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

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.

The molecular weight is 119.16, the melting point is -21°C, the flash point is 127°C, the freezing point is -21°C, and the refractive index is 1.4678. The viscosity (20°C) is 101 MPa·sec.

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.

Phosphorus pentachloride is mainly used as a chlorination reagent for alcohols, carboxylic acids, amides, aldehydes, ketones, enols, and Beckmann rearrangement reagents. It is used as a chlorination agent and catalyst in organic synthesis, and is used in the production of medicines, dyes, and chemical fibers. It is also the raw material for the production of phosphazene chloride and phosphorus oxychloride.

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

Car urea is an essential product for heavy-duty diesel vehicles to meet the National IV emission standards. Vehicle urea refers to an aqueous urea solution with a urea concentration of 32.5% and ultrapure water as the solvent. The raw materials are urea crystals and ultrapure water. 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.

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.

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

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,

Chemical reagents are relatively standard substances for chemical research, ingredient analysis, is an important condition for scientific and technological progress, which is widely used in the composition of material, other, qualitative and quantitative analysis.

it can also be used as high octane gasoline components, is an important raw material for organic chemicals. It can also be used to remove the bitumen of the body. The hospital pathology is primarily used for tissue, slice of pilot and dewaxing.
