How will understanding of attitudes and predisposition enhance teaching? In this study, FT-IR, 13C-NMR, 1H-NMR and electric conductivity were used to measure changes of crystalline structure and formation of chitin-solvent complex. Comparison of methods for determining the deliquescence points of single crystalline ingredients and blends. Xiaoqin WU, Shitang TONG, Baohong GUAN, Zhongbiao WU. A kinetic study. Tomazic BB, Nancollas GH. We have found that calcium chloride dihydrate saturated methanol is a mild and efficient solvent system for chitin, probably because rigid crystalline structure of chitin is destroyed by calcium ion.
