Process for the preparation of fatty alcohol polyglycol ethers with reduced residual EO or PO content |
| abstract |
The alkoxylation of preferably longer-chain alcohols and comparable partial reaction products of polyhydric alcohols in the presence of basic alkali metal compounds as catalysts is described, the reaction being carried out with increased minimum concentrations of the basic catalyst to reduce the residual content of free ethylene oxide to values below 1 ppm or of free propylene oxide to values below 5 ppm in the reaction product initially obtained. The process according to the invention at the same time enables the improvement of the cold characteristics of selected reaction products having surfactant or emulsifying action. |
