Abstract

The effect of variations in the reaction conditions on the composition of the end product was studied in the reaction of styrene with formaldehyde in acetic acid. Initially a relatively large amount of 4‐phenyl‐1,3‐dioxan is formed along with telomer homologues. This cyclic formal is cleaved by protolysis in a comparatively slow secondary reaction with styrene; it thus acts as an intermediate formaldehyde donor.

The results are interpreted in terms of a carbonium‐ion mechanism.

Acetic acid thionyl chloride reaction was studied in chloro-, bromo-and nitrobenzene. The reaction seems to follow simple course in the beginning, but after some time complications occur. The percentage of hydrogen chloride in the effluent gases was determined by dissolving the gases in water and me
