Who invented smokeless powder Ballistite in 1887?
Smokeless powder removed. Krupp began adding diphenylamine as a stabilizer in 1888. Meanwhile, in 1887, Alfred Nobel obtained an English patent for a smokeless gunpowder he called Ballistite. In this propellant the fibrous structure of cotton (nitro-cellulose) was destroyed by a nitro-glycerine solution instead of a solvent. In England in 1889, a similar powder was patented by Hiram Maxim, and in the United States in 1890 by Hudson Maxim. Ballistite was patented in the United States in 1891. The Germans adopted ballistite for naval use in 1898, calling it WPC/98. The Italians adopted it as "filite", in cord instead of flake form,
Smokeless powder Works began producing a mixture of nitroglycerine and nitrocellulose with ammonium picrate as "Peyton Powder", Leonard Smokeless Powder Company began producing nitroglycerine-nitrocellulose "Ruby" powders, Laflin & Rand negotiated a license to produce "Ballistite", and DuPont started producing smokeless shotgun powder. The United States Army evaluated 25 varieties of smokeless powder and selected "Ruby" and "Peyton Powders" as the most suitable for use in the Krag-Jørgensen service rifle. "Ruby" was preferred, because tin-plating was required to protect brass cartridge cases from picric acid in the "Peyton Powder". Rather than paying the required royalties for "Ballistite", Laflin & Rand financed Leonard's reorganization
