Abstract

Inventia se refera la un procedeu de preparare a metacrolinei si a acidului metacrilic prin oxidarea în faza de vapori a aldehidei izobutilice cu oxigen molecular sau cu un gaz continînd oxigen molecular în prezenta unui catalizator. Oxidarea aldehidei izobutilice are loc la temperaturi cuprinseîntre 250 si 400 degree C, în prezenta unui catalizator format în principal din compusi oxigenati de molibden vanadiu si fosfor si unul sau mai multe elemente activatoare alese dintre cupru, zinc, toriu aluminiu si fosforsi unul sau mai multe elemente activatoare alese dintre cupru, zinc, toriu, aluminiu, germaniu, nichel, fier, cobalt, zinc, titan, plumb, reniu, zirconiu, ceriu, crom bismut arsen, potasiu, rubidiu, cesiu si taliu în astfel de proportii încît sa corespunda formulei empirice:(vezi form. in desc.) în care ''x''reprezinta unul sau mai multe elemente alese dintre:potasiu, rubidiu, cesiu si taliu, iar coeficientii a,b,c,d,e si f reprezinta numarul de atomi ai elementelor care intra în constitutia amestecului catalitic si sunt egali cu a=10, b=0,5...6 de preferinta cuprinde 0,5 si 3, c =0,5.....6 de preferinta 0,5....3, d =0,01.....0,8 de preferinta 0.....0,5 f are valoarea necesara satisfacerii valentelor celorlalte elemente.
