HIGHLIGHTS
- who: Experimental and collaborators from the SchoolHuangshi, People's Republic of China have published the paper: A polymorph of terephthalaldehyde, in the Journal: (JOURNAL) of 15/07/2008
SUMMARY
A new orthorhombic polymorph of terephthalaldehyde, C8H6O2, with a melting point of 372 K, has been obtained by recrystallization from ethanol. At room temperature, the crystals transform into the well known monoclinic form, with a melting point of 389 K. The crystal_structure of the monoclinic form involves C-H O hydrogen_bonds, but no such bonds are observed in the orthorhombic form. Related literature For . . .
