Centrifuging has been used extensively in chemical industries, including the manuf of expls. For example in the DuPont method of manuf of NC(See this vol of Encyclopedia, under Cellulose, Nitro Manufacture), the sepn of NC from the spent nitrating acid is done by centrifuging. Another example is the sepn of TNT crysts from "sellite soln(Na2S03 in water) and then from wash water, which will be described under Toluene, Trinitro Manufacture. It can be done by centrifugation or by vacuum. filtration using a "Nutsch ... [Pg.537]

Gun-cotton is also dissolved in acetone or acetic ether until it has taken the form of a jelly. It is then rolled into thin sheets, and when dry cut up into little squares. In the manufacture of smokeless powders from nitro-cellulose, nitro-lignine, c., the various substances are mixed with the gun-cotton or collodion-cotton before granulating. [Pg.37]

Ethers and alcohol ethers Ethers such as ethyl ether are excellent solvents for some of the natural resins, oils, and fats. The usual forms of ether used in protective coatings are alcohol ethers such as ethylene glycol mono methyl ether, known commonly as cellosolve. Cellosolve is a good solvent for many oils, gums, natural resins, and synthetic resins such as alkyds, ethyl-cellulose, nitro-cellulose, polyvinyl acetate, pol)Tvinyl butyryl, and phenolics. Cellosolve is a slow solvent that is used in many lacquers to improve flow-out and gloss. [Pg.614]

Other. 2-Nitro-1-butanol is an excellent solvent for many polyamide resins, cellulose acetate butyrate, and ethylceUulose. It can be utilized in paint removers for epoxy-based coatings. 2-Hydroxymethyl-2-nitro-l,3-propanediol is usebil for control of odors in chemical toilets. Its slow release of formaldehyde ensures prolonged action to control odor, and there is no reodorant problem which sometimes is associated with the use of free formaldehyde. 2-Hydroxymethyl-2-nitro-l,3-propanediol solutions are effective preservative and embalming fluids. The slow Uberation of formaldehyde permits thorough penetration of the tissues before hardening. [Pg.62]

Nitro-filter cloths are composed of cellulose nitrate, which is an ester of cellulose. Any chemical compound that will saponify the ester will destroy the cloth. Caustic soda or potash in strengths of 2% at 70° C or over alkali sulfides, polysulfides and sulfohydrates or mixtures of ethyl alcohol and ether, ethyl, amyl and butyl acetates, pyridine, ferrous sulfates, and other reducing agents are detrimental to the cloth. [Pg.127]

Other possibilities are the reduction of nitro groups by applying the sample solutions to adsorbent layers containing zinc dust and then exposing to hydrochloric acid vapors [110] 3,5-Dinitrobenzoates and 2,4-dinitrophenylhydrazones can also be reduced in the same way on tin-containing silica gel phases [111] Cellulose layers are also suitable for such reactions [112] Seiler and Rothweiler have described a method of trans-salting the alkali metal sulfates to alkali metal acetates [113]...

Fluorescent cellulose triacetate membranes were prepared by incorporation of pyrene-butyric acid (219), and were applied to in situ detection of ground water contamination by explosives, based on fluorescence quenching by the nitro groups LOD 2 mg/L of DNT (220) and TNT (221) and 10 mg/L for RDX (276) the response follows the Stern-Volmer law for DNT and TNT442.

One of the favored organisms for study of cellulolysis by Trichoderma is T. reesei. Consequently, many mutant strains which hyperproduce cellulase have been obtained by treatment with ultraviolet light, gamma irradiation, the linear accelerator, diethyl sulphate and N-methyl-N -nitro-N-nitroso-guanidine (7). Whereas much of the study of T. reesei has been with cellulose as substrate, it is relevant to consider the other fractions of natural lignocelluloses hemicellulose and holocellulose (the combined cellulose and hemicellulose fraction). [Pg.609]

Other explosives, discovered in the nineteenth century, were nitroglycerine, a liquid that is absorbed in a solid to make dynamite, and nitrocellulose, a solid that produces less smoke (smokeless powder). They are made by heating glycerine and cellulose with nitric acid, a process that adds nitro (-NO2) groups. Another important explosive is trinitrotoluene, made by heating (very carefully) toluene in nitric acid,... [Pg.129]

The DuPont company rapidly saw that HNO3 was the key in making cheap explosives, all of which need nitrates and nitro compounds, and they rapidly became the largest producers of HNO3. World War I was a good period for DuPont, but the explosives business is inherently cyclical (fortunately), and dynamite and fireworks have limited markets. Therefore, DuPont began to explore other uses of cellulose, a raw material for smokeless... [Pg.129]
