Latest Patents

Clark's latest patents include innovative methods for producing high bulk density spheroidal nitroguanidine and triaminoguanidine nitrate. The first patent describes a process for producing high bulk density spheroidal nitroguanidine by forming a solution of 2 to 9 weight percent of nitroguanidine, 0.5 to 2.0 weight percent of methylcellulose, and 0.5 to 2.0 weight percent of partially hydrolyzed poly(vinyl alcohol) in water at temperatures ranging from 50°C to 100°C. The solution is then cooled at a rate of 1 to 20°C per minute until the temperature drops below 40°C. The second patent outlines a method for preparing triaminoguanidine nitrate from relatively impure commercial guanidine nitrate and aqueous hydrazine. This process involves several steps, including the addition of hydrazine to form monoaminoguanidine nitrate, the removal of solid impurities, and the adjustment of pH using nitric acid.
