On the demulsification of SOFTANOL90 (polyoxyethylene ether of secondary alcohols)
Thread Content
I have come across an surfactant named SOFTANOL90 produced by Nippon Catalyst, which is an emulsifier with excellent performance. I work in wastewater treatment. I would like to ask the experts: are there any good demulsifiers or demulsification methods that can separate oil from water containing such emulsifiers?
This requires combining theory with practice: look up information on CNKI and then determine it through experiments. . . Miller’s profile picture is nice. . . :curse:
I’ve already done all of what you mentioned; I can’t even find any articles on secondary alcohol polyoxyethylene ethers on CNKI. There are quite a few articles on polyoxyethylene ethers, but they all deal with their synthesis, not with demulsification. In fact, inorganic demulsifiers have no effect at all.
Then try organic demulsifiers, such as quaternary ammonium compounds. Shall I give it a try for you?
