ABSTRACT

In a subsequent RJRT research effort in 1963 and 1964, several anhydrides (see Table VII-1) were isolated from tobacco smoke and identified by Fredrickson (1233, 1235) during his study of the composition of burley tobacco smoke condensate. Two decades later, several additional anhydrides (see Table VII-1) were identified as components of Oriental tobacco by Schumacher (3543).
