Alpha pinene, structure

H. van Bekkum et al. (17) reported that the alpha-pinene oxide 9 can be succesfully converted to campholenic aldehyde 10 (Eq. 15.2.5) in the presence of a BEA-zeolite. Ti-BEA proves to be an excellent catalyst for the rearrangement of a-pinene oxide to campholenic aldehyde in both the liquid and vapor phase. This is mainly attributed to the presence of isolated, well-dispersed titanium sites in a Bronsted-acid-free silica matrix. Furthermore, the unique molecularsized pore structure of the zeolite may enhance selectivity by shape-selectivity. [Pg.309]

Dipentene is described as a product of fractionation of pine oils containing related monocyclic terpene hydrocarbons, predominantly dipentene. (Structurally, dipentene is the Same as lim-onene. D-limonene is one of the 2 optical isomers of dipentene.) Other components of commercial dipentene include carene and alpha- and beta- pinene. [Pg.166]
