Summary
-
1.
Chemical changes in the structure of cotton cellulose due to oxidation with sodium hypochlorite at different pH have been investigated by means of specific quantitative micromethods.
-
2.
The following groups have been found in the oxycellulose obtained by hypochlorite oxidation: uronic and non-uronic carboxylic groups, C8 aldehydic groups,α-hydroketonic and lactone groups, and carbonic acid ester (ether) groupings.
-
3.
The oxycelluloses obtained by oxidation in acid and neutral solution have a similar structure, different from that obtained in alkaline solution.
-
4.
A reaction mechanism is advanced for the oxidative degradation of cellulose by action of sodium hypochlorite at various pH. This mechanism satisfactorily explains the chemical behaviour of the oxidation products.
-
5.
The various oxidative processes shown to occur may be utilized for the better control of such processes, and for the preparation of cellulose oxidation products of known properties.
