| description | The invention relates to a method for producing biolubricant from vegetable oil, comprising the steps of (a) esterification reaction of the product of hydrolysis of the vegetable oil using a branched aliphatic alcohol; (b) epoxidation reaction of the esters produced in step (a); and (c) nucleophilic substitution reaction of the epoxidised esters produced in step (b) using a branched aliphatic alcohol. The invention also relates to a biolubricant produced by this method. More specifically, the invention relates to a biolubricant produced from a ricinoleic fatty acid, the formula of which is represented in figure 1 of the present invention, where R1 is a hydroxyl, or of formula R3COO-, R3 being a C1-C3 alkyl radical, preferably a methyl radical; and R2 consists of a main C4-C8 hydrocarbon chain and a branched C1-C3 hydrocarbon chain.
La présente invention concerne un procédé d'obtention de biolubrifiant à partir d'huile végétale, comprenant les étapes suivantes : (a) réaction d'estérification du produit d'hydrolyse de l'huile végétale au moyen d'un alcool aliphatique ramifiée ; (b) réaction d'époxydation des esters obtenus dans l'étape (a); et (c) réaction de substitution nucléophile des esters époxydés obtenus dans l'étape (b) au moyen d'un alcool aliphatique ramifié. La présente invention concerne également un biolubrifiant obtenu au moyen de ce procédé. Plus particulièrement, l'invention concerne un biolubrifiant produit à partir d'un acide gras ricinoléique, dont la formule est illustrée dans la figure 1 de la présente invention, et où R1 est hydroxyle ou de formule R3COO-, R3 étant un radical alkyle C1-C3, de préférence un radical méthyle, et R2 consiste en une chaîne principale d'hydrocarbures C4-C8 et une chaîne ramifiée d'hydrocarbures C1-C3.
A presente invenção descreve um processo de obtenção de biolubrificante a partir de óleo vegetal que compreende as etapas de (a) reação de esterificação do produto de hidrólise do óleo vegetal utilizando um álcool alifático ramificado; (b) reação de epoxidação dos ésteres obtidos na etapa (a); e (c) reação de substituição nucleofílica dos ésteres epoxidados obtidos na etapa (b) utilizando um álcool alifático ramificado. Além disso, a presente invenção também descreve um biolubrificante obtido a partir do processo. Mais especificamente, é descrito um biolubrificante produzido a partir de um ácido graxo ricinoleico, cuja fórmula encontra-se ilustrada na Figura1 da presente invenção, e onde R1 é uma hidroxila ou da |
