Abstract:
The invention is a process for reducing the fatty alcohol content of a mixture of fatty alcohol and fatty glycoside product by passing the mixture through a forced circulation evaporation zone to form a mixture of fatty alcohol and fatty glycoside product with a reduced fatty alcohol content and passing the mixture with the reduced fatty alcohol content to a wiped film evaporator to remove additional fatty alcohol.

Abstract:
The invention is a novel bath and process for treating the surface of tin-plated steel that generates only small quantities of sludge in wastewater treatment and imparts, by a low-temperature treatment, excellent corrosion resistance and paint adherence to the surface of tin-plated steel prior to the painting or printing of same. The bath for treating the surface of tin-plated steel is an aqueous solution with pH 1.5 to 3.5 which contains 10 to 500 ppm phosphate, 10 to 500 ppm fluoride as fluorine, and 5 to 500 ppm tin.
