Title:
METHOD OF INHIBITING DEGRADATION OF PHOSPHATE ESTER OIL AND APPARATUS FOR INHIBITING DEGRADATION OF PHOSPHATE ESTER OIL
Document Type and Number:
Japanese Patent JP2018062598
Kind Code:
A
Abstract:
PROBLEM TO BE SOLVED: To provide a method of inhibiting degradation of phosphate ester oil that is able to inhibit degradation of phosphate ester oil, and an apparatus for inhibiting degradation of phosphate ester oil.SOLUTION: It is possible to inhibit degradation of phosphate ester oil by supplying active hydrogen from a hydrogen supplying module 13 to phosphate ester oil that comprises phenol derivatives produced by storage or usage of the oil and quinones that have been derived from phenol derivatives and hydrogenating the quinones. Namely, an amount of quinones in the phosphate ester can be reduced because the quinones can be restored to phenol derivatives by hydrogenating and reducing the quinones. Consequently, degradation of phosphate esters can be inhibited because polymerization due to a reaction of the phenol derivatives with the quinones is prevented.SELECTED DRAWING: Figure 1
