Dendrimer based crude oil demulsifiers have good performance.

Using dendrimer with tree multi-branched structure as a synthesis initiator for demulsifier, obtained demulsifier with many branches, and large molecular weight, excellent interface and penetration ability, has good demulsification break performance for oil emulsion, it can be widely used in oil exploration, petroleum refining and other fields. Dendrimer-based crude oil demulsifiers for crude oil like water-in- oil type emulsion has good demulsification performance. The demulsifier has been used in Shengli Oilfield, Bohai Suizhong 36-1 oilfield, Karamay heavy oil and so on. Weihai CY Dendrimer Technology Co. Ltd.-Professional Manufacturer for low cost dendritic polymers. -The newest 4th class polymers.
