Abstract

Inventia se refera la noi agenti activi de suprafata cu structura corespunzatoare formulei generala I: (vezi formula) în care R - reprezinta izo-octil, nonil, dodecil sau cumil, R1 este un atom de hidrogen sau gruparea R2 care reprezinta un rest: (vezi formula) iar (x+y+z) - reprezinta gradul de policondensare a componentei hidrofobe cu etilenoxid sau propilenoxid si este cuprins între 3...50 moli pentru un rest fenolic. Agentii activi de suprafata cu formula generala I, se obtine prin condensarea Mannich a alchil - sau aralchilfenolilor cu formalina, sau paraformaldehida si o amina secundara sau dietanolamina, urmata de policondensarea cu alchilenoxizi a bazei Mannich purificate prin decantare si apalare sau prin distilare azeotropa.The invention relates to novel surface active agents having the structure corresponding to the general formula (I): wherein R represents isooctyl, nonyl, dodecyl or cumyl, R 1 is a hydrogen atom or the group R 2 which represents a residue: see formula) and (x + y + z) - represents the degree of polycondensation of the hydrophobic component with ethylene oxide or propylene oxide and is between 3 ... 50 moles for a phenolic residue. Surface active agents of the general formula I are obtained by condensing Mannich of the alkyl- or aralkylphenols with formalin or paraformaldehyde and a secondary amine or diethanolamine followed by polycondensation with Mannich-based alkylene oxides by decantation and apalation or by azeotropic distillation.
