Properties and Synthesis of Octyl Phenol Sulfobetaine Type Surfactant
The type of betain surfactant has wide application foreground in the teriary recovery of oil field.The favorable effect of oil displacement has drew many attention.The experiment is based on the octyl phenol which has fine synthesised by us as raw material.With a series of reactions,we obtained a new sulfobetaine type surfactant which has a new formation that has been verified by IR.Some other tests indicate that this surfactant has low interfacial tension(1.5 × 10-3 mN · m-1),good surface properties (cmc =1.58× 10-3 mol · L-1,γcmc =28.39 mN · m-1)and excellent emulsifying properties,adsorption properties.
