Patent

CA 2414731

The invention relates to a method for producing blends of phthalic acid diesters, decanols and tridecanols, according to which phthalic acid or a reactive derivative thereof is reacted with a mixture of at least one decanol and at least one tridecanol. The invention also relates to blends obtained as above, to their use as plasticizers for moulding compounds and to mixtures of isomeric tridecanols that are suitable for producing said blends.

La présente invention concerne un procédé permettant la préparation de mélanges de diesters de l'acide phtalique avec des décanols et des tridécanols, dans lequel de l'acide phtalique, ou un dérivé réactif dudit acide phtalique, est converti avec un mélange constitué d'au moins un décanol et d'au moins un tridécanol. Cette invention concerne également les mélanges ainsi obtenus, leur utilisation en tant que plastifiants dans des matières à mouler, ainsi que des mélanges de tridécanols isomériques permettant leur préparation.
