1969: First mass-produced product is the anhydrous ammonia applicator – one of the first to use rolling coulters. 1971: Builds the first two-wheeled, 400-bushel grain cart equipped with large-diameter augers for fast unloading, and high-flotation tires for mobility in soft conditions.
1,3-Dimethyl-2-imidazolidinone (DMI) is a cyclic urea used as a high-boiling polar aprotic solvent. [2] It is colourless, highly polar solvent has high thermal and chemical stability. It is a homolog of the related solvent DMPU. It can be prepared from 1,2-dimethylethylenediamine by reaction with phosgene.
In aqueous solution, ammonia deprotonates a small fraction of the water to give ammonium and hydroxide according to the following equilibrium: . NH 3 + H 2 O ⇌ NH + 4 + OH −.. In a 1 M ammonia solution, about 0.42% of the ammonia is converted to ammonium, equivalent to pH = 11.63 because [NH +
Hydroxylammonium chloride is a chemical compound with the formula [NH 3 OH] + Cl −.It is the hydrochloric acid salt of hydroxylamine (NH 2 OH).Hydroxylamine is a biological intermediate in nitrification (biological oxidation of ammonia with oxygen into nitrite) and in anammox (biological oxidation of nitrite and ammonium into dinitrogen gas) which are important in the nitrogen cycle in soil ...
Anhydrous ammonia is classified as toxic (T) and dangerous for the environment (N). The gas is flammable (autoignition temperature: 651 °C) and can form explosive mixtures with air (16–25%). The permissible exposure limit (PEL) in the United States is 50 ppm (35 mg/m 3), while the IDLH concentration is estimated at 300 ppm. Repeated exposure ...
Ammonia borane (also systematically named ammoniotrihydroborate [citation needed]), also called borazane, is the chemical compound with the formula H 3 NBH 3.The colourless or white solid is the simplest molecular boron-nitrogen-hydride compound.
The dinitrogen ligand is not reduced by aqueous sodium borohydride. [6] Nearly all known reactions of this compound are displacement reactions. Pentaamine(halogen)ruthenium(II) halides can be synthesized by treating [Ru(NH 3) 5 N 2] 2+ with halide sources: [4]
The usual active compound is ammonium carbonate—a colorless-to-white, crystalline solid ((NH 4) 2 CO 3). [1] Because most modern solutions are mixed with water, they should properly be called "aromatic spirits of ammonia". [1]
