Definitions
- This invention relates to stabilising compositions for lubricant base stocks and lubricant formulations.
- lubricant base stocks such as mineral and synthetic base oils chosen from Group I, Group II, Group III, Group IV and Group V base stocks as classified by the American Petroleum Institute, as well as natural and synthetic esters including polyol esters, more particularly, but not limited to automotive oils, circulatory oils, gear oils, greases, hydraulic fluids, turbine fluids and metal working fluids.
- lubricant formulations is meant a lubricant base stock as described above, plus additional additives including but not limited to antioxidants, rust inhibitors, metal passivators, ashless dispersants, antiwear additives, extreme pressure additives and detergents, viscosity index improvers and antifoam agents.
- a stabilising composition for lubricant base stocks and lubricant compositions comprises:
- R 1 and R 2 are the same or different and may be H, an alkyl group with 4 to 9 carbon atoms or an aralkyl group with 8 carbon atoms and m and n are 0 to 2 but m+n is not greater than 3, either alone or optionally blended with at least one hindered phenolic antioxidant selected from those corresponding to one of the following general formulae:
- R 3 , R 4 , R 5 and R 6 are the same or different and may be an alkyl group with 1 to 4 carbon atoms and X is —S— or —CH 2 — or —CH 2 CH 2 —S—CH 2 CH 2 — or —CH 2 —S—CH 2 — or —CH 2 CH 2 CO 2 CH 2 CH 2 —S—CH 2 CH 2 CO 2 CH 2 CH 2 —

- R 8 , R 9 and R 10 are the same or different and may be H, CH 3 , isopropyl or tertiary butyl and m is 0 to 2;
- R 11 , R 12 and R 13 are all the same and are alkyl groups with 4 to 12 carbon atoms;
- R 14 is different from R 15 and R 16 and R 14 is an alkyl group with 4 to 12 carbon atoms and R 15 is phenyl or substituted phenyl with 7 to 10 carbon atoms and R 16 may be an alkyl group with 4 to 12 carbon atoms or phenyl or substituted phenyl with 7 to 10 carbon atoms;
- R 17 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;
- R 18 , R 19 , R 20 are the same or different and are H or alkyl with 1 to 9 carbon atoms;
- R 21 , R 22 and R 23 are the same or different and are alkyl groups with 1 to 18 carbon atoms.
- R 24 and R 25 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 27 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, m 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).
- Examples of 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.

- Examples of formula VIII compounds are dipentyl hydrogen phosphate; di C 10-12 alkyl-hydrogen phosphate; C 10-12 alkyl-dihydrogen phosphate.
- An Example of formula IX 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 components of the mixtures of the invention can be tailored to provide the required performance characteristics in terms of stability, in a particular base stock and/or lubricant formulation.
- 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.
