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.

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.

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

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 crystal form of citric acid is exclusive due to distinctive crystallization conditions. it's miles barely weathered in dry air and hygroscopic in humid air. when heated, citric acid may be differentiated into diverse merchandise, that could react with acid, alkali, glycerin, and so on.

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-.

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

It uses oxygen with a purity of 93.5%-99.2% and combustible gas (such as acetylene) to produce a flame of extremely high temperature, thereby melting the metal. The metallurgical process cannot do without oxygen. In order to strengthen the production of nitric acid and sulfuric acid, oxygen is also required. Instead of using air, a mixture of oxygen and water vapor is blown into the coal gasifier to obtain coal gas with high calorific value.

Castor oil is the triglyceride of fatty acid, and castor oil is present in the seeds of castor oil, and its content is 35%~57.
