Abstract

"PROCESSO PARA PREPARAR COMPOSTOS DE CARBAMATO SUBSTANCIALMENTE ISENTOS DE SUBPRODUTOS, E, COMPOSTO DE CARBAMATO". Esta divulgação é um método para a preparação de compostos de carbamatos substancialmente isentos de subprodutos; sendo os compostos de carbamatos preparados pela reação de um isocianato com um composto hidroxilado na presença de certos catalisadores que aumente a velocidade da carbamilação ao mesmo tempo que diminui a velocidade de formação de subprodutos.
