Abstract
Inventia se refera la prepararea esterilor de acizi grasi prin reactia olefinelor si a monoxidului de carbon în prezenta unui catalizator cu continut de cobalt si a unui promotor constînd din piridina si/sau alchilpiridine nesubstituite în pozitia orto, tratînd amestecul de reactie cu un gaz cu continut de oxigen, dupa care amestecul de reactie se separa, în doua trepte de distilare, peima treapta lucrînd la o presiune mai ridicata decît treapta a doua, rezultînd un distilat lipsit de cobalt si la treapta a 2-a de reziduu de distilare un concentrat continînd întreaga cantitate de cobalt folosita, apoi concentratul este reluat în piridina si/sau alchilpiridina nesubstituita în pozitia orto, suspensia astfel obtinuta se trateaza cu si hidrogen la o temperatura cuprinsa între 100 si 250 degree C si la o presiune cuprinsa între 50 si 400 bari, si produsul obtinut dupa tratare se recicleaza la sinteza esterului de acid gras.
