Autor: E. G. Ivanova, Anatolii I. Usov, Z. I. Kuznetsova
Publikováno v: Bulletin of the Academy of Sciences of the USSR Division of Chemical Science. 22:1798-1801
The condensation of cellulose dialdehyde with nitromethane proceeds in two directions; in harmony with this, two kinds of amino polyacetals can be obtained when the condensation products are reduced.
