Definitions

• the present invention relates to lubricating compositions; more particularly it concerns lubricating composi- CH B tions containing a lubricant, especially a lubricant based on minenal oils, and an aryl-glycide ether of the general fl- 2 63 formula (311E R on: on,
• R stands for an alkyl radial containing at least E7 58 12 carbon atoms.
• Suitable aryl-glycide ethers are for instance 4-dodecylphenoxy-p-ropene oxide, 4-is0dodecyl-phenoxy-propene 12 iso @-O-GH1-CH OH; 31 oxide, 3-pentadecyl-phenoxy-propene oxide, 4-octadecylphenoxy-propene oxide and 4-isooctadecyl-phenoxy-prm 25 P6116 oxide.
• 4-dodecylphenoxy-p-ropene oxide 4-is0dodecyl-phenoxy-propene 12 iso @-O-GH1-CH OH; 31 oxide, 3-pentadecyl-phenoxy-propene oxide, 4-octadecylphenoxy-propene oxide and 4-isooctadecyl-phenoxy-prm 25 P6116 oxide.
• Aryl-glycide ethers of this type are obtainable by various methods, e.g. by reacting epichorohydrin with phe- 1101s which are substituted by an alkyl radical containing at least 12 carbon atoms, or by epoxylating the corre- 76 sponding arylallyl ethers; in general, they are viscous, colourless or slightly coloured, odourless liquids.
• the aryl-glycide ethers present in the lubricating compositions of the invention increase mainly the thermal We claim: stability of the lubricants to which they impart good 35 A lubflcatlPg composltlon comprlsm'g mal0T high-pressure properties as well as detergent action; morep of a lubncant and 014% by Welght of an n over, it is remarkable that they are compatible with glyclde ether of the general formula other lubricant additives such as antioxidants or anti- 3 corrosion agents.
• the requisite quantities of aryl-glycide ethers may readily be established by preliminary 40 gexperiments; in general, an addition of 0.1 to 5 percent by weight, referred to the lubricant, is sufiicient.
• a lubricating composition comprising a major Ar-0-oH, oHoH, amount of a mineral oil lubricant and 0. 1-5 by weight of 4-isododecyl-phenoxy-propene oxide.
