WebAs shown in Table 5.6.1, even at relatively high temperatures, the parent vanillin PG acetal is still present in the pyrolysate. The stability of this acetal is caused by the stability of the 1,3-dioxolan cycle formed in reaction (5.6.2). Other fragments are formed from the cleavage of a different bond in the acetal molecule. http://chemweb.bham.ac.uk/coxlr/Teaching/1st_Year/Carbonyl_Group/Carbonyl_pdfs/lecture%209%20(student%20HO).pdf
