oxalic acid

详情

Molecular formular: C2H2O4
Molecular weight: *0.*3
Nature: General oxalate crystallization of water containing two elements, is a colorless crystal
transparency, its crystal structure has two forms, that is, α-(diamond) and β-(monoclinic Crystal), the melting point, respectively, α-type: **9.5 ?c, β type: **2 ?c. The relative density, α-type: 1.**0, β type: 1.**5. Refractive index of 1.**0. Oxalate in the distillation of **0 ?c began, **5?c at the rapid sublimation, **7 ?c at the large number of sublimation and started to decompose. Soluble in ethanol, dissolve in
water, ethylether-soluble, insoluble benzene and chloroform.
