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.

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

1. Used to produce 1,4-butanediol γ- Butyrolactone, tetrahydrofuran, succinic acid, unsaturated polyester resin, alkyd resin and other raw materials are also used in and pesticides. 2. Act as collector in metal beneficiation. 3. It is used in organic synthesis and also as an intermediate of synthetic fiber. 4. Maleic anhydride is an important basic raw material of unsaturated organic anhydride.

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

N-Methyldiethanolamine is a chemical substance with the molecular formula C5H13NO2. It contains two hydroxyl groups and one amino group.

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

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

Helium is a rare gas. Its English name is Helium, and its element symbol is He. It is a colorless and odorless inert gas. Its chemical properties are not vivid. Under normal conditions, it is difficult to react with other substances.

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).

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

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

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.

Appearance and properties: colorless liquid, almost odorless Molecular weight 90.12 Vapor pressure 0.51 kPa/20℃ Flash point: 43℃ Melting point -70°C boiling point: 135.1°C solubility can be miscible with water and most organic solvents such as ethanol Density (D4) 0.925-0.935

It is a solvent for a variety of coatings and a raw material for preparing dibutyl phthalate, a plasticizer. It is also used in the manufacture of butyl acrylate, butyl acetate, ethylene glycol butyl ether,

Sulfur, white and shiny crystal compounds. The taste is bitter, density is 1.405, and the melting point is 180 to 182 ° C. Decomposition when it is hotter, soluble in water, can be dissolved in ethanol when heating, and is slightly dissolved in ether. During the melting, heterogeneity is partialized to form ammonium thiocyanomylisocyanomylocyne. The raw materials used to make drugs, dyes, resins, and plastic powder, and are also used as a vulcanized promoter for rubber, flotal agents for metal minerals.

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.
