Isomerization method |
| abstract |
PROBLEM TO BE SOLVED: To obtain as much as possible the corresponding all-E-isomer starting from an isomer of a vitamin A compound or a mixture of arbitrary isomers, and to obtain the all-E-isomer The present invention provides a simple and inexpensive method for isolating the isomer, and the 13-Z-isomer coexisting in equilibrium with this isomer, in the purest possible form. SOLUTION: The Z isomer of a vitamin A compound or some mixture of such isomers isomerized using nitric oxide or a gaseous mixture containing nitric oxide as a catalyst to form all-E-isomer. To obtain the isomer and 13-Z-isomer. |
