Abstract To get the proper treatment conditions, sulfonation reactions of persimmon
tannin with sodium sulfite and sulfuric acid were proceeded in various settings, respectively.
Also, the property changes were investigated by carrying out the additional analysis:
elementary analysis and instrumental analysis using FT-IR, DSC, and TGA. The degree
of -SO3Na substitutions appeared 0.216 and 0.208 under the treatment time of 3 hours
and 6 hours, respectively and the degree of -SO3H substitutions indicated 0.200 and 0.167
under 9 hours and 18 hours, respectively by elemental analysis. In terms of the FT-IR
spectras, there was a peak based on the bonds of pyran ring and ether in relation to nontreated
and sulphonated tannin at 1,102cm-1. No peak was shown in the sulfited tannin.
An absorption peak which was due to the C→O of secondary -OH group became evident
in nontreated and sulfited tannin at 1,092cm-1 and 1,090cm-1, respectively but the same
result was not found in sulphonated tannin. The results of TGA analysis of the sulfonated
persimmon tannin showed that the sulfonation of it improved thermal properties. |
