Abstract

PROCESSO DE OBTENçãO DE ISOSAFROL E SEUS DERIVADOS A PARTIR DE óLEOS ESSENCIAIS DE PLANTAS DA FAMìLIA PIPERONACEAE, compreende processo de obtenção de isosafrol diretamente a partir de óleos essenciais de plantas da família piperonaceae, sem a necessidade de uma etapa de purificação prévia do safrol, que é abundante nestes óleos; a presente invenção acaba por permitir uma maior proximidade da execução do processo aqui apresentado ao produtor do óleo; o processo apresentado tratado é de fácil manipulação e não oferece riscos de toxidade quando utilizado em uma capela de laboratório; tal processo compreende basicamente as seguintes etapas:) adicionar óleo essencial de plantas da família piperonaceae em um balão de fundo redondo com condensador de refluxo; 2) aquecer e agitar a mistura simultaneamente; 3) quando o óleo essencial começa a entrar em ebulição, retirar o condensador e adicionar KOH e CaO, recolocando posteriormente o condensador de refluxo e manter o aquecimento e a agitação por 15 minutos; 4) após passar os 15 minutos, desligar o aquecimento, e continuar com a agitação por mais 10 minutos; 5) transferir a mistura para um becker ou recipiente equivalente; 6) manter a solução no becker ou recipiente equivalente por, aproximadamente, 1 hora; J) filtrar a solução resultante com, preferencialmente, papel de filtro sob vácuo e depositar a mistura filtrada em outro becker ou recipiente equivalente; 8) lavar as partículas sólidas retidas no papel de filtro com éter; 9) destilar a solução; e 10) colher a solução resultante, que já se trata de isosafrol.ISOSAFROL PROCESSING AND ITS DERIVATIVES FROM ESSENTIAL OILS OF PIPERONACEAE FAMILY PLAN comprises the process of obtaining isosafrol directly from essential oils of the piperonaceae family, without the need for a prior purification step of safrol. It is abundant in these oils; The present invention enables the process of the oil producer to be brought into closer proximity; The treated process presented is easy to handle and offers no risk of toxicity when used in a laboratory chapel; Such a process basically comprises the following steps :) Adding essential oil from plants of the piperonaceae family into a round bottom reflux condenser flask; 2) heat and stir the mixture simultaneously; 3) When the essential oil begins to boil, remove the condenser and add KOH and CaO, then replace the reflux condenser and keep heating and stirring for 15 minutes; 4) After 15 minutes, turn off the heat and continue stirring for another 10 minutes; 5) transfer the mixture to a becker or equivalent container; 6) keep the solution in the becker or equivalent container for approximately 1 hour; J) filtering the resulting solution preferably with vacuum filter paper and depositing the filtered mixture in another becker or equivalent container; 8) washing the solid particles trapped in the filter paper with ether; 9) distill the solution; and 10) collecting the resulting solution, which is already isosafrol.
