Beschreibung
Zusammenfassung:	The invention relates to a process for preparing a homologous series of non-ionic-anionic surfactant structures of the p(4)-[beta-2-ethyl-hexyl polyethyleneoxy (n = 3-18) ethyl] alkaline benzoate and/or homogenous alkylammonium benzoates with the general formula: wherein the radical i-C8H17 represents the 2-ethyl-hexyl chain, n is the degree of homogeneous oligomerization of ethylene oxide in the polyoxyethylene chain, with the values: 3, 6, 9, 12, 18, Me+ an alkaline metal cation, MEA + the monoethanolammonium cation, DEA + the diethanolammonium cation, TEA + the triethanolammonium cation, used as homogeneous hybrid nonionic-anionic soaps. Invenţia se referă la un procedeu de obţinere a unei serii omologe de structuri tensioactive neionice-anionice din categoria p(4)-[ β -2-etil-hexil polietilenoxi (n=3-18) etil]benzoaţilor alcalini şi sau de alchilamoniu omogeni cu formula generală: în care radicalul i-C8H17 reprezintă catena 2-etil-hexil, n este gradul de oligomerizare omogen al oxidului de etilenă în catena polioxietilenică, cu valorile:3, 6, 9, 12, 18, Me+ un cation metalic alcalin, MEA+cationiul monoetanolamoniu, DEA+ cationul dietanolamoniu, TEA+ cationul trietanolamoniu, utilizate ca săpunuri hibrid neionice-anionice omogene.
