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.

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.

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. Generally, the concentration of lactic acid in the blood is from 1-2 mmol / L during non-exercise, and can rise to 20 mmol / L during intense exercise.

The melting point is 13.5°C, the boiling point is 140.9°C, and the density (20/4°C) is 1.0611g/cm3. The chemical nature is lively. It is easy to polymerize in air and can be reduced to propionic acid by hydrogenation. Addition with hydrogen chloride generates 2-chloropropionic acid. Used in the preparation of acrylic resins and other organic synthesis. It is made by oxidation of acrolein or hydrolysis of acrylonitrile, or made by carbon monoxide, acetylene and water under the action of nickel catalyst.

Sulfonated cobalt phthalocyanine is an effective catalyst for removing mercaptan in light oil. Gasoline containing sour crude oil has a relatively high sulfur content.
Hydrogen peroxide, also known as peroxide, is a low-toxic substance, but if used improperly, it can still cause harm to the human body. Next, I will introduce you to the use of hydrogen peroxide and its hazards.
Hydrogen peroxide is a good oxidizing bleaching agent. It is used for bleaching yarns with hydrogen peroxide. It has good whiteness, pure color and no impurities in the equipment.
Hydrogen peroxide is also known as hydrogen peroxide, and its chemical formula is H2O2. Its appearance is a light blue viscous liquid, which can be mixed with water at will. It is an oxide and reducing agent, but the effect of hydrogen peroxide in different situations There are also certain differences. Today, let us talk about the actual effects of hydrogen peroxide in different uses.
Ammonia is an aqueous solution of ammonia. It is colorless, transparent and has a pungent smell. So what are the properties of ammonia?
Storage conditions of flammable and explosive risk chemicals, such as methylamine ethanol solution and methylamine methanol solution.
Ammonia water, also known as Ammonia water, is a solution of ammonia dissolved in water, is colorless and transparent liquid, has a special irritating odor, volatile, corrosive, weak alkaline, unstable and flammability and other characteristics.
N-Methyldiethanolamine (MDEA) is commonly used to solve the acid gas containing hydrogen sulfide and CO2 in industrial production. It can absorb hydrogen sulfide and part of CO2.
Glycerol (also known as glycerol) is an organic substance that is colorless, odorless, sweet in taste, and has a clear, viscous appearance. It is miscible with any proportion of water, alcohol, amine and phenol, and the aqueous solution is neutral. Glycerin is a polyhydric alcohol humectant, and the hydroxyl groups form hydrogen bonds with water molecules in the molecular structure, which plays a good role in absorbing water and locking water. Glycerin has a wide range of uses, with more than 1,700 uses currently in use in food and industry.
The bis-sodium sulfate solution is acidic and can be decomposed by alcohol and silver ions. It can also burn with combustibles or easy oxides to support combustion, promote fire, and even explode when it is violent.
