Page/Page column 6, (2011/05/08)
Procedure for preparing carbamates comprising reaction between at least: an amine or polyamines, an organic carbonate of formula (OR)(OR')C=O, a catalyst formed at least by a support selected from among at least a metal oxide, a microporous material, a mesoporous material, an anionic laminar compound of the hydrotalcite type or derivatives thereof or an organic polymer and which may also contain a metal from groups 8, 9, 10 and 11 of the periodic system. The carbamates obtained may be converted into the corresponding isocyanates thereof.

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.
