Steps:

1.3; 2.3; 3.3; 4.3; 5.3; 6.2

3) Add 1.81g of solid catalyst (supporting rhodium chloride) to the obtained organic phase containing cis-trans β-carotene, stir and react at 50°C for 20.0h, and then filter and recover the solid catalyst. The filtrate is lower than 45°C to recover the solvent. A red viscous solid is obtained, 500 ml of methanol is added, the reflux operation is 20 minutes, and the weight after vacuum drying is 18.1 g, of which the all-trans content accounts for 98.5%
