| | FUMARALDEHYDE BIS(DIMETHYL ACETAL) Usage And Synthesis |
| Chemical Properties | Clear colorless to slightly yellow liquid | | Uses | Fumaraldehyde bis(dimethyl acetal) may be used in the syntheses of C20-carotene and crocetin or descrocetin esters. It may be used in the preparation of fumaraldehyde dimethylacetal, (FDMA), by partial acid hydrolysis. | | Purification Methods | Dry it over fused CaCl2 and distil it in vacuo. The maleic (cis) isomer has b 112o/11mm, and d23 0.932 and n 251.4243. [Zeik & Heusner Chem Ber 90 1869 1957, Clauson-Kaas et al.
