NOVEL COUPLED HYDROCARBYL-SUBSTITUTED PHENOL MATERIALS AS OILFIELD WAX INHIBITORS |
摘要 |
Paraffin-containing liquid pour point depressants comprising the reaction product of a hydrocarbyl-substituted phenol and an aldehyde wherein: the olefin used in the preparation of the hydrocarbyl-substituted phenol has a high vinylidene content; the reaction between the hydrocarbyl-substituted phenol and the aldehyde is acid or base catalyzed; and/or the reaction further comprises phenol, are particularly useful for treating crude oils which have an initial pour point of 4°C or higher, decreasing the fluid's pour point and improving the fluid's low temperature handling properties.
