Quality Control of Tin(II) oxalate. The reaction of aromatic heterocyclic molecules with protons is called protonation. Aromatic heterocycles are more basic than benzene due to the participation of heteroatoms. Compound: Tin(II) oxalate, is researched, Molecular C2O4Sn, CAS is 814-94-8, about Preparation and study of morphology of mesoporous anodic films grown on tin foil. Author is Vasilieva, T. A.; Uvarov, N. F.; Bokhonov, B. B..
Mesoporous anodic layers were obtained on high-purity tin foils in electrolyte of two types: 0.3 M oxalic acid and 1 M NaOH in various anodizing modes. It was demonstrated that in both cases at low voltages below 4 V barrier films form. In acidic electrolyte the formation of tin (II) oxalate was observed whereas in basic electrolytes SnO2·nH2O seems to be formed. At intermediate voltage values from 4 to 8 V mesoporous films may be obtained with average size of pores of 20-40 nm, mesopores are rather uniformly distributed along the surface. It was found that in contrast to alumina anode films no linear dependency between pore diameter and voltage was observed at anodizing of tin foil. At voltages above 8 V and/or long-term anodization the film cracks and the film split to sep. islands.
Different reactions of this compound(Tin(II) oxalate)Quality Control of Tin(II) oxalate require different conditions, so the reaction conditions are very important.
