Abstract
UN CARBONATO DE DIARILO SE PRODUCE POR DESCARBONILACION DE UN OXALATO DE DIARILO, EL CUAL SE PUEDE PREPARAR POR TRANSESTERIFICACION DE UN OXALATO DE DIALQUILO CON UN COMPUESTO DE HIDROXIARILO, EN PRESENCIA DE UN CATALIZADOR, A LA VEZ QUE SE ELIMINA EL MONOXIDO DE CARBONO RESULTANTE COMO SUBPRODUCTO Y A CONTINUACION REFINAR OPCIONALMENTE MEDIANTE UNA EVAPORACION Y/O DESTILACION, POLIMERIZANDOSE A CONTINUACION EL CARBONATO DE DIARILO RESULTANTE POR CONDENSACION CON UN COMPUESTO POLIHIDROXILO A LA VEZ QUE SE RECUPERA UN COMPUESTO DE HIDROXIARILO RESULTANTE A PARTIR DEL SISTEMA DE REACCION OBTENIENDOSE UN POLICARBONATO.
