実験手順
Described herein is a process for the preparation of 9 (2-hydroxyethyl)-7, 11-dioxaspiro (5,5) undecane by reacting Cis-but-2-2ene-1,4 diol with cyclohexanone in the presence of a heterogeneous sulphonated nitro coal acid catalyst to obtain 7, 12-dioxaspiro (5,6) dodec-9-ene which is reacted with syngas in the presence of a catalyst, namely RhH (CO) (TPP)3, to obtain 9-formyl-7, 12-dioxaspiro (5,6) dodecane which is reduced and the reduced product is rearranged to yield 9-(2-hydroxyethyl)-7,11-dioxaspiro [5,5] undecane.
