  Our company provides naphtha cutting, reforming C9 crude aromatics separation, and reforming crude aromatics separation technology such as C10 crude aromatics separation. Our company's crude aromatics separation process has the advantages of advanced process flow, high process flexibility, low process energy consumption and high yield. With the separation of C10 crude aromatics from 60 thousand tons / year as an example, the high boiling point solvent products have the characteristics of high aromatic content, strong solubility, low toxicity, small smell, high flash point, high boiling point, moderate volatilization speed and stable chemical and physical properties. It has no chlorine and heavy metals. Its physical and chemical properties are stable and leveling is good. Its solubility is excellent. Especially in the later stage of evaporation, it can exert high dissolving force, so that the smoothness of the coating is good without orange peel and gloss. In addition, it can also...

  We are   Isobutyl Acetate Technology Provider   and today we will introduce the technology of   Isobutyl Acetate Production . Isobutyl acetate, an esterified product of acetic acid and 2- butanol, is a colorless transparent liquid at room temperature. It dissolves with ethanol and ether, dissolves in water, flammable, and has mature fruit flavors. It is mainly used as a solvent for nitrocellulose and lacquer, as well as chemical reagents and spices. Isobutyl acetate has the typical properties of ester, including hydrolysis, alcoholysis, ammoniation, Grignard reagent and alkyl lithium addition, catalyzed hydrogenation and reduction of lithium aluminum hydride (lithium aluminum hydride), and the condensation reaction of Claeson ester (Claisen condensation) itself or with other esters. Isobutyl acetate can be qualitatively detected by hydroxylamine hydrochloride (NH2OH. HCl) and ferric chloride (FeCl). Other esters, acyl halides and anhydride will affect the inspectio...

Melting point 208~212 ° C, relative density 1.03~1.09. Soluble in acetone, ethanol, ether, insoluble in water . U se   This product( Antioxidant BBMC Device ) is a non-polluting antioxidant suitable for polypropylene, polyethylene, ethylene-vinyl acetate copolymer, polystyrene, ABS resin, polyamide, polyacetal, polyvinyl chloride and cellulose resin. Often used together with thiodipropionate dilaurin, thiodipropionate di(octadecyl alcohol), phosphite and organotin compounds, have a good synergistic effect, can further improve the thermal oxygen stability, generally Dosage 0.01~0.5 parts.

  Since 1959, the United States dupont developed polyformaldehyde (Polyxymethylene, POM) and industrial production, POM with its superior performance in the automotive, electronic appliances, consumer goods, machinery industry etc widely application, rapid development and become one of the five engineering plastics. As a kind of high performance engineering plastics, POM had "taken steel", "super steel", it has good physical and mechanical properties, chemical resistance character, using a wide temperature range, can be use for a long time between - 40 ℃ ~ 100 ℃. The POM, which costs less than many other engineering plastics, is replacing markets traditionally dominated by metals, such as zinc, brass, aluminum and steel, by making many parts. At present, POM has been successfully applied in many fields, such as electronic, electrical, mechanical, instrument, daily use light industry, automobile, building materials, agriculture, etc. POM also shows a good growth tren...

  China's new energy resources are complete in variety, number, and abundant in resources. Solar energy, wind energy, and biomass energy resources are abundant, as well as geothermal energy and ocean energy, which can be used for large-scale long-term development and utilization. In recent years, China has made remarkable achievements in the development and utilization of solar energy and wind energy. Many technologies, such as solar greenhouses, solar cookers, solar water heaters, and solar dryers, have been widely used in rural and urban areas; wind power has risen rapidly and has experienced rapid growth. At the same time, we must also use chemical methods to increase energy efficiency.  Phenol Alkylation Technology  is a good choice.

  The strategy is supported by three sub-strategies: The first is to save energy, improve energy efficiency, and control total volume. The total amount of energy consumed to achieve the third-step strategic objectives, especially the total amount of fossil fuels such as coal and oil, will be minimized. The second is the efficient and clean use of fossil energy, so that this black energy gradually "green." At present, coal is the dominant energy source, and its proportion in total energy resources should be gradually reduced. In 2050, it can be reduced to less than 40%. The third is to accelerate the development of nuclear energy and renewable energy so that it will gradually become the green pillar of national energy. Nuclear power is recognized as a renewable energy source. At present, China's nuclear power plants are all thermal reactors, and fast reactors have already been started. The next step will be fusion reactors. This is a trilogy of China's nuclear energy. ...
