Abstrakt: 1.The separation of alkylphenol additives from oil by the use of a rubber membrane is an extremely effective method. With optimum dialysis conditions (for an 8-h period), oil removal from alkylphenol additives is essentially complete. Depending on the nature of the additive, the additive loss during dialysis (dialyzability) will range from 1 to 4% for basic additives and from 3.5 to 12% for neutral additives.2.It has been established that additive composition is essentially unchanged during the dialysis process.3.The dialyzability of alkylphenol additives can serve as a criterion of the colloidal nature of additive-oil solutions.
