Edible Membrane Studies on Deacetyl Konjac Glucomannan;
脱乙酰基魔芋葡甘聚糖可食性膜材料研究
Deacetyl Modification of Konjac Glucomannan(KGM) by alkali and the effects of different times of alkali treatment on mechanical properties and nanometer-scale micromorphological features of membranes from KGM were explored.
研究了天然高分子魔芋葡甘露聚糖加碱去乙酰基改性,考察了不同碱处理时间对魔芋葡甘聚糖(KGM)膜力学性能及纳米尺度微观形貌特征的影响,单因素方差分析表明,不同碱处理时间对KGM膜力学性能与膜面AFM形貌图像三维粗糙度数字化参数——均方根粗糙度(RM S)、平均面粗糙度(R a)、最大高低差(P-V)、表面积(S)、表面积率(S ra tio)、10点平均粗糙度(R z)等的影响并不相同,其中,对KGM膜耐折度(FE)与RM S、R a、R z参数具有显著影响(P<0。
Based on the method of Lemieux, this paper applies a carbohydrate compounds synthesis method to phenol compounds synthesis, and reports for the first time a convenient and efficient procedure developed for conversion of phenol protective group from acetyl to benzyl with BnBr and KOH in refluxing THF in one-pot.
在Lemieux方法的基础上,将应用于糖类化合物的方法首次应用到酚类化合物上,报道了乙酰基保护的酚类化合物,在苄溴、氢氧化钾作用下于四氢呋喃中回流通过一锅转化法转换得到苄基保护化合物;在有多个乙酰基同时存在条件下,通过调节氢氧化钾的用量来控制苄基取代的程度。
