- the present invention relates to a method for producing a metal class phenylate concentrate.
- Alkali earth metal phenate is a major additive used in lubricating oil for internal combustion engines.It mainly neutralizes acidic substances generated by the combustion of fuel in internal combustion engines to corrode metals. It is used for the purpose of suppressing the deterioration of the lubricating oil, and at the same time, promoting the dispersion of sludge and its precursors in the oil to suppress sticking and wear of engine parts. For this purpose, heat resistance, cleanliness at high temperatures, and oil solubility are important, and sulfurization of alkylphenol is a well-known technique for improving these properties.
- the base number is an index of the acid neutralizing ability. The larger this value is, the higher the acid neutralizing ability of the additive is.
- the alkali metal having an amount of 1 Z 2 mol or more of alkyl phenol is used. Those containing earth metal ions are called "overbased" alkaline earth metal funinates.
- the present inventors have, as a method of solving the problem, to produce an overbased alkaline sulfide alkaline metal sulfide using an excess amount of alkylphenol relative to the alkaline earth metal reagent.
- water that should be removed to the outside of the system before carbon dioxide treatment is a factor that reduces the stability of the phenate in the prior art by removing excess water from the intermediate product after the completion of the metal sulfide addition reaction. It proposes a method of distilling off the alcohol and water of reaction and then treating in a specific amount in the presence of carbon dioxide, and a method of adding a specific amount of fatty acids before carbon dioxide treatment.
- alkaline earth metal phenotype additives are used as additives having high hydrolysis stability, but they are used as lubricating oils (base number 30 mg K 0 H / g), and when the test was performed without using a copper catalyst in the hydrolysis stability test method specified in ASTMD 2619-88, the base number retention after 24 hours was about 30%.

It can be considered that the same is true for alkaline earth metal phenate. Therefore, there is a problem that accurate judgment cannot be made even when considering to obtain a more excellent overbased alkali sulfide alkaline earth metal phenate.
