The DSC cell—a versatile tool to study thermal-oxidative degradation of lubricants and related problems

Fate of amine antioxidants during thermal oxidative ageing of neopentylpolyol ester oils: Part 1

“…Very Generally, primarily formed aminyl radicals are converted in the presence of hydroperoxides, peroxy radicals and peracids into nitroxyl radicals, for example (7)- (9), or (10)-(11):…”

Fuel Properties and Performance of Biodiesel

“…P -DSC has the added advantage of providing elevated pressures which increases the total number of moles of oxygen available for reaction. These techniques have been applied to the analysis of petrochemical and synthetic lubricants, biodegradable lubricants, aviation turbine oils and polymers (Sharma and Stipanovic, 2003 ;Gamelin et al , 2002 ;Riga et al , 1998 ;Yao, 1997 ;Zeman et al , 1995 ;Patterson and Riga, 1993 ;Zeman et al , 1993 ;Kaufman and Rhine, 1988 ;Zeman et al , 1984 ;Walker and Tsang, 1980 ;Noel, 1972 ) as well as edible fats and oils, air -blown vegetable oils, epoxidized soybean oil, genetically modifi ed soybean oil and alcohol -based fuels (Adhvaryu and Erhan, 2002 ;Kenar et al , 2002 ;Tan et al , 2002 ;Adhvaryu et al , 2000 ;Kowalski et al , 2000 ;Perez, 2000 ;Litwinienko and Kasprzycka -Guttman, 1998 ;Litwinienko et al , 1995 ;Kasprzycka -Guttman et al , 1995 ;Kowalski, 1995 ;Hassel, 1976 ;Cross, 1970 ).…”
