| | FEMA 2129 Usage And Synthesis |
| Occurrence | Has apparently not been reported to occur in nature | | Preparation | The α, α?- and α, β-isomers are obtained in mixture by heating glycerol and benzaldehyde to 145 to 170°C under a stream
of CO2; the isomers are subsequently isolated, exploiting the solubility differences; the α, α?-isomer is readily converted to the α,
β-form by heating in the presence of HCl. |
