Abstract
"COMPOSIçãO DE ADITIVO PARA COMBUSTìVEIS LìQUIDOS" A presente invenção se refere a uma composição de aditivo para combustíveis líquidos mistos, a saber, contendo etanol e/ou metanol, destinados ao acionamento de veículos automotivos, especialmente gasolina comum e óleo diesel, para melhorar sua tolerância para umidade e água dispersa e evitar separação de fase. Uma tal composição a ser aplicada a etanol e/ou metanol ou aos referidos combustíveis automotivos, compreende pelo menos dois, de preferência, três componentes escolhidos dentre as classes que compreendem; a) ácido graxo, saturado ou insaturado, com 12 a 20 átomos de carbono, ou suas misturas; b) aminas e poliaminas representadas pelo fórmula; H2 N{CH2)~ x~ CHR1CHR2}-NR3-(CHR4-CHR5 NH)~ y~R~ 6~(B) em que, R1, R2. R3, R4, R5e R 6, podem ser H ou CH3, individualmente, e x,y + 0, 1, 2, 3 ou 4, em que, no caso de x e y = o (zero) a fórmula passar a ser: H~ 2~N(CHR1- VHR2)-NR3- R6 (B') e no caso de x ser positivo e y - 0 a fórmula passa a ser H~2~N{N(CH2) ~ x~ CHR1 CHR2}NR3 R6; c) ésteres de polioxialquilenoglicóis, representados pelo fórmula: R1O(CHR~ 2~ - CHR3-0) ~ x~ R4, em que os radicais terminais R~ 1~e/oy R4podem ser estearila ou oleíla e x é um interiro na faixa de 2 a 35; e, eventualmente, 0 a 10%, no conjunto, de pelo menos um componente ulterior, escolhido dentre: d) componentes anfifilicos, compreendendo dietilenoglicol, dipropilenoglicol, álcool butílico normal, álcool butílico terciário, álcool octanóico, álcool dodecílico, uréia. e) substâncias ativadoras do índice de cetano, do grupo dos nitratos de alquila C3 a C10lineares ou ramificados, do grupo dos perácidos alifáticos e aromáticos e peróxido de hidrogênio. Pela formação de microemulsão da água nos combustíveis é possível adcionar até cerca de 25% de etano e/ou metanol, com um título de 95 a 99° G.L. à gasolina automotiva ou ao óleo diesel, com menor emiisãop de poluentes para a atmosfera."ADDITIVE COMPOSITION FOR LIQUID FUELS" The present invention relates to an additive composition for mixed liquid fuels, namely, containing ethanol and / or methanol, intended to drive automotive vehicles, especially common gasoline and diesel oil, to improve their tolerance for moisture and dispersed water and avoid phase separation. Such a composition to be applied to ethanol and / or methanol or to said automotive fuels, comprises at least two, preferably, three components chosen from the classes they comprise; a) fatty acid, saturated or unsaturated, with 12 to 20 carbon atoms, or mixtures thereof; b) amines and polyamines represented by the formula; H2 N (CH2) ~ x ~ CHR1CHR2} -NR3- (CHR4-CHR5 NH) ~ y ~ R ~ 6 ~ (B) where, R1, R2. R3, R4, R5 and R 6, can be H or CH3, individually, ex, y + 0, 1, 2, 3 or 4, where, in the case of x and y = o (zero) the formula becomes: H ~ 2 ~ N (CHR1- VHR2) -NR3- R6 (B ') and if x is positive and y - 0 the formula becomes H ~ 2 ~ N {N (CH2) ~ x ~ CHR1 CHR2} NR3 R6; c) polyoxyalkylene glycol esters, represented by the formula: R1O (CHR ~ 2 ~ - CHR3-0) ~ x ~ R4, in which the terminal radicals R ~ 1 ~ and / oy R4 can be stearyl or oleyl ex is an interier in the range of 2 to 35; and, eventually, 0 to 10%, together, of at least one further component, chosen from: d) amphiphilic components, comprising diethylene glycol, dipropylene glycol, normal butyl alcohol, tertiary butyl alcohol, octanoic alcohol, dodecyl alcohol, urea. e) cetane-activating substances, from the group of C3 to C10 linear or branched alkyl nitrates, from the group of aliphatic and aromatic peracids and hydrogen peroxide. By the formation of water microemulsion in fuels it is possible to add up to about 25% of ethane and / or methanol, with a 95 to 99 ° G.L.title to automotive gasoline or diesel oil, with less emission of pollutants into the atmosphere.
