Patent

CA 1332941

The synthesis of quaternary five membered N-n-alkyl-hetero- cycles, especially of 4-hydroxy-N(1)-n-alkyl-imidazolium, 2,5- substituted N(3)-n-alkyl-thiazolium and substituted N(2) pyra- zolium salts are described. The N-surfactants obtained have a very small critical micelle concentration (CMC) of 10-5 - 10-7 Mol/Liter, and are capable of forming micelles of different sizes and forms depending on the nature of the anions. The N-deter- gents can be used as pharmaceuticals.
