Surface-active compounds, a process for their preparation and their use |
摘要 |
The new compounds consist essentially of ethylene oxide/propylene oxide block polymer units and oxyalkyleneated alkylphenol/aldehyde resin units, which are linked by methylene groups. They are prepared by reacting a block polymer of ethylene oxide and propylene oxide and an oxyalkyleneated alkylphenol/aldehyde resin with formaldehyde. The new compounds constitute especially advantageous breaking agents for petroleum.
