Quaternary sulfoalkyl or sulfoalkenyl salts of tertiary amine bases are prepared by reacting the tertiary amine bases at elevated temperatures with a hydroxy alkane sulfonic acid or a hydroxyalkene sulphonic acid.

Process for the preparation of sulphoalkyl quaternary salts

Tertiary amines may be quaternized by heating them with a sulfoalkylating agent of this invention to a temperature of from 100.degree. to 250.degree. C. The sulfoalkylating agents which are believed to be hydroxy alkane sulfonic acid sulfoalkyl esters are free from sultone and are prepared by heating a hydroxy alkane sulfonic acid of propane or butane or the corresponding sultone to a temperature in the region of from 80.degree. to 180.degree. C. in the presence of water in an amount of 1 to 4 moles per mole of hydroxy alkane sulfonic acid or alkane sultone.

Process for the preparation of N-sulfoalkyl quaternary salts of nitrogen

Sulphoalkyl and sulphoalkenyl quaternary salts of heterocyclic nitrogen compounds are prepared by reacting heterocyclic compounds containing a tertiary ring nitrogen atom at an elevated temperature with an O-sulphoalkyl or O-sulphoalkenylisourea compound.
