Abstract
L'invention concerne un procédé de production d'acide p-toluique et de ses dérivés comprenant une étape a) de réaction de Diels-Alder entre l'acide sorbique et/ou ses dérivés, et l'éthylène pour obtenir l'acide 4-méthylcyclohex-2-ène-oïque et/ou ses dérivés correspondants, en présence ou non d'un catalyseur et en présence ou non d'un solvant, ladite étape a) opérant à une température comprise entre 0°C et 400°C et à une pression comprise entre 0,1 et 20 MPa, une étape b) d'aromatisation de l'acide 4-méthylcyclohex-2-ène-oïque et/ou de ses dérivés correspondants obtenus à l'issue de l'étape a) pour former l'acide p-toluique et/ou ses dérivés, en présence d'un ou plusieurs catalyseurs et en présence ou non d'un agent oxydant, ladite étape b) opérant à une température comprise entre 50°C et 400°C et à une pression comprise entre 0,1 et 20 MPa. L'acide p-toluique ou ses dérivés ainsi obtenus peut ensuite avantageusement être converti en p-xylène qui peut être oxydé en acide térephtalique. L'acide p-toluique ou ses dérivés peut également être converti en acide térephtalique.
