Conclusions
-
1.
The conversions of 2,3-dihydropyran and 2-propyl-1,4-dioxene on Pt-C, active carbon, and quartz at 300 and 400° have been studied.
-
2.
At 300 and 400° dihydropyran is decomposed to acrolein with a yield of about 30%. Under similar conditions, propyldioxene undergoes cracking with the formation of gaseous products.
