  • One-pot production of carbamates using solid catalysts
    Patent number: 8765993
    Abstract: The invention relates to the production of carbamates in a single reactor (one-pot) using solid catalysts, involving the reaction between at least one nitro compound, an organic carbonate of formula (OR)(OR?)C?O, a gas selected from hydrogen gas and a mixture of gases containing hydrogen and hydrogen precursor compounds, and a catalyst that has at least one metallic oxide and can also contain an element of groups 8, 9, 10 and 11 of the periodical table. The carbonates obtained can be transformed into their corresponding isocyanates.
    Type: Grant
    Filed: September 9, 2011
    Date of Patent: July 1, 2014
    Assignees: Consejo Superior de Investigaciones Cientificas, Universidad Politecnica de Valencia

  • Preparation of carbamates with solid catalysts
    Patent number: 8735621
    Abstract: Carbamate preparation process comprising, the reaction between at least: an amine or polyamines, an organic carbonate of formula (OR)(OR?)C?O, a catalyst which is formed by at least a support selected from at least a metal oxide, a microporous material, a mesoporous material, an anionic laminar compound of hydrotalcite type or their derivatives or an organic polymer and which may further contain a metal from groups 8, 9, 10 and 11 of the periodical system. The carbonates obtained can be transformed in their corresponding isocyanates.

  • Process for producing fluorinated carbamates and isocyanates
    Publication number: 20090082588
    Abstract: The invention relates to a process for producing fluorinated carbamates comprising the reaction between an amine or polyamine and a fluorinated carbonate, in the presence of a catalyst which does not contain metals and comprises at least one tertiary amine group. The process can also comprise an additional step in which the carbamates are transformed into the corresponding isocyanates.
