摘要： The present disclosure provides a method for preparing a sulfurized alkyl phenate product to achieve a high sulfurization ratio of sulfurized alkyl phenate to unsulfurized alkyl phenate/phenol in the context of a neutralized and optionally overbased additive. The sulfurized alkyl phenate product is obtained by sulfurizing an alkyl phenol with a sulfur chloride blend that includes about 40 to about 75 weight percent of sulfur dichloride.
