Abstract : methanesulfonic acid method was used to prepare five acylated chitins. except heptanoyl chitin, four of them, i. e. acetyl chitin, propionyl chitin, butyryl chitin and hexanoyl chitin, had high degree of substitution ( from 1. 5 to 2. 0 ) and exhibited lyotropic liquid crystalline behavior and cholesteric phase. as the length of the side chain increased the critical concentration ( w / w ) somewhat increased from 0. 21 to 0. 26 because the chain rigidity dropped. the critical concentration values of all the four derivatives were much higher than that of chitin ( 0. 12 ) due to the decrease of intramolecular hydrogen bonds. the four acylated chitin can form typical banded texture after being sheared. there minimum concentrations to form banded texture of them were evidently different, varied from 0. 25 ( for acetyl chitin ) to 0. 37 ( for hexanoyl chitin ). these results further indicated that liquid crystallinity decreased while the length of flexible side substituents increased
文摘:四種羧酰化甲殼素即乙酰化、丙酰化、丁酰化和己酰化甲殼素在二氯乙酸溶液中均呈現膽甾型溶致液晶相.臨界濃度隨側基長度增加而略有增加，衍生物的臨界濃度明顯都比原甲殼素高許多，這些規律都可以用鏈剛性的變化來解釋.四種羧酰化甲殼素在剪切時均能形成條帶織構，而且能形成條帶織構的最低濃度有明顯差別，隨側基長度增加而提高，進一步表明側基較長，液晶性減少Analysis f k and na in nepheline were curried out with higher precision and repeatability by means of adding fluohydric acid during sample melting to remove sio2, adjusting the ratio of k and na in the solution to reduce the mutual interference of the two elements, and adding cesium chloride to eliminate ionization interference
摘要本方法用於測定霞石中的鉀、鈉，主要通過在溶樣時加入氫氟酸除去二氧化矽，調整溶液中鉀、鈉的含量，消除互相之間的干擾，加入氯化銫消除電離因素的干擾，提高了分析結果的準確性和重現性，使測定結果更接近化學分析值。Analysis of k and na in nepheline were curried out with higher precision and repeatability by means of adding fluohydric acid during sample melting to remove sio2, adjusting the ratio of k and na in the solution to reduce the mutual interference of the two elements, and adding cesium chloride to eliminate ionization interference
