Abstract

"PROCESSO PARA AUMENTAR A ESTABILIDADE à OXIDAçãO DE BIODIESEL". A invenção refere-se a um processo para aumentar a estabilidade à oxidação de biodiesel, que se destaca pelo fato, de que um antioxidante primário com um ponto de fusão menor igual a 40<198>C é acrescentado ao biodiesel a ser estabilizado em uma quantidade de 10 até 20000 ppm (w/w), sendo que o antioxidante primário apresenta pelo menos um composto de acordo com a estrutura com: R~ 1~, R~ 2~ representam hidrogênio, grupo alquila linear com um número de átomos de carbono de 1 até 20 ou sendo que representa um átomo de carbono do sistema de anel aromático, R~ 3~, R~ 5~ representam hidrogênio, grupo alquila linear com um número de átomos de carbono de 1 até 20, R~ 4~ representa hidrogênio, grupo alquila linear com um número de átomos de carbono de 1 até 40, sendo que tanto os substituintes do tipo R~ 1~ e R~ 2~, quanto também do tipo R~ 3~ e R~ 5~ são iguais ou diferentes."PROCESS TO INCREASE STABILITY TO BIODIESEL OXIDATION". The invention relates to a process for increasing the oxidation stability of biodiesel, which stands out for the fact that a primary antioxidant with a melting point of less than 40 <198> C is added to the biodiesel to be stabilized in a biodiesel. 10 to 20,000 ppm (w / w), the primary antioxidant having at least one compound according to the structure having: R 1, R 2 represent hydrogen, linear alkyl group having a number of atoms of carbon of 1 to 20 or of which represents a carbon atom of the aromatic ring system, R 3 -, R 5 - represent hydrogen, linear alkyl group having a number of carbon atoms from 1 to 20, R 4 - represents hydrogen, linear alkyl group having a number of carbon atoms from 1 to 40, wherein both the substituents of the type R 1 and R 2, as well as the type R 3 and R 5 are the same. or different.
