Abstract
Blandinger av C8-C22-alfa-olefinsulfo- nater og alkyletersulfater med formelen RO-(CHjCHjO)i.<S03Na, hvor R er Cg-Cig- alkyl, med ett eller flere alkoksylater av Ci-CiQ-alkoholer, dialkoksylater av visse sykloheksenyldisyrer eller propok- sylerte kvartære ammoniumforbindelser; samt blandinger av fettsyrealkoksylater, fettalkoholalkoksylater og ett eller flere av de nevnte sykloheksenyldisyre- dialkoksylater og Ci-CiQ-alkoholalkoksy- later gir forbedret fjerning av trykk- farge ved trykkfargefJerning fra av- fallspapir ved skumflotasjon.Mixtures of C8-C22 alpha-olefin sulfonates and alkyl ether sulfates of the formula RO- (CH 2 CH 2 O) i. SO 3 Na, wherein R is C 8 -C 18 alkyl, with one or more alkoxylates of C 1 -C 10 alcohols, dialkoxylates of certain cyclohexenyl diacids. or propocylated quaternary ammonium compounds; as well as mixtures of fatty acid alkoxylates, fatty alcohol alkoxylates and one or more of the aforementioned cyclohexenyl diacid dialoxylates and C 1 -C 10 alcohol alkoxylates provide improved ink color removal by ink flotation from foam paper flotation.
