Definitions
- DE-3627432 teaches a brake fluid based on glycols and glycol ethers, consisting essentially of
- a functional fluid composition being essentially free from borates which exhibits superior values of ERBP and of WERBP and for low temperature kinematic viscosity, while maintaining excellent resistance to corrosion, high stability and meeting other physical property requirements such as pH, reserve alkalinity and rubber swell.
- WERBP values are achieved by using ortho esters as a replacement for borate esters.
- R5 is a C 1 - to C 8 -alkyl group and may be methyl, ethyl, n-propyl, isopropyl, n-butyl, isobutyl, sec-butyl, tert-butyl, n-pentyl, n-hexyl, n-heptyl, n-octyl and 2-ethylhexyl, ethyl. More preferably, R5 is ethyl, n-butyl or methyl, most preferably n-butyl or methyl.
- Examples of useful alkoxy glycols for component (B) of the present invention include methyldiglycol, methyltriglycol, methyltetraglycol, methylpentaglycol, methylhexaglycol, ethyldiglycol, ethyltriglycol, ethyltetraglycol, ethylpentaglycol, ethylhexaglycol, n-propyl-diglycol, n-propyltriglycol, n-propyltetraglycol, n-propylpentaglycol, n-propylhexaglycol, n-butyldiglycol, n-butyltriglycol, n-butyltetraglycol, n-butylpentaglycol, n-butylhexaglycol, n-pentyldiglycol, n-pentyltriglycol, n-pentylt
- Percentages of species of component (B) are given in wt.-% with the total amount of component (B) being 100 wt.-%.
- alkanolamines are mono-, di- and trimethanolamine, mono-, di- and triethanolamine, mono-, di- and tri-n-propanolamine and mono-, di- and tri-isopropanolamine.
- suitable alkyl amine ethoxylates are such linear, cyclic or branched alkylamine ethoxylates carrying 1.5 to 5 EO moieties and an alkyl chain having 4 to 18 carbon atoms.
- Component (D) of the present functional fluid composition may comprise, besides the Amine, at least one additive with corrosion inhibition action, although the alkylamine ethoxylates exhibit corrosion inhibition properties themselves.
- suitable customary additives with corrosion inhibition properties include fatty acids such as lauric, palmitic, stearic or oleic acid; esters of phosphorus or phosphoric acid with aliphatic alcohols or aliphatic alcohol ethoxylates; such as ethyl phosphate, dimethyl phosphate, isopropyl phosphate, n-butyl phosphate, 2-ethylhexyl phosphate, triphenyl phosphite and diisopropyl phosphite; heterocyclic nitrogen containing organic compounds such as benzotriazole, tolyltriazole, 1,2,4-triazole, benzoimidazole, purine, adenine and derivatives of such heterocyclic organic compounds.
- the low viscosity functional fluid composition of the present invention is especially useful as a brake fluid, for example for vehicles such as passenger cars and trucks, especially for new electronic or automated anti-lock brake systems which require lower viscosity fluids for satisfactory operation at low temperatures.
- the reaction temperature was increased to 185°C and held for a further 45 minutes, a total of about 83% (71 g, 2.22 mol) of the theoretical amount of methanol being distilled off. Thereafter, a further 211 ml (1.34 mol) of methyl triglycol were metered in at constant heating power, and after one hour the reaction temperature was increased to 225°C and held for one hour, further methanol being distilled off. A further 50 ml (0.32 mol) of methyl triglycol were then metered in at constant heating power, and 1.9 g of benzoic acid were added. After 3 hours, a further 0.9 g and finally another 0.4 g of benzoic acid were added after a further hour.
- Trimethyl ortho acetate (1.8 mol) was reacted with a mixture of 70% triethyleneglycolmonobutylether and 30% tetraethyleneglycolmonobutylether (combined 6.3 mol), resulting in the corresponding product with 88% conversion according to NMR.
- Diisopropanol amine 0.629%, Styrenated diphenyl amine: 0.1%, Castor oil + 20 EO: 0.2%, Silicone based defoamer: 0.001%, Tolyl triazole: 0.06%, Phosphoric acid ester: 0.01%.
