A Crenewable base oil is disclosed that is suitable as a base oil to provide low viscosity base oils, such as having both low Noack volatility and low CCS-30&#xb0; C. viscosity and/or to provide low viscosity base oils at the same time having a combination of acceptable HTHS and KV100 to allow the industry's base oil blenders to formulate high quality engine oils, such as SAE grade 0W-20, 0W-16, 0W-12 or 0W-8.

Renewable base oil in lubricant formulations

The present invention relates to a process for producing polyolefins wherein a feedstock comprising n-olefin or a mixture of n-olefins is dimerized in the presence of a solid acidic catalyst by passing the feedstock to a catalytic distillation apparatus comprising either a) a combination of a distillation column and a reactor comprising at least one catalyst bed, or b) a distillation column connected to one or more side reactors comprising at least one catalyst layer, recovering the unreacted n-olefin from the distillation column or the combination of the distillation column and the reactor at the upper part thereof as a side-stream to be combined with the feedstock, and the reaction product from the dimerization is hydrogenated.

The present invention concerns a process for producing 2-butyl-2-ethyl-1,3-propanediol. According to the process, a reaction mixture is formed, containing 2-ethylhexanal and formaldehyde, into which an hydroxide compound is fed, whereby 2-ethylhexanal and formaldehyde are reacted to to produce 2-butyl-2-ethyl-1,3-propanediol. According to the invention, the hydroxide compound is incrementally fed into the reaction mixture. Preferably the hydroxide compound is fed at least at two input rates, in such a way that the heat production of the reaction between 2-ethylhexanal and formaldehyde immediately after each increase of the input rate of the hydroxide compound, is at least almost the same. The invention allows for the production of BEPD in a controlled and safe manner, with excellent yields.
