| 摘要 |
The invention concerns a method for producing at least one alkoxylate which consists in contacting at least one alkylene oxide selected from the group consisting of ethylene oxide, propylene oxide, butylene oxide, pentene oxide and decene oxide, with at least one initiator, in the presence of at least one double metal cyanide type compound. The invention is characterized in that said reaction is carried out at a temperature ranging between 130 ¦C and 155 ¦C. The invention also concerns the alkoxylates, in particular ethoxylates, thus produced, as well as their use as emulsifiers, foam adjusting and wetting agents for hard surfaces. |
