Hydrazine: The physical properties at room temperature without air, base, reaction water, heated to 3273K, and only 0.1% decomposition, thus, N2 chemical properties substances [3] The most important use of mineral nitrogen is nitrate. There are two natural isotopes of nitrogen: N 14 and N 15 organic hydrazine fuel, which the abundance of nitrogen 14 is 99.625%. Crystal structure: unit cell is hexagonal unit cell. Element type: non-metallic element nitrogen is a colorless, odorless gas. [4] The nitrogen elemental form is usually nitrogen. It is colorless, tasteless and odorless, it is very difficult to have a chemical reaction chemically inert gas, and it does not support combustion. Ingredients: high purity nitrogen ≥99.999%; Industrial grade one ≥99.5%; two ≥98.5%. Appearance: colorless, odorless gas. Solubility: slightly soluble in water, ethanol. Main purposes: for ammonia, nitric acid system, used as material protection agents, refrigerants. Hydrazine: forming a covalent bond with the N atom electronegativity higher non-metal-forming compound to form a covalent bond following categories: ⑴N take sp3 hybridization state atom, forming three covalent hydrazine manufacturers, keep a lone electron pairs, the molecular structure of a triangular cone, such as NH?, NF?, NCl? and so on. If the formation of four covalent bond, the molecular structure of a regular tetrahedron type, such as NH? + Ions. ⑵N take sp2 hybridization state atom, forming two covalent double bond and a single bond, and retain a lone pair of electrons of angular molecular structure, such as Cl-N = O. (N atoms and Cl atoms form a σ bond and a π bond, a lone electron pair on the N atom of the molecule becomes angular.) If there is no lone pair of electrons, the molecular structure of a triangle, for example HNO? Molecule or NO ? - ions. N atoms in the molecule nitric acid, respectively, three O atoms to form three σ-bonded ammonia cleaner, a single pair of π electrons and two O atoms of its π electrons orbit a three-center four-electron delocalized π key. In the nitrate ion, three O to form a four-center six delocalized electrons big π bond between the central atom and the N atom. This structure allows N atoms apparent nitric acid oxidation number +5, due to the large π bond, nitrate under ordinary conditions is sufficiently stable. ⑶N take sp hybridized atom, to form a covalent triple bond, and retain a pair of lone electron pairs of linear molecular structure, e.g., N? CN- molecules and structures of N atoms. Organic hydrazine fuel _ Connaught Chemical (certified) _ hydrazine provided by Qingdao-Connaught Chemical Co. Qingdao-Connaught Chemical Co., Ltd.
