Nitrometer, Dupont

It was invented by lunge in 1890 under the name gasvolumeter (Ref 1). Ten years later, in the USA, it was modified and improved by F.I. duPont and described by Pitman as the duPont Nitrometer (Ref 2). At present, both macro and semi-micro nitrometers are in use, the latter being designed by Elving and Me Elroy (Ref 7)... [Pg.319]

March i960 (Following are some accomplishments a) Modification of DuPont nitrometer by introducing a 2-part bulb. This bulb is recommended for use with PETN and Nitro-guanidine (NGu) (abbr NQ by Roth) This modification is described by M. Roth et al in PATR 2579(1958) b) Introduction of "titanous chloride-buffer method" for detn of NGu in propellants. This method is described by M. Roth R.F. Wegman in Anal-Chem 30, 2036(1958) (See Addnl Ref HH) c) Improved method for detn of stabilizer content. The method is described by M. [Pg.349]

The nitrated product represented the combined nitrate salt nitrate ester of deacetylated chitin. This substance contd one nitric acid salt unit per anhydro-o-glucosamine unit and 1.60-1.65 nitrate ester unit per anhydro-o-glucosamine anhydro -N-acetyl-D -glucosammine units. Attempts to nitrate deacetylated chitin by means of nitrogen pent oxide, in a non-aqueous medium y in the presence of sodium fluoride, by the method of Caesar(Ref 2) were unsuccessful mainly because of occlusion of NaF in the nitrated products(Ref 3)... [Pg.575]
