  • Eco-friendly process for hydrogenation or/and hydrodeoxygenation of organic compound using hydrous ruthenium oxide catalyst
    Patent number: 10954185
    Abstract: The invention discloses a process for hydrogenation (alkenes, carbonyl compounds and aromatics) and hydrodeoxygenation (methoxy phenols) of organic molecules using hydrous ruthenium oxide (HRO) and its supported form as a recyclable heterogeneous catalyst in aqueous medium with good yield of desired products (70-100%) under mild reaction conditions.
    Type: Grant
    Filed: October 7, 2016
    Date of Patent: March 23, 2021
    Assignee: Council of Scientific & Industrial Research
