Abstract: | β-Carotene was heated with a clay mineral (kaolinite) under vacuum at temperatures ranging from 200 to 350°C for 24 h. Several polymethylbenzenes, naphthalenes and probably phenanthrenes were observed in the pyrolysate at 350°C. Furthermore, ionene, some polymethylbenzenes and a dimethylnaphthalene were detected at temperatures between 200 and 250°C. It was concluded that the clay mineral may act as an acidic catalyst. |
