hydrogenolysis. Acetalisation, with the corresponding aldehyde, gave rise to 69% to 91% isolated yields of erythritol acetals, and 63% to 79% yields of pentaerythritol acetals. Hydrogenolysis of these acetals was performed resulting in good yields of erythritol (72% to 86%) and pentaerythritol (78% to 83%) derivatives. The physico-chemical analysis of these ethers was realized using DSC and TGA analysis
