Abstract
A process is provided for converting mevalonic acid into various useful products and derivatives. More particularly, the process comprises reacting mevalonic acid, or a solution comprising mevalonic acid, in the presence of a solid catalyst at an elevated temperature and pressure to thereby form various biobased products. The process may also comprise: (a) providing a microbial organism that expresses a biosynthetic mevalonic acid pathway; (b) growing the microbial organism in fermentation medium comprising suitable carbon substrates, whereby biobased mevalonic acid is produced; and (c) reacting the biobased mevalonic acid in the presence of a solid catalyst at an elevated temperature and pressure to yield various biobased products.

A process comprising:
- (a) reacting MVL, or a solution comprising MVL, in the presence of a solid catalyst at a temperature in the range of 50° C. to 500° C. and a pressure ranging from atmospheric pressure to less than 100 bar to yield a first product or first product mixture,
- wherein the first product or the first product mixture comprises isoprene, 3-methyl-2-butanone, methyl vinyl ketone, anhydro-mevalonolactone, 2-pentene, 2-methyl-1-butene, 2-methyl-1-pentene, methane, hydrogen, an alcohol, a carboxylic acid, or combinations thereof,
- wherein the solid catalyst is selected from the group consisting of a mixed metal oxide, a supported transition metal, a supported noble metal, functionalized tetrafluoroethylene-fluoropolymer copolymers, calcium apatite, silica-alumina, silica, titania, sulfated zirconia, alumina, and combinations thereof.
A process comprising reacting MVL in the presence of a silica-containing catalyst at a temperature in the range of 150° C. to 400° C. and a pressure in the range of atmospheric pressure to less than 100 bar to yield a first product comprising isoprene and/or methyl vinyl ketone.
