Verfahren zur Herstellung von 3,4-Dihydro-2H-pyran

摘要

The invention relates to a method for producing 3,4-dihydro-2H-pyran by reacting tetrahydrofurfuryl alcohol on solid oxidic catalysts at temperatures ranging from 150 to 400 DEG C and at pressures ranging from 0.001 to 50 bar. The inventive method is characterized in that the reaction is carried out in the gas phase inside a multi-tube reactor.
