Hydrazine hydrate, foaming agents, Jinan days of the chemical hydrazine hydrate, prime oxidation. Urea, chlorine, caustic soda as a starting material, by preparing hydrazine hydrate, and hydrazine hydrate was prepared using the urea generation biuret under the action of sulfuric acid, and then chlorine oxidation in ADC foaming agent, washed, centrifuged, dried to be finished. The product needs to produce one ton of urea (including N≥46%) 2.6 ~ 2.8 tons of sulfuric acid (98%) 2 tons of caustic soda (100% discount) 2.9 to 3.1 tons, 0.1 tons of sodium bromide, chlorine (99.5%) 1.9 to 2.1 tons, from 0.1 to 0.11 tons of potassium permanganate. ADC foaming agent is the largest gas evolution, the most superior performance, versatile foam. It is used in polyvinyl chloride, polyethylene, polypropylene, polystyrene, polyamide, ABC and synthetic rubbers and other materials of hydrazine hydrate: derivative (derivative) refers to a simple compound in which a hydrogen atom or other atom or atomic group is substituted radicals derived more complex product. For example, methane (CH4) as a precursor, the methanol (CH3OH), acetic acid (CH3COOH), chloromethane (CH3Cl), etc. are methane derivative. Such as: a halogenated hydrocarbon, an alcohol price hydrazine hydrate, hydrazine hydrate reducing aldehydes, carboxylic acids can be regarded as derivatives of hydrocarbons, because they are a hydrogen atom is substituted with a hydrocarbon product as halogen, hydroxy, oxygen, etc. Another example: acid halides, acid anhydrides, carboxylic acid derivative is an ester, because they are the hydroxy carboxylic acids substituted with a halogen and an organic group of some products.
