  The present invention relates to a process for preparing ethers, particularly unsymmetrical ethers, and preferably ethers suitable for use as base stocks for lubricant compositions. In particular, the process involves the reaction of an α,β-unsaturated aldehyde with a trihydrocarbyl orthoester to form an α,β-unsaturated acetal and conversion of the α,β- unsaturated acetal to an ether through hydrogenation and hydrogenolysis.

  本发明涉及一种制备醚的方法，特别是不对称醚，且最好适用于作为润滑剂配方基础油的醚。具体而言，该方法涉及将α，β-不饱和醛与三烷基正酯发生反应，形成α，β-不饱和缩醛，并通过加氢和氢解将α，β-不饱和缩醛转化为醚。

  The present invention relates to a selective process for preparing acetals or ethers. In particular, the process involves a selective catalytic hydrogenolysis of a trihydrocarbyl orthoesterso as to control the extent of dealcoholation to afford either the corresponding acetal or ether product. Ether products preparable by means of the present invention include ethers which are suitable for use as base stocks in lubricating compositions.

  本发明涉及一种选择性过程，用于制备缩醛或醚。具体而言，该过程涉及对三烷基正酯进行选择性催化氢解，以控制去醇化的程度，从而制得相应的缩醛或醚产品。通过本发明可制备的醚产品包括适用于润滑剂组合中作为基础油的醚。

  The use as an anti-wear additive and/or friction modifier in a non-aqueous lubricant composition and/or in a fuel composition of at least one long chain fatty acid ester of a hydroxy carboxylic acid in which the long chain fatty acid has at least 4 carbon atoms and the ester is an oil-soluble ester of a mono- or poly-hydroxy carboxylic acid having 1 to 4 groups which are independently carboxylic acid groups or lower hydrocarbyl esters thereof and in which, when the hydroxy carboxylic acid is a mono-hydroxy carboxylic acid, the ester has a long chain fatty acid ester moiety of the hydroxy group of the hydroxy carboxylic acid and, when the hydroxy carboxylic acid is a poly-hydroxy carboxylic acid, the ester has independently long chain fatty acid ester moieties of one or two of the hydroxy groups of the poly-hydroxy carboxylic acid. Also, a non-aqueous lubricant composition and a fuel composition for an internal combustion engine which comprises at least one of said long chain fatty acid esters.
