| titleOfInvention | Continuous production process of surfactant mixtures |
| abstract | The invention relates to a process for preparing a surfactant (pre) mixture A, which comprises the following process steps: I) melting a compound of the following formula (i) in the The radical R is a straight-chain or branched, saturated or mono- or polyunsaturated alkyl or alkenyl radical having 8 to 24 carbon atoms, - The radicals R 1 , R 2 and R 3 are independently a hydrogen atom, a hydroxyl group or a C 1 -C 4 alkyl group, and - the index n stands for one of the numbers 2, 3 or 4, wherein at least one of R 1 , R 2 and R 3 is a hydroxyl group and wherein not two hydroxyl groups are simultaneously attached to a carbon atom, II) adding a 2- to 8-fold excess of water at a temperature> 65 ° C and mixing the water with the reaction mixture prepared in step I), III) Adding at least one of (i) different surfactant (ii) selected from - Alkyl sulfate and / or Alkylpolyglycolethersulfatsalzen and / or - amphoteric / zwitterionic surfactants of the following formula in which the radical R is a straight-chain or branched, saturated or mono- or polyunsaturated alkyl or alkenyl radical having 8 to 24 carbon atoms, and Mixing the surfactant (s) (ii) with the reaction mixture prepared in process step II), IV) adding water (ad 100) at a temperature of 20 ° C +/- 5 ° C, with the proviso that the weight ratio of the compound (s) of formula (i) to the surfactant (s) (ii) is 1: 6 to 2: 1. |
