Pyran is a six-membered heterocyclic ring with two double bonds and one oxygen atom. It has two isomers, 2 H -pyran and 4 H -pyran, and many derivatives are important biological molecules.
Pyran's proprietary technology represents the only cost-effective gateway to produce five-carbon (C5) products feasibly on purpose. Pyran uses agricultural products to make 100% Biobased 1,5-Pentanediol while significantly reducing greenhouse gas emissions compared to petroleum-based chemicals currently on the market such as 1,6-Hexanediol and 1,4-Butanediol.
pyran, any of a class of organic compounds of the heterocyclic series in which five carbon atoms and one oxygen atom are present in a ring structure. Of two possible simple pyran compounds, only one is known; it was prepared in 1962 and found to be very unstable. Among the stable members of this family is tetrahydropyran, made by hydrogenating the dihydro compound. Sugars often occur in ...
