Alkyl phenoxy polyethoxy ethanols

Alkyl phenoxy polyethoxy ethanols (alcohol ethoxylates). 

A Zr0(N03)2 2H20 solution (2.4 M) was denitrated by solvent extraction (1/3 v/v) with an alkyl tertiary amine diluted in an organic solvent (1/10 v/v) (Solvesso 100 ). The final Zr + content was 2.3 M, the [NO MZr ] molar ratio was 0.95 and the viscosity (ri) was about 40 mPa-s. The extractant was regenerated by a continuous process. The solution was diluted to 1.0 M, then an organic additive, e.g. methyl cellulose (1%) and a surfactant e.g. iso-octyl-phenoxy-polyethoxy-ethanol, were added.
