    • Process for preparing high overbased metal sulfurized alkylphenates, wherein a majority of the alkalinity is provided by at least a stoichiometric excess of metal. The process is characterized by a sulfurization reaction using a promoter, followed by overbasing with carbon dioxide, a polyamine, and additional metal base in the presence of an alkylene glycol under reactive conditions at temperatures in the range of about from 150.degree. C. to 190.degree. C. The process affords a metal sulfurized phenate product which is substantially insensitive to overcarbonation, which exhibits low corrosive wear, and which exhibits high rates of acid neutralization. These compositions are useful in the formulation of marine cylinder lubricants.
    • 制备高碱性金属硫化烷基酚盐的方法,其中大部分碱度由至少化学计量过量的金属提供。 该方法的特征在于使用促进剂的硫化反应,随后在反应条件下在约150℃至190℃的温度范围内在亚烷基二醇存在下,用二氧化碳,多胺和另外的金属碱进行高碱性化 该方法提供对过度碳酸化基本上不敏感的金属硫化酚盐产物,其表现出低腐蚀性磨损,并且其表现出高的酸中和速率。 这些组合物可用于制备船用润滑油。
