1,2-Benzenedimethanol Usage And Synthesis

Chemical Properties	white to light yellow powder
Uses	1,2-Benzenedimethanol is a raw material used in chemical synthesis.
Purification Methods	Recrystallise it from *C6H6, H2O, pet ether or pentane. It has been extracted in a Soxhlet with Et2O, evaporated and recrystallised from hot pet ether. It is also purified by dissolving in Et2O, allowing to evaporate till crystals are formed, filtering off and washing the colourless crystals with warm pet ether or pentane. The diacetate has m 35o, 35-36o. [Nystrom & Brown J Am Chem Soc 69 1197 1947, IR and UV: Entel et al. J Am Chem Soc 74 441 1952, Beilstein 6 IV 5953.]
