Abstract
Inventia se refera la un procedeu de preparare a 2-(4-izobutilfenil)-propionaldehidei fara izolarea intermediarilor conform caruia masa de reactie continand esterul etilic al acidului 2-(4-izobutilfenil)-2,3 expoxibutiric se trateaza cu o solutie apoasa de hidroxid de sodiu la 60....80 degree C, dupa care amestecul de reactie se aciduleaza la pH 3....5 si se agita la temperatura camerei 1....2 h, 2-(4-izobutilfenil)-propionaldehida bruta obtinuta se spala cu apa la pH neutru, dupa care se supune unui proces de antrenare cu vapori de apa.
