example 2
[0040] The preparation process of high alkali value (TBN300) sulfurized alkylphenate calcium is as follows:
[0041] In a system containing solvent and diluent oil, combine (a) alkylphenolic compound, (b) shielded phenolic compound with (c) calcium oxide and / or calcium hydroxide, (d) sulfur, (e) alkyl The mixture of polyhydric alcohol and (f) long-chain carboxylic acid undergoes vulcanization and neutralization reaction to generate phenate intermediate. Among them, the alkylphenol compound is a monosubstituted phenol, the R group of the alkylphenol contains at least nine carbon atoms, including nine carbon atoms to twenty-one carbon atoms, and the R group is a straight-chain or branched saturated hydrocarbon Structure, nonylphenol, dodecylphenol, pentadecylphenol, octadecylphenol or hexadecylphenol can be selected for use, and dodecylphenol is selected in this example. Shielded phenolic compound refers to the compound that there is a branched chain substituent from three carb...
