- the phosphomolybdenum compound 4 of the present invention obtained as described above was washed three times with n-hexane and water and then desolvated under reduced pressure to increase the degree of purification. Structural analysis was performed using phosphomolybdenum compound 4:
- the molybdenum content in the phosphomolybdenum compound 4 after purification is increased. This is because the acidic phosphate ester that is not bound to the molybdenum atom is removed by purification, the total amount of the compound is reduced, the molybdenum content is relatively increased, and the purification results in unbound acidic phosphate acid ester. Since the phosphorus atom is removed, it is assumed that there is no change in the phosphorus content. From the results of the above elemental analysis, it can be confirmed that the molybdenum atom and the phosphorus atom exist in equimolar amounts. Since the molybdenum and phosphorus atoms are equimolar and the molybdenum atom is reduced to pentavalent !, the following structure is considered to form the basic skeleton.
- TOF-MS analysis is based on a time-of-flight mass spectrometer, which ionizes a sample, flies a certain distance, and measures the time of flight to determine the molecular weight.

- Molybdenum atoms have many isotopes, and even among those isotopes, the abundance ratio is prominent and many are V.
- the main atomic weights and their proportions are as follows:
- TOF—MS analysis recognizes different peaks even if they have different molecular weights. Therefore, in the chart of compounds containing molybdenum, peaks with a molecular weight of 1 appear.
- the chart shown in Figure 3 shows the force that is the result of TOF—MS analysis. If you look closely, the molybdenum-specific peak was only around 1800 molecular weight. Since there is no peak with a larger molecular weight, it is considered that this is the phosphomolybdenum compound 4 analyzed.
- the peak appearing at a low molecular weight is a peak of phosphate ester or the like obtained by decomposition of the phosphomolybdenum compound 4.
- the chart shown in FIG. 4 is an enlargement of the molecular weight around 1800 of the chart shown in FIG.
- the force that two peak groups peculiar to molybdenum atoms can be seen Since the difference in molecular weight between the two groups is 39, it can be seen that the group on the right is the one with potassium added to the group on the left. Therefore, the left group is the molecular weight of phosphomolybdenum compound 4.
- the molecular weight of the largest peak in the left group is about 1797, which is exactly four times the molecular weight of the basic skeleton obtained from elemental analysis.
- molybden atoms ring alternately with oxygen atoms, resulting in the following structure:

- the autoclave was placed in a thermostatic chamber at 70 ° C and shaken 70 times at Z minutes, sampled after 4 hours, and the remaining amount of CHP was analyzed by measuring the peroxy acid price. CHP remaining is expressed as a percentage of the initial CHP added.
- CHP generates phenol by ionic decomposition, and generates various kinds of radicals by radical decomposition, such as amyl alcohol alcohol acetophenone. Since the generation of radicals is not preferable from the viewpoint of preventing oxidation, the higher the amount of phenol generated, the better the performance of the antioxidant.
- the base oil used is the same as the mineral oil based advanced VI oil used in ⁇ Measurement of Sludge> above.

Value).
- the smaller the increase in the total acid value the higher the acidity stability. In this test, if the increase in the total acid value exceeds lOmgKOHZg, it is difficult to use as a normal engine oil.
