Abstract

Patente de Invenção: "PROCESSO DE PREPARAçãO DOS FLUORO-FORMIATOS ALIFáTICOS". O processo de preparação dos fluoroformiatos alifáticos, de acordo com a invenção, consiste em fazer reagir o fluoreto de carbonila com um álcool alifático em presença de fluoreto de sódio em um éter a uma temperatura de -20<198> a 50<198>C. Em particular, o processo é realizado com o fluoreto de carbonila obtido por reação do fosgênio com um excesso de fluoreto de sódio em pó, cujos grãos têm uma superfície específica superior ou igual a 0,1 m^ 2^/g e/ou um diâmetro médio inferior ou igual a 20 <109>m, a uma temperatura compreendida entre 25<198> e 120<198>C. O processo permite obter os fluoroformiatos instáveis, tal como o fluoroformiato de terciobutila com excelentes rendimentos.
