Abstract:

Three fluoroesters and a polyphenyl ether bisphenoxy-phenoxy- benzene were subjected to oxidizing conditions at 437 to 650 F in the presence and absence of the metals and organometal compounds, and data were obtained to show the oxidation inhibition due to the additive. At 437 F Cu and steel improved the stability of the fluoroalcohol psi-alkyl ester f 3- methylglutaric and camphoric acids. At 482 F, the camphorate was substantially tabilized by Cu, Ba, monel, and Cr by toluates or benzoates of Ba, Ni, Cr, Co, Mn, Pr, Ti, Yb, and Sr by cerium disalicylalpropylene diamine and cerium psiheptyl hydrogen-3-methylglutarate and by the Cu salts of perfluoroundecanoic acid, psi-heptyl hydrogen 3-methylglutarate, toluic acid, and phenylstearic acid. Bispsi-amyl2,2-diphenate possessed generall high inherent stability up to 617 F. At 642 F the ester underwent extensive pyrolysis, which the inhibitors did not prevent. The polyphenyl ether, bisphenoxy-phenoxybenzene, was effectivel protected from oxidation at 600 F by copper, cupric toluate, and ceric toluate. At 650 F effective inhibitors were Ba metal, and the toluates or benzoates of Ba, Mn, Ce, Ni, Pb, Pr, Co, Cr, Ti, Yb. Author
