Abstract (en)
[origin: WO9530473A1] A method of separating a solute from one or more other solutes in a solution comprises insolubilising the solute to be separated from the solution, and passing the insolubilised solute and the remaining solution in contact with a membrane. The insoluble particles cannot pass through the membrane filter but the solute(s) remaining in solution pass through the membrane filter and are thus separated from the insoluble particles. This method is particularly suitable in the manufacture of N-acyl taurate derivatives, and especially in the manufacture of sodium N-cocoyl, N-methyl taurate.
