MS (EI, m/z): 296. 3. Results and discussion Acetalization of pentaerythritol (1 mmol) with benzal‐ dehyde (2 mmol) was selected as model reaction to optimize the reaction parameters namely, reaction tempera‐tures (60, 80, 90 and 100 C) and the amount of catalyst (1, 2, 3, 4 and 5 wt% of PE).	cache/eurjchem-1028.pdf	txt/eurjchem-1028.txt
