Title (EN) PROCESS FOR MAKING PHENYLENE DIOXYDIACETIC ACID AND USE THEREOF
(FR) PROCÉDÉ DE FABRICATION D’ACIDE DIOXYDIACÉTIQUE DE PHÉNYLÈNE ET SON UTILISATION
Abstract:
(EN) A process for making phenylene dioxydiacetic acid comprises (a) contacting a dihydroxybenzene under reaction conditions with a salt of haloacetic acid in a solution without adding a haloacetic acid to produce a salt of phenylene dioxydiacetic acid; and (b) optionally converting the salt of phenylene dioxydiacetic acid to free phenylene dioxydiacetic acid. In some embodiments, 1,3-phenylene dioxydiacetic acid (RDOA) is made by reacting resorcinol with sodium chloroacetic acid in a reaction mixture with a pH in the range of about 7 to about 11 and at a temperature from about 70 °C to 105 °C. By adjusting the reactions conditions, a relatively high yield of 1,3-phenylene dioxydiacetic acid (i.e., greater than 80%) is obtained. The purified acid can be used in the synthesis of polyester, such as polyethylene terephthalate.
(FR) L’invention présente a trait à un procédé de fabrication d’acide dioxydiacétique de phénylène consistant à (a) mettre en contact un dihydroxybenzène dans des conditions de réaction avec un sel d'acide halogénoacétique dans une solution sans ajouter d’acide halogénoacétique afin de produire un sel d’acide dioxydiacétique de phénylène ; et (b) convertir éventuellement le sel d’acide dioxydiacétique de phénylène pour libérer l’acide dioxydiacétique de phénylène. Dans divers modes de réalisation, l’acide dioxydiacétique de 1,3-phénylène (RDOA) est fabriqué par réaction de résorcinol avec de l'acide chloracétique de sodium dans un mélange de réaction dont le pH est compris entre environ 7 et environ 11 et dont la température est comprise entre environ 70 °C et 105 °C. En ajustant les conditions de réactions, un rendement relativement élevé d’acide dioxydiacétique de 1,3-phénylène (c'est-à-dire supérieur à 80%) est obtenu. L'acide purifié peut être utilisé pour la synthèse du polyester, comme le polyéthylène téréphthalate.
