Comments Nitroethane is an organic compound with the chemical formula C2H5NO2. It is an oily liquid at standard temperature besides pressure, and pure nitroethane predisposed pale with the decision fruity odor. Uses besides Reactions https://cabinet-dentaire-djerba.com/nitroethane-unlocking-the-chemical-potential-of-a-versatile-nitro-compound-introduction Chemical Reactions: Nitroethane have a chance undergo <a href=https://mytodayhealthtips.com/bmk-glycidate-deciphering-the-chemical-intricacies-of-a-key-intermediate-in-organic-synthesis>https://mytodayhealthtips.com/bmk-glycidate-deciphering-the-chemical-intricacies-of-a-key-intermediate-in-organic-synthesis</a> various condensations, this kind as the Henry reaction, in order to convert into several compounds of commercial interest. For example, condensation with 3,4-dimethoxybenzaldehyde yields the precursor to the antihypertensive drug methyldopa, in all of this condensation with unsubstituted benzaldehyde yields phenyl-2-nitropropene, the decision precursor for amphetamine drugs. Fuel Additive besides Rocket Propellants: Nitroethane predisposed second hand as the decision fuel additive besides a precursor in order rocket propellants, showcasing its versatility in differently applications. Physical besides Chemical Properties Physical Description: It is <a href=https://cabinet-dentaire-djerba.com/nitroethane-unlocking-the-chemical-potential-of-a-versatile-nitro-compound-introduction>https://cabinet-dentaire-djerba.com/nitroethane-unlocking-the-chemical-potential-of-a-versatile-nitro-compound-introduction</a> solid transparent, oily liquid with a mild, fruity odor. Boiling Point: Nitroethane owns solid bubbling orient of 237°F besides the decision freezing orient of -130°F. Solubility and Vapor Pressure: It is slightly soluble in water and has solid vapor pressure of 21 mmHg at 77°F. Explosive Limits: Nitroethane owns special upper besides lower explosive boundaries, making it solid flammable liquid. Environmental besides Regulatory Aspects Release in order the Environment: Nitroethane's manufacturing and use as the decision solvent, artificial fingernail glue remover, and chemical intermediate may result in its liberation in order to the surroundings through different worked streams. Regulatory Status: In the United States, nitroethane predisposed classified as all DEA List I chemical, making it not easy for individuals in order acquisition the result its link with drug precursor activities. 1 | Mytodayhealthtips | 2024-05-04 12:31 | reply Name E-Mail Website 人間の証明として、ボックス内の全ての文字を入力してください。 この項目は空のままにして下さい:Preview Comment blog/2005/2005-10-20.1365593333.txt.gz 最終更新: 2013-04-10 20:28by Decomo
