摘要 |
The present invention is directed toward a method for preparing Group II metal overbased sulfurized alkylphenols. In particular, the present invention employs a sulfurization catalyst in the preparation of Group II metal overbased sulfurized alkylphenols. Use of a sulfurization catalyst in this preparation results in a product generally characterized as having lower crude sediment, a higher Total Base Number and lower viscosity than a similar product prepared without using a sulfurization catalyst. |
