Abstract
Inventia se refera la un procedeu pentru prepararea de derivati de glioxal cu formula generala I: în care R reprezinta hidrogen sau un radical de alchil inferior, A reprezinta radicalul în care R1 reprezinta un radical de alchil inferior cu lant drept sau ramificat, prin ozonizarea unui acetal alfa, beta nesaturat, urmata de hidrogenarea catalitica a produsului de ozonizare, la care un dialchilaoctal al acroleinei cu formula generala II: în care R si R1 au semnificatiile de mai sus, se dizolva într-un solvent, se supun ozonizarii la o temperatura de -50 degree C pana la 0 degree C cu o cantitate echivalenta de ozon si apoi solutia obtinuta se supune hidrogenarii continue într-i suspensie de catalizator de platina sau paladiu, mentinand un continut de peroxid de maximum 0,1 mol/l, la o valoare a pH-ului de 2 pîna la 7 si la o temperatura de 15 pana la 45 degree C.
