| 摘要 |
The invention relates to a method for providing a ruthenium catalyst solution which is active during the transvinylation of a surfactant vinyl ester with a surfactant carboxylic acid, comprising an Ru metal concentration of more than 0.5 wt.% based on the total weight of the ruthenium catalyst solution. The invention is characterized in that a) at least one ruthenium (III) halogenide with at least one inorganic or organic base, at least one surfactant vinyl ester, and at least one surfactant carboxylic acid is reacted at a temperature of 70 °C to 170 °C; b) the molar ratio of surfactant vinyl ester to surfactant carboxylic acid is 1 : 1.8 to 1.8 : 1; and c) the ruthenium (III) halogenide is used in a quantity of > 0.5 wt.% of Ru metal based on the total weight of the surfactant vinyl ester and surfactant carboxylic acid. |
