The present invention relates to a process for continuous production of C4-C10 Diols from C3-C9 aldehydes comprising the process steps of: a) base-catalyzed addition of formaldehyde onto C3-C9 aldehydes to obtain the corresponding hydroxyaldehydes and b) subsequent hydrogenation of the hydroxyaldehydes to afford the corresponding diols, wherein the hydrogenation of the hydroxyaldehydes is performed continuously in the liquid phase over a Raney™ cobalt catalyst in the presence of hydrogen without workup of the reaction mixture from the process step a).

The present invention relates to the use of esters of octahydro-4,7-methano-1H-indene-5-methanol (TCD-M) or -dimethanol (TCD-DM) and aliphatic C2-C18 monocarboxylic acids as lubricants in low temperature applications. In addition, the present invention relates to low-temperature lubricant compositions comprising said esters.
