Kinetics of the Alkaline Hydrolysis of Nitrocellulose

Water Environment Research, 2001
Cellulose nitrate (nitrocellulose) is an explosive solid substance used in large quantities in various formulations of rocket and gun propellants. Safe destruction of nitrocellulose can be achieved by alkaline hydrolysis, which converts it to biodegradable products that can then be treated by conventional biological processes.

Degradation of nitrocellulose by fungi

Biodegradation, 2005
Three lignocellulolytic fungi, Trametes versicolor, Pleurotus ostreatus, and Coprinus cinereus, and two cellulolytic fungi Trichoderma reesei and Chaetomium elatum were tested for their ability to degrade nitrocellulose. They were provided with different carbon and nitrogen sources in liquid cultures.

Biodegradation of nitrocellulose

Journal of Energetic Materials, 1995
Abstract The research carried out in the past on the microbial degradation of nitrocellulose produced conflicting results primarily due to the lack of a proper analytical method for nitrocellulose estimation. Using an acetone extraction method, with appropriate corrections, Brodman and his coworkers concluded that certain fungal cultures are capable of

Mechanochemical effects in degradation of nitrocellulose and nitrocellulose–diphenylamine mixture

Thermochimica Acta, 2005
Abstract Dynamic mechanical analysis is combined with mass spectrometry to study nitrocellulose and nitrocellulose–diphenylamine films under oscillating strain. At a constant temperature (150–160 °C) and frequency 400–600 Hz nitrocellulose fractures demonstrating a modulus drop and release of products with m / z  = 30 and 44. At a linear heating (2 °

The Rheological Properties of Plasticized Nitrocellulose as a function of nitrocellulose precursor

Propellants, Explosives, Pyrotechnics, 1988
AbstractPropellant cords have been manufactured from nitrocellulose/nitroglycerin (50/50) pastes containing different types of nitrocellulose. The cords were manufactured using a solvent wet process involving incorporation and extrusion in the highly instrumented propellants processing facility at Waltham Abbey.

Temperature effects on the birefringence of nitrocellulose and nitrocellulose/nitroglycerine mixtures

Polymer, 1985
Abstract Changes in the optical path difference of nitrocellulose fibres of varying degrees of substitution over the temperature range −120°C to 130°C are interpreted as due to conformational changes in the primary nitrate group. Changes in path difference of nitrocellulose/nitroglycerine paste fibres over the same temperature range indicate an ...
