Sodium peroxide is an inorganic substance with a chemical formula of Na2O2 and a molecular weight of 77.98. Beige powder or granules. The relative density is 2.8.

Can gradually decompose, moist and high temperatures can accelerate decomposition. Can be decomposed by ethanol and silver ion.White crystalline powder.

Potassium hydroxide is strongly alkaline and corrosive, and its properties are similar to sodium hydroxide, which can cause burns. It can absorb water and dissolve in the air, and absorb carbon dioxide to gradually become potassium carbonate. The pH of the 0.1 mol/L solution is 13.5.

White oblique crystals, industrial products are white or light gray lumps or rods. Easily soluble in water, emits a lot of heat of dissolution when dissolved, soluble in ethanol, slightly soluble in ether. It is deliquescent and has strong water absorption. Potassium hydroxide is strongly alkaline and corrosive, and its properties are similar to sodium hydroxide, which can cause burns. It can absorb water and dissolve in the air, and absorb carbon dioxide to gradually become potassium carbonate. The pH of the 0.1 mol/L solution is 13.5.

The industrial neighborl xylene is a raw material, first washes the acid layer to the acid layer colorless, then use 10% sodium hydroxide solution, water is washed to pass, and the aqueous layer is separated, and the calcium chloride is borned with anhydrous carbon. After the distinction is low, the intermediate fraction is collected, that is, a pure product.

N-butanol is an organic compound of the molecular formula C4H10O, which has a strong flame when the colorless transparent liquid is combined.

Amino -alumanate pesticide is a synthetic pesticide developed after organic phosphate. Its general formula is RO (C) NRR. Amino -aminate pesticides generally have no special odor, stable in acidic environments, alkali decomposition, and most varieties are lower toxicate than organic phosphate

HCFC-141b (monofluorodichloroethane) is a high-purity liquid widely used in cleaning and solvent fields. Because its damage to the ozone layer is 1/10 of CFC-113, it is designated as an ideal substitute for fully halogenated chlorofluorocarbons. HCFC-141b is a widely used non-perhalogenated chlorofluorocarbon. Although its destructive effect on the ozone layer has been greatly reduced compared to fully halogenated chlorofluorocarbons, it can still cause damage to the ozone layer that is difficult to recover. As a result, its use is gradually being reduced around the world.

Nitrogen, chemical formula is n₂, which is a colorless tasteless gas.

Oxygen is a simple substance composed of oxygen. The chemical formula O2 has more vivid chemical properties, and most of the elements can react with oxygen.

Tributyl acetyl citrate is CAS 77-90-7 chemical substances.

Potassium hydroxide is a common inorganic base with a chemical formula of KOH and a molecular weight of 56.1. It is a white powder or flake solid at room temperature.

The propanol, but also glycerol, chemical formula is C3H8O3, colorless, odorless, sweet, and appearance showing a clear liquid, is an organic substance, can absorb moisture from air, can also absorb hydrogen sulfide, hydrogen cyanide and sulfur dioxide .

Dibenylmethane diisocyanate, referred to as "MDI", is an organic substance, a chemical formula C15H10N2O2.

Hydrogen Peroxide Solution is an aqueous solution of hydrogen peroxide.

This product is the standard configuration of SCR technology, the solution concentration is 32.5% 0.7%, which can effectively reduce exhaust pollution and ensure engine efficiency ;8-stage pretreatment + RO reverse osmosis technology + EDI electrodeionization water purification technology + high-precision filtration and purification to ensure the purity of the solution from the source, Delay SCR scaling, protect the urea pump and pipeline; select ultra-high-purity urea particles, made through multiple purification processes, long-term maintenance of the system and catalyst activity, and prol

The octane is the most important quality indicator of the vehicle gasoline.

It is an efficient catalyst for removing mercaptan in light oil. Gasoline refined from sour crude oil contains higher mercaptan sulfur content.

mercaptan wrapped in fuel is malodorous and corrosive, which reduces the lead content of gas. except, mercaptan is also an oxidation initiator, which can promote the oxidation and condensation of risky components in fuel to gel, resulting in terrible garage balance of gasoline. cobalt phthalocyanine sulfonate is an powerful catalyst for disposing of mercaptan sulfur from heavy oil, and it has the identical effect. whilst in use, dissolve the catalyst in 10% alkali solution, heat it slightly for a time frame, and stir to dissolve it before use.

Chemical reagents are relatively standard substances for chemical research, ingredient analysis, is an important condition for scientific and technological progress, which is widely used in the composition of material, other, qualitative and quantitative analysis.
