与acetyl cellulose相关的网络例句 [注：此内容来源于网络，仅供参考]

Insects polysaccharide from insect crust are a natural macromolecular polymers that remove behind the acetyl group getting usually that paries draw, which are currently found only bring positive charge of the animals cellulose in the natural world- containing amino polysaccharide of high-molecular compound.

昆虫多糖是从昆虫体壁提取的甲壳素脱去乙酰基后得到的一种天然高分子聚合物，也是目前发现的自然界中唯一带正电荷的可食性动物纤维素——含氨基多糖的高分子化合物。

In this paper the study on optimizing the esterification of cellulose and some character of CAB(the degree of substitution of cellulose, solubility, the thermal properties and molecular weight) was discussed. The mechanism of the esterification of cellulose in butyric acid/ acetic acid/ butyric anhydride which comprises the creation of the acetic butyric anhydride, acetyl cation and butyryl cation was investigated by the study of the effect of the content of the organic acid and anhydride on the degree of acetyl and butyryl substitution of cellulose.

最后本文根据纤维素在丁酸/乙酸/丁酸酐中的酯化反应中有机酸以及酸酐的添加量对最后产物纤维素醋酸丁酸酯中乙酯或者丁酯取代度的影响，提出纤维素在丁酸/乙酸/丁酸酐中的酯化反应经历一个混和酸酐以及乙酰碳正离子、丁酰碳正离子的生成过程。

Cellulose acetate butyrate with high or low degree of butyryl substitution was synthesized in heterogeneous system(butyric acid/ acetic acid/ butyric anhydride/ sulfuric acid) using the "free solvent" method. The effect of activation time, esterification time, the molecular weight of cellulose and the content of the organic acid or anhydride on the degree of acetyl and butyryl substitution of cellulose was discussed.

在非均相体系中进行酯化反应，采用&反应性溶剂&，以硫酸作为催化剂合成出从高丁酯含量到低丁酯含量的纤维素醋酸丁酸酯，研究有机酸以及酸酐的添加量、活化时间、酯化反应时间以及原料纤维素的分子量对酯化产物纤维素醋酸丁酸酯的影响。
