Abstract

processo de obtenção de espilantol. o presente certificado de adição se insere no campo da química/engenharia química, mais especificamente à área de síntese orgânica, e descreve um processo de obtenção de espilantol a partir de seu análogo, em que foi alterada a ordem da etapa de redução de alcinos de forma z seletiva para o final da síntese. ao reduzir o intermediário e o análogo do espilantol formado, o rendimento total do processo apresentou um incremento em torno de 4% e diminuiu a produção de resíduos sólidos metálicos. adicionalmente, foi reduzida a quantidade de material utilizado no processo utilizando um catalisador disponível comercialmente e que pode ser reciclado.process of obtaining spilantol. this certificate of addition is inserted in the field of chemistry / chemical engineering, more specifically in the area of organic synthesis, and describes a process of obtaining spilantol from its analogue, in which the order of the step of reduction of alkyds of selective z form for the end of the synthesis. by reducing the intermediary and the analogue of the formed spilantol, the total yield of the process increased by around 4% and decreased the production of solid metallic waste. in addition, the amount of material used in the process was reduced using a commercially available and recyclable catalyst.
