Silberrad expls

Nitrol. Early Brit plastic safety expl, patented by O. Silberrad in 1912 (Ref 2). A typical formulation is Nitrol 10, highly. nitrated benzene hydrocarbons 20, collodion cotton 0.5, and AN 69.5%. Under the same name, O. Silberrad took... 

Ref 2). This was followed by Will in 1906 (Ref 3), Silberrad and Phillips in 1908 (Ref 4), and Kast in 1911 (Ref 5). More recently (1938), Hopper of PicArsn (Ref 6) detd and described the expl properties of the following metallic picrates Ai, Cd, Cr, Cu, Fe+3, Fe+2, Na, Ni and Zn. In general,he prepd the salts as cryst hydrates from aq solns by methods outlined by Silberrad Phillips, and Kast. These were then dehydrated by heating at temps of 80 to 150°, depending on the ease with which the w of crystn could be driven off, to obtain the desired degree of hydration... 

Silberrad Explosives. Chlorate and perchlorate expls contg aromatic nitro compds, patented by O. Silberrad in Engl in 1911. Typical formulations contain K chlorate or Amm perchlorate 63-70, MNT 12-14, DNT 6-7, MNN 6-7, woodmeai 5—6, and sol NC (collodion cotton) 0.5 to 2.5%... 

A Azidooniline, Ifts (from eth), mp 62-5 volatile with steam and puffs off on stronger heating very sol in ale, eth-or chlf si sol in w. It was first prepd by heating 4-azidophenyloxamic acid with coned KOH soln (Ref 2). Silberrad Smart (Ref 3) prepd it by slowly distilling acetyl-p-azidoaniline in 40% KOH soln. This compd forms expl salts (Ref 4)... 

Tars, Nitrated. See under Coal Tar and Coal Tar Pitch in Vol 3, C379-R to C380-R Addnl Information Silberrad (Refs 1 4) nitrated neutral coal tar fractions (bp 200—3 50°) and called the product obtained Nitrol . He claimed that it was a HE, suitable for use in expl mixts. Nitrol plasticized or dissolved such aromatic nitrocompds as TNT, TNB, etc, and was suitable for the manuf of plastic safety expls of great durability and power. A typical formulation contained Nitrol 10, a highly nitrated benzene hydrocarbon 20, collodion cotton 0.5, and AN 69.5p...
