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.

Lactic acid is a carboxylic acid, the molecular formula is C3H6O3, containing a hydroxyl group, belonging to α-hydroxyory (AHA). In an aqueous solution, the carboxyl group releases a proton to generate lactate ion CH3CH (OH) COO-.

Generally speaking, when the energy of the arrangement cannot be satisfied with oxygen breathing, it is arranged that the oxygen that cannot be obtained may not satisfy the quick treatment of oxygen, the concentration of lactic acid will rise. In this case, the acetone dehydrogenase cannot be converted to acetyl coenzyme a, pyruvate start-up. In this case, if the lactate dehydrogenase does not reduce the reduction of pyruvic acid as lactic acid, the composition of triphosphate is inhibited.

The lactate dehydrogenase is converted to a left lactic acid during the fermentation process. Lactic acids are constantly occurring in general metabolism and motion, but its concentration generally does not rise. Only in the lactic acid occurs, lactic acid cannot be transported in time to increase. The lactic acid transport speed is affected by a series of factors, and includes a monocarboxy-dient, lactate dehydrogenase concentration and isomer form, and the oxidative capacity arranged.

Ricia oil contains a lot of ricic acid (more than 80%), so many unique properties.

Chemical nature: Forbidden qualitative: strong oxidizing agent, strong reducing agent, strong acid, strong base. Ecological nature: Ecotoxicity EC50: 1.2 ~ 1.51mg / L (luminous bacteria, microtox toxicity test) Biodegradability Miti-I test, initial concentration of 100 mg / L, sludge concentration 30 mg / L, 2 weeks later degraded 77%. Non-biodegradability In the air, when the hydroxyl radical concentration is 5.00 × 105 / cm3, the degradation of the half-life is 7.8d (theory). Other harmful effects The material is damaged by the environment and should pay spe

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 .

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.

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.

Antioxidant is a kind of chemical substance. When it is only a small amount in the polymer system, it can delay or inhibit the progress of the polymer oxidation process, thereby preventing the aging of the polymer and prolonging its service life. It is also called " Anti-aging agent".

Common tetra-group lead, ferrocene, MMT (methylcyclopentadiene trikarbonyl manganese) or CMT is common, because metal deposits can occur in the inside of the launching machine, resulting in a cylinder wear, spark plug ignition Poor problems such as poisoning, oxygen sensors and ternary catalysts, have been prohibited or constrained. The addition of tetra-element and ferrocene added is known as national standards, and the manganese-based anti-explosive agent is strictly constrained (the detection limit is less than 0.018 g / L).

In fact, any kind of antioxidant can not fully meet these conditions. Therefore, in actual application, it is often based on the variety, use and processing method of engineering plastics, using the strengths of various additives and cooperating to produce synergistic effects.

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.

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

For diesel vehicles such as heavy trucks and passenger cars to meet the National IV emission standards, a suitable SCR system must be selected for exhaust gas treatment, and this system must use urea solution to treat nitrogen oxides in the exhaust gas. Therefore, urea solution for vehicles has become an essential product for heavy-duty trucks and passenger cars to meet the National IV emission standards.
