Thermal behavior of a mixture of fullerenes and fullerites C60/70

Abstract

The thermal behavior of a mixture of fullerites C 60/70 was studied by X ray diffraction and IR and UV spectroscopy. The temperature range in which the molecular and crystal states degrade was determined (825-875°C in a CO medium). In the C 60/70 mixture, fullerenes decomposed at lower temperatures than in pure C 60 and C 70 ; the decomposition temperature depended on the impurity (oxygen and solvent) content.

Fullerene C60 Derivatives as High-Temperature Inhibitors of Oxidative Degradation of Saturated Hydrocarbons

“…Unfortunately, poor solubility in almost all solvents is a major barrier limiting the applicability of C 60 ; there are a few reports concerning solubility of fullerenes in lipids (for example, 909 mg/L for olive oil), − and in order to increase their solubility, some polar groups have to be attached. , The carbon sphere can be a good starting structure for design and development of new radical-scavenging compounds with specific functionalities. Thermally stable (up to 600 °C) C 60 molecule can trap several radicals − and can potentially be used as protective substance against reactive oxygen species, ROS. , There are several reports concerning potential antioxidant activity of C 60 . − Our previous work described the antioxidant behavior of C 60 during the autoxidation of stearic acid (STA) over a wide range of temperatures, as a noncorrosive agent for effectively increasing the oxidative stability of lubricants . There is some experimental evidence that fullerene derivatives might also be active antioxidants.…”
