phase are then separated and the organic phase is submitted to evaporation, for the removal of the halogenated solvent(s), and with the concentrated paraffin-sulfonic acids being obtained.
摘要:
Fluoroalkylaryliodonium compounds having the formula (I): ##STR1## wherein AR, A and Rf are as defined above, are disclosed. The fluoroalkylaryliodonium compounds of the present invention are useful as intermediates for producing N-fluoroalkylanilines or derivatives thereof which are important precursors for fluorine-containing disperse azo dyes having an excellent resistance to light.
摘要:
A process for isolating alkanesulfonates having a low alkali metal sulfate content and sulfuric acid from paraffin-sulfoxidation reaction mixtures with the aid of alcohols, the reaction mixture, freed from sulfur dioxide, being mixed in a sequence of five mixer/settler vessels with a C.sub.4 -C.sub.8 -alcohol and the amount of alkali metal hydroxide which is necessary for neutralization. The process is designed so that no alkali metal sulfate, but instead only sulfuric acid, is produced as a byproduct. Fewer alkali metal ions are thereby lost from the system, and the consumption of alkali metal hydroxide for neutralization is accordingly reduced.
