Sodium Persulfate is also called sodium sulfate, is an inorganic substance, a chemical formula is Na2S2O8, and the appearance is a white crystal powder, odorless.

The solubility in water was 549 g / L at 20 ° C. Relative density 2.400 (deposit density: 0.7).

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.

Appearance and properties: white or almost white fibrous or granular powder Density: 1.39 g/cm3 Solubility: almost insoluble in absolute ethanol, ether, acetone; swelling in cold water into a clear or slightly dirty colloidal solution Stability: The solid is flammable and incompatible with strong oxidants.

Glycerol, also called glycerol, with the chemical formula c3h8o3, is colorless, odorless, sweet, with a clean and viscous liquid appearance. it's miles an organic substance that may take in moisture from the air, as well as hydrogen sulfide, hydrogen cyanide and sulfur dioxide. insoluble in benzene, chloroform, carbon tetrachloride, carbon disulfide, petroleum ether and oils, it's miles the skeleton factor of triglyceride molecules.

Properties: White or slightly yellow scaly crystals with unique fragrance. Solubility: Insoluble in water, acid and alkali, but soluble in organic solvents such as alcohol, ether and benzene.

Physical nature Colorless concierge fluids have a fierce scent. Insoluble in water, dissolved in ethanol and ether. Benzyl alcohol, paf alcohol, 2-chloroethanol, ethylene glycol, furfural, dimethylformamide and acetonitrile were dissolved at room temperature. No corrosive metal.

Methacrylic acid is colorless crystal or transparent liquid with pungent odor. Soluble in hot water, soluble in most organic solvents such as ethanol and ether. Easily polymerized into water-soluble polymers. Combustible, there is a danger of burning in case of high heat and open flame, and it can produce toxic gas when heated.

Glass material is referred to as a glass instrument. Many glass instruments are used in the laboratory, which is highly chemically stable, thermal stability, and well-transparent, and good insulation function.

The toluene diisocyanate has 2,4-toluene diisocyanates and 2,6-toluene diisocyanate (TDI).

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

Molecular weight: 65.39 Grade: 5N MDL number: MFCD00011291 EC number: 231-175-3

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.
