Process for the production of Acrylic acid from acrolein by redox reaction and use of Solid oxidosmixtos composition as redox System in this reaction.
Use the solid composition of mixed oxide in the formula: Mo (12) V (a) Sr (b) w (c) Cu (d) Si (E) or (x),where a has values between 2 and 4; b between 0.1 and 6; c between 0 and 12; d between 0 and 6, and between 0 and 15; x is the amount of oxygen bound to the other elements and that depends on oxidation conditions, in the manufacture of acrylic acid by oxidation of acrolein, said solid composition reacting with acrolein according to the redox reaction: SOLID (oxide) + ACROLEIN- - SOLID (reduced) + ACRYLIC ACID. In order to make the acrylic acid, a gaseous mixture of deacrolein and water vapor and possibly an inert gas is passed over a solid composition of the aforementioned formula,para llevar a cabo la reacción redox operando a una temperatura de 200 a 500 C bajo una presi n de 1 01 x 10000 a 1 01 x 1000000 Pa (0 1 a 10 atm sferas)And there's a 0.01-90 second break without molecular oxygen
