在羧甲基化反应过程中，碱化甲壳素分散在溶有氯乙酸的异丙醇中，氯乙酸缓慢的渗入碱化甲壳素颗粒中，先与碱化甲壳素颗粒的外表层发生反应然后再与内层的碱化甲壳素反应 碱化甲壳素：alkali chitin 羧甲基化：Carboxymethylation 氯乙酸：chloroacetic acid 异丙醇：isopropanol |

| During the process of carboxymethylation, alkali chitin is dispersed in the isopropanol solution with the dissolved chloroacetic acid. The chloroacetic acid permeating into alkali chitin particle reacts with its outer layer first, and then with the inside alkali chitin. |

| during a carboxymethylation process, alkali chitin is dispersed in the isopropanol solution of chloroacetic acid. The chloroacetic acid slowly immigrates into alkali chitin particle and reacts first with its outer layer and then with the alkali chitin of its inner layer. |

| When carboxymethylation reaction takes place, alkali chitin will disperse in isopropanol with chloroacetic acid. Chloroacetic acid will permeate slowly into the particles of alkali chitin or react with the outer layer of alkali chitin and then with the inner. |
