Title
(EN) ESTERS OF SECONDARY HYDROXY FATTY ACID OLIGOMERS AND PREPARATION THEREOF
(FR) ESTERS D'OLIGOMÈRES D'ACIDES GRAS À HYDROXY SECONDAIRE ET LEUR PRÉPARATION
Abstract
(EN)
Prepare an ester of a secondary hydroxy fatty acid oligomer by first partially homopolymerizing a hydroxylated fatty acid compound, reacting the partially homopolymerized hydroxylated fatty acid compound with an alcohol to form an intermediate product, and capping the intermediate product with an acid, acid anhydride or ester. The ester of a secondary hydroxy fatty acid oligomer may be represented as follows: (3) where R is an alkyl group that contains from six to twelve carbon atoms, R1 is hydrogen or a methyl radical, x is an integer within a range of from 8 to 12, n is an integer between 1 and 20, R2 is an alkyl group that contains from one carbon atom to twenty carbon atoms and R3 is an alkyl group that contains from one carbon atom to twelve carbon atoms.
(FR)
L'invention porte sur un procédé de préparation d'un ester d'un oligomère d'acides gras hydroxy secondaire par les opérations consistant à : tout d'abord conduire une homopolymérisation partielle d'un composé acide gras hydroxylé, à faire réagir le composé acide gras hydroxylé partiellement homopolymérisé avec un alcool pour former un produit intermédiaire, et à conduire un coiffage du produit intermédiaire par un acide, un anhydride d'acide ou un ester. L'ester d'un oligomère d'acide gras à hydroxy secondaire peut être représenté comme suit : où R est un groupe alkyle qui contient de six à douze atomes de carbone, R1 représente hydrogène ou un radical méthyle, x est un entier se situant dans la plage de 8 à 12, n est un entier entre 1 et 20, R2 est un groupe alkyle qui contient d'un atome de carbone à vingt atomes de carbone, et R3 est un groupe alkyle qui contient d'un atome de carbone à douze atomes de carbone.
