Abstract
Inventia de fata se refera la un procedeu de preparare simultana a acidului p-toluic si amonoesterului acidului tereftalic prin oxidarea xilenului sau a esterilor acidului toluic cu oxigen, conform caruia lichidul din reactor este reintrodus cu adaos de gaze continând oxigen prini ntermediul unor ajutaje în stare pulverizata în reactor, raportul în volume gaz/lichid este de 1 ... 20 si diferenta de la presiunea din reactor este de 0,1 ... 3 bari, în punctul de amestec gaz/lichid sementine viteza de masa de 1500 ... 6000 kg/sec m patrat, si la o instalatie constituita dintr-o statie de pompare legata de un schimbator de caldura si un reactor care este prevazut cu unul sau mai multe ajutaje dispuse sub nivelul de lichid care prezinta orificii de evacuare.
