MUMBAI, India, June 13 -- Intellectual Property India has published a patent application (202517049524 A) filed by Basf Se, Ludwigshafen am Rhein, Germany, on May 22, for 'process for the manufacture of isononanol from renewably-sourced ethanol.'
Inventor(s) include Willersinn, Stefan; Kindler, Alois; Weinel, Christian; Keck, Daniel; Mackewitz, Thomas; Rahn, Dieter; and Eller, Johannes Lazaros Friedrich.
The application for the patent was published on June 13, under issue no. 24/2025.
According to the abstract released by the Intellectual Property India: "A process for the manufacture of isononanol, comprises subjecting a feedstock comprising a renewably-sourced ethanol to dehydration to produce a renewably-sourced ethylene stream. The renewably-sourced ethylene stream is subjected to an olefin-interconversion to obtain a renewably-sourced C4-olefin stream, the renewably-sourced C4-olefin stream comprising n-butenes, isobutene or a mixture of n-butenes and isobutene. The olefin-interconversion comprises (i) and, where required, (ii), or (ii) and (iii): (i) ethylene dimerization to obtain n-butenes; (ii) isomerization of n-butenes obtained according to (i) to obtain isobutene; (iii) blending n-butenes obtained according to (i) with isobutene obtained according to (ii). The renewably-sourced C4-olefin stream is subjected to a sequence of chemical conversions to obtain isononanol, comprising: oligomerizing the renewably-sourced C4-olefin olefin stream to produce dibutenes; subjecting the dibutenes to a hydroformylation reaction with syngas to obtain isononanal; and hydrogenating the isononanal to produce isononanol. The process provides a reaction scheme for renewably-sourced isononanol."
The patent application was internationally filed on Oct. 27, 2023, under International application No.PCT/EP2023/080096.
