Why are aromatic hydrocarbons economically friendly in chemical producton?
Best insight from top research papers
Aromatic hydrocarbons are economically friendly in chemical production because they can be produced efficiently and at a higher selectivity using specific catalysts. These catalysts consist mainly of group VIII metals, macroporous zeolites, and halogen compounds . Additionally, the catalysts used in the production of aromatic hydrocarbons cause little deposition of coke, have a long life, and give high yields of the desired compounds . The production of aromatic hydrocarbons also involves controlling the level of carbon oxides in the hydrocarbon stream, which contributes to the economic viability of the process . Furthermore, the reduction of aromatic nitro compounds to obtain aromatic hydrocarbons can be carried out safely and economically using a specific catalyst and hydrogen donors . Finally, the pyrolysis of heavy hydrocarbons in the presence of hydrogen and water vapor allows for the economical production of aromatic hydrocarbons as petrochemical raw materials .

Why molecules with high aromatic rings number are poorly soluble?5 answersMolecules with high numbers of aromatic rings are often poorly soluble due to their structural characteristics. Aromatic rings play a crucial role in various interactions, including protein-drug and protein-protein complexes, influencing stability and molecular recognition. The solubility of compounds can be affected by the thermodynamic characteristics of sublimation and solvation processes, with structural modifications impacting solubility. In the case of black carbon molecules, those with large and highly condensed aromatic structures exhibit low solubility, potentially due to limited interactions with other components in the environment. Additionally, the three-dimensional structure of certain aromatic polyimides can enhance solubility despite their aromatic nature, allowing for easy processing and high thermal stability. Overall, the complex interplay of aromatic structures, molecular interactions, and environmental factors contributes to the solubility challenges of highly aromatic molecules.
What are the economic importance of crude oil?4 answersCrude oil is of great economic importance as it is a vital resource for both developed and emerging economies. It represents a significant proportion of total economic inputs and energy consumption, with expenditures on crude oil products accounting for a substantial share of GDP. Changes in crude oil prices have the potential to dramatically alter the financial performance of economies and the behavior of firms operating within them. The increase in oil prices can lead to inflation and reduce economic growth. Crude oil prices also have a significant impact on exchange rates, inflation, and interest rates. Additionally, the global crude oil price can affect the gross domestic product (GDP) growth and exchange rate of oil-producing countries, impacting their economic development. Accurate prediction models for crude oil prices are crucial for decision-making by investors, businesses, and governments.
What are the properties of aromatic alcohols?5 answersAromatic alcohols have various properties. They can provide unexpected improvements in processing and end use product properties of a wide variety of products, and are useful at a wide range of pH. Aromatic alcohols with intact phenolic groups have been found to protect neurons effectively against oxidative damage and cell death, and this neuroprotective activity is independent of the time the compound is added before the toxin. Polymer/aromatic alcohol compositions have film-forming properties and inhibit the growth of mold fungi. The solubilities of solute gases and vapours in alkan-1-ols have been correlated through the solvation equation, showing a regular progression of solvent properties from methanol to decan-1-ol. A method for producing aromatic alcohols involves continuously supplying an aromatic peroxide-including liquid and a hydrogen-including gas to a reaction vessel containing a catalyst, and adding additional catalyst when the activity of the catalyst descends to a predetermined level.
Do aromaticity affect flammability of hydrocarbon?5 answersAromaticity does affect the flammability of hydrocarbons. The presence of aromatic compounds in hydrocarbon fuel blends increases the emissions of aromatic species, regardless of the engine operating conditions. The flammability characteristics of pure hydrocarbon fluids can be predicted using a structural group contribution method. This method identifies the structural groups that significantly contribute to the overall flammability characteristics, such as auto-ignition temperature, flash point, and upper and lower flammability limits. The use of hydrocarbon-blown foams in rigid foam applications presents a challenge due to their flammable nature. However, various techniques can be employed to improve the flame resistance of hydrocarbon-blown foams, including the use of fire retardants, co-blowing agents, and increased foam indices.
How do aromatic hydrocarbons affect the environment?4 answersAromatic hydrocarbons, such as polyaromatic hydrocarbons (PAHs) and halogenated polycyclic aromatic hydrocarbons (HPAHs), have detrimental effects on the environment. These compounds are persistent, recalcitrant, and can accumulate in the food chain, posing risks to public health. PAHs are released into the environment through industrial activities and incomplete combustion of fossil fuels, while HPAHs can be found in air, sediment, fly ash, and biota samples. Aromatic hydrocarbons are known to exhibit mutagenic, carcinogenic, teratogenic, and toxic effects. They can cause genotoxicity, immunotoxicity, developmental toxicity, and carcinogenesis. These pollutants are difficult to degrade and persist in the atmosphere, soil, and sediment for long durations. Efforts are being made to develop eco-friendly and sustainable methods, such as rhizoremediation, to contain and degrade aromatic hydrocarbons in the environment. Understanding the behavior, physicochemical properties, and emission sources of aromatic hydrocarbons is crucial for effective environmental management and bioremediation strategies.
Are charcoals budget friendly?2 answersCharcoals have varying costs depending on the type and brand. Some charcoals are low in cost and provide economic benefits. The affordability of charcoal is considered a priority factor for consumers. However, it is important to note that the quality and suitability of charcoals for specific uses can vary.
