- R 1 is an alkyl group with 5 to 12 carbon atoms and m is 1 or 2 and n is 1 or 2 but m+n is not greater than 3; (v) neutral triaryl phosphites :
- R 18 , R 1 , R20 are the same or different and are H or alkyl with 1 to 9 carbon atoms;
- R 21 , R 2 2 and R 23 are the same or different and are alkyl groups with 1 to 18 carbon atoms.
- R 24 and R 2 are the same or different and are alkyl groups with 1 to 12 carbon atoms or R 24 is phenyl or substituted phenyl where R 26 is alkyl with 1 to 9 carbon atoms.
- R 2 may be an alkyl group with 4 to 18 carbon atoms, phenyl or substituted phenyl with 7 to 10 carbon atoms and m is 1 or 2, n is 1 or 2 but m + n is not greater than 3, and wherein the antioxidants and the phosphate(s) and/or phosphite(s) are utilised in a weight ratio from 10:1 to 1:10, preferably 1:1 to 1:5.
- the stabilising composition is prepared by heating the antioxidant(s) and the phosphate(s) and/or phosphite(s) for 0.2 to 6 hours at a temperature range of 40°C to 150°C.
- the treat rates of the antioxidant(s) and the phosphate(s) and/or phosphite(s) in the lubricant base stocks and lubricant compositions preferably are within the following weight ranges:
- the amine and hindered phenol antioxidants are used at 0.5 to 2.0% each.
- the neutral alkyl, aryl and alkyl aryl phosphates and phosphites are used at 0.5 to 4%.
- the acid phosphates and phosphites at 0.025 to 0.05% (when used together with the neutral phosphates).
- formula I compounds are 4-tert-butyl, 4'-tert-octyl diphenylamine; 4,4'- di-tert-octyl diphenyl amine and 4,4'-di-iso-nonyl diphenylamine.
- formula II compounds are 4,4'-methylene bis (2,6 ditertiary butyl phenol); 2,2' thiodiethylene bis [3-(3,5-di-tert-butyl-4-hydroxy-phenyl) propionate]; 4,4'-thiobis (2-t-butyl-5-methyl phenol); 6,6'-thiobis (2-methyl-4-t-butylphenol).
- Examples of formula III compounds are C 7 . alkyl ester of 3,5-di-tert-butyl-4-hydroxy benzene-3-propionic acid; C ⁇ e alkyl ester of 3,5-di-tert-butyl-4-hydroxybenzene-3- propionic acid.
- An Example of formula IN compounds is pentaerythritol tetra ester of 3,5 di-tert-butyl- 4-hydroxy benzene-3-propionic acid.
- Examples of formula N compounds are tri-dimethyl phenyl phosphate; tri-isopropyl phenyl phosphate; mono-phenyl-di (-tert-butyl phenyl) phosphate.
- Examples of formula NI compounds are tributyl phosphate; trioctyl phosphate.
- Examples of formula VII compounds are octyldiphenyl phosphate; dibutyl-mono-phenyl phosphate.
- N ⁇ i compounds dipentyl hydrogen phosphate; di C 10 - 12 alkyl- hydrogen phosphate; C 10-1 2 alkyl-dihydrogen phosphate.
- An Example of formula LX is tris nonyl phenyl phosphite.
- Examples of formula X are trilauryl phosphite; trioctyl phosphite.
- Examples of formula XI are decyl diphenyl phosphite; didecyl monophenyl phosphite.
- Examples of formula XII are dibutyl hydrogen phosphite; dioctyl hydrogen phosphite; cetyl stearyl hydrogen phosphite.
- lubricant base stocks and lubricant formulations can have varying levels of stability dependent on:
- the Table shows the relative oxidation stability results obtained by adding certain antioxidant(s) and phosphate(s) and/or phosphite(s) mixtures to Group III base stocks.
- the relative oxidation stabilities of the lubricant base stock is determined by the rotating bomb oxidation stability test (RBOT), IP test method number 229.
- the oxidation stability is defined as the number of minutes required to effect a reduction in oxygen pressure of 25.4 PSI or 1.75 bar when the oil and additives are heated at 150°C in an oxygen pressurised vessel.
