Sorry, no etymologies found.
With regard to denitration which is both a delicate and disagreeable operation: none of the agents recommended to substitute the sulphydrates have proved available.
Several processes have been used for the denitration of these acids.
The acids themselves may either be run to waste, or better treated by some denitration plant.
When this has been separated by displacement, the acids are ready for denitration, or can be safely stored without further precaution.
After drying, denitration, and washing, it may be spun and dyed like natural silk.
He also considers that the bisulphide of carbon, which must be regarded as a noxious compound, is a serious bar to the industrial use of the process, and for economic work he considers that the regeneration of ammonia from the precipitating liquors is necessary and would be as objectionable as the denitration baths in the collodion process.
It must be noted that according to the concentration of the solution and variations in the process of denitration the constants for the yarn are subject to very considerable variation.
In Table I will be found some important constants for the nitrocellulose fibre; also the fibre after denitration and the comparative constants for natural silk.
The product in denitration had therefore reverted completely to a cellulose (hydrate), no oxy-derivative being present.
It is well known that the denitration is nearly complete, traces only of nitric groups surviving.
