A friend and I are doing a project that involves the process behind manufacturing Jet A-1 and specifically the specifications highlighted in DEF 91-91. I was interested to see the information at the bottom of page 8.
- Why are 2,6-ditertiary-butyl-phenol, 2,6 ditertiary-butyl-4-methyl-phenol and 2,4-dimethyl-6-tertiary-butyl-phenol used rather than "more common" antioxidants like ascorbic acid?
- How do these antioxidants function and do they work any differently to biochemical antioxidants?
- What factors determine the effectiveness of an antioxidant?
- Why are a mixture of chemicals used at different ratio's rather than just one. Do they work more/less effectively at different temperatures for example?
