2,5-Furandimethanol → 2,5-Tetrahydrofurandimethanol

Temperatur

30 °C

Into a 300 ml stainless steel autoclave was charged 40.03 g. 2,5-bis-(hydroxymethyl)furan, 100 ml methanol and 3 g. of cationic ruthenium zeolite. After pressurizing with H2 to 1900 psig and initiating stirring, the exothermic reduction occurred increasing the temperature from 30° C. (reaction temperature) to 61° C. The reduction temperature started to decrease as the reduction slowed down. The reduction was complete in 30 minutes and workup gave 99 percent 2,5-bis-hydroxymethyl tetrahydrofuran as the sole product (verified by analysis).
