The Controlled Thermal Decomposition of Cellulose Nitrate. Vii. Carbonyl Compounds

摘要

An investigation of the carbonyl compounds formed from the ignition of cellulose nitrate was made. Isolated as the 2,4-dinitrophenylhydrazine derivatives were acetone, acetaldehyde, formaldehyde, methylglyoxal, glyoxal, mesoxaldehyde and hydroxypyruvaldehyde. A gas chromatographic study of the cellulose nitrate (cast from ethyl acetate) ignition products demonstrated the presence therein of acetaldehyde, acetone, acrolein, ethyl acetate, hydrogen cyanide and a now, unidentified substance which is not a carbonyl compound. Ethanol is not a product of ignition of cellulose nitrate. The origin of the compoundss isolated is discussed. (Author)
