With a total of three patents to his name, Lehtinen's work has had a considerable impact on the industry.

Latest Patents

Lehtinen's latest patents include a process for the manufacture of polyolefins. This invention relates to a method of producing polyolefins by dimerizing a feedstock comprising n-olefins in the presence of a solid acidic catalyst. The process utilizes a catalytic distillation apparatus, which can either be a combination of a distillation column and a reactor or a distillation column connected to side reactors. The unreacted n-olefin is recovered as a side-stream, and the dimerization product is subsequently hydrogenated.

Another significant patent is for the production of 2-butyl-2-ethyl-1,3-propanediol. This process involves forming a reaction mixture containing 2-ethylhexanal and formaldehyde, into which a hydroxide compound is incrementally fed. This controlled feeding allows for the safe production of BEPD with excellent yields.
