Procedure

A similar experiment to that of example 1 is carried out using this time 2 kg of crude product comprising 42% by weight of glycerol, 14% by weight of water and a large amount of volatile products (methanol, ethanol). The acetone is used in the same molar ratio as is for example 1 and the 2,2-dimethyl-1,3-dioxolane-4-methanol obtained has a purity of 98%.
