β-Carotene was heated at 210 °C for 4 h, and the thermal degradation products were separated by liquid column and thin-layer chromatography. Two compounds were tentatively identified as 3,7,10-tri-methyl-1-1,12-bis(2,6,6-trimethylcyclohex-1-enyl)dodeca-1,3,5,7,9,11-hexaene and 3,6-dimethyl-1,8-bis(2,6,6-trimethylcyclohex-1-enyl)octa-1,3,5,7-tetraene. A mechanism for their formation is proposed.
