Abstract
Inventia se refera la un procedeu de obtinere a fenilmalonatului de dietil si consta în aceea ca peste amestecul de fenilacetat de etil si carbonat de etil se adauga sodiu metalic, se încalzeste amestecul de reactie la 100...105 degree C, se neutralizeaza cu acid clorhidric, se separa straturile formate, se distileaza stratul organic, din care se recupereaza carbonatul de etil care se recircula, reziduul fiind supus unei distilari fractionate în vid.
