1 - 5 . (canceled) 
     
     
         6 . A lubricant containing between 20 and 99.9% by mass of one or more compounds of the general formula 1 
       
         
           
           
               
               
           
         
       
       wherein
 X denotes H, F, Cl, —CH 3 , —C 2 H 5 , —OCH 3 , 
 R 1  respectively denote independently of each other H, an alkyl residue having a total of between 1 and 18 C-atoms, in which also one or two non-adjacent CH 2  groups can be replaced by —O—, —S— or —CO— and two adjacent CH 2  groups can be replaced by —COO— or —OOC—, 
 R 2  respectively denote independently of each other an alkyl residue having a total of between 1 and 18 C-atoms, in which also one or two non-adjacent CH 2  groups can be replaced by —O—, —S— and two non-adjacent CH 2  groups can be replaced by —COO— or —OOC—, or the residue 
 
       
         
           
           
               
               
           
         
       
       with the above-specified significances for X and R 1  and wherein n is a number between zero and 12 and q is zero or 1. 
     
     
         7 . A lubricant as set forth in  claim 6  wherein it contains between 50 and 99.9% by mass of one or more compounds selected from the keto compounds of general formula 1. 
     
     
         8 . A lubricant as set forth in  claim 6  wherein it contains between 70 and 99.9% by mass of one or more compounds selected from the keto compounds of general formula 1. 
     
     
         9 . A method for reducing frictional losses between mutually moved solid bodies comprising interposing a compound according to  claim 6  between the solid bodies. 
     
     
         10 . A method for reducing frictional losses between mutually moved solid bodies comprising interposing a compound according to  claim 7  between the solid bodies. 
     
     
         11 . A method for reducing frictional losses between mutually moved solid bodies comprising interposing a compound according to  claim 8  between the solid bodies. 
     
     
         12 . A bearing containing a lubricant according to  claim 6 . 
     
     
         13 . A bearing containing a lubricant according to  claim 7 . 
     
     
         14 . A bearing containing a lubricant according to  claim 8 .
