| 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. |

| 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. |

| 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. |
