摘要： DISCLOSED ARE BENZOBISPHOSPHATES OF THE FORMULA:

2,6-DI(Z=),2,6-DI(X-)BENZO(1,2-D:4,5-D'')BIS-1,3,2-

DIOXAPHOSPHOLE

WHEREIN: X REPRESENTS HALOGEN, NR2 WHERE R IS HYHYDROGEN, ALKYL, OR CYCLOALKYL, HAVING UP TO 30 CARBON ATOMS OR ARYL OR ARALKYL HAVING UP TO 22 CARBON ATOMS, PYRROLIDINO, PIPERIDINO OR MORPHOLINO; Z IS OXYGEN OR SLFUR OR MAY BE ABSENT. THESE COMPOUNDS ARE EFFECTIVE AS ANTI-WEAR AND ANTIOXIDANT ADDITIVES FOR LUBRICATING OILS. THEY ALSO HAVE FLAME RETARDANT PROPERTIES.

摘要： PHOSPHOROUS DERIVATIVES OF O-DIHYDROXYBENZENES EFFECTIVE A LUBRICANT ADDITIVES ARE DEFINED BY THE FORMULA:

2-(Z=),2-Y-1,3,2-BENZODIOXAPHOSPHOLE

WHREIN Z REPRESENTS OXYGEN OR SULFUR OR MAY BE ABSENT; Y REPESENTS NHR OR NR2, WHERE R IS ALKYL HAVING UP TO 30 CARBON ATOMS IN THE CHAIN OR ARYL OR ARLAKYL HAVING UP TO 22 CARBONS. THE COMPOUNDS ARE USEFUL IN LUBRICATING COMPOSITIONS WHEN PRESENT THEREIN IN AN AMOUNT RANGING FROM ABOUT 0.01 TO 50 PERCENT BY WEIGHT OF THE COMPOSITION.
