Para-nitroacetanilide, also known as 4-nitroacetanilide, is an organic compound with the chemical formula C8H9NO3. It is a white, crystalline solid that is soluble in organic solvents such as ethanol and acetone, but relatively insoluble in water.
Para-nitroacetanilide is a member of the class of compounds known as nitro compounds, which contain a nitro group (-NO2) attached to an aromatic ring. Nitro compounds are known for their explosive properties, and para-nitroacetanilide is no exception. In fact, it has been used as a substitute for TNT (trinitrotoluene) in the manufacture of military explosives.
In addition to its use in the production of explosives, para-nitroacetanilide has a number of other industrial applications. It is used as a starting material for the synthesis of dyes, pigments, and pharmaceuticals. It is also used as a herbicide, a fungicide, and a molluscicide.
Para-nitroacetanilide is classified as a hazardous substance by the Environmental Protection Agency (EPA) due to its potential to cause serious health effects in humans. Short-term exposure to high levels of para-nitroacetanilide can cause symptoms such as dizziness, headache, nausea, and vomiting. Long-term exposure may increase the risk of cancer and other serious health problems.
Despite its potential dangers, para-nitroacetanilide continues to be widely used in industry due to its versatility and effectiveness. As with any chemical compound, it is important to handle para-nitroacetanilide with caution and to follow proper safety protocols when working with it.
Preparation of p
The resulting precipitate of p-nitroacetanilide is filtered and washed free of acid, using approximately 36,500 parts of- Water. Utilice precaución extrema tanto al preparar como al usar esta mezcla. La nitración se origina ordinariamente tratando los compuestos aromáticos con una mezcla de ácido nítrico y sulfúrico concentrados. Se usa en la producción de p-nitronilida que se usa para intermedios de colorantes, especialmente rojo de p-nitronilida, inhibidores de gomas de gasolina, inhibidores de corrosión. All aspects of p-Nitroacetanilide, including general information, preparation, and properties, are discussed in this curated p-Nitroacetanilide study material.

They result in two products of nitrified P-nitroacetanilide and o-Nitroacetanilide. OBTENCION DE LA P-NITROACETANILIDA Obs: se observa un precipitado amarillo que luego es filtrado en el buchner se elimina las impurezas y nos quedamos con la parte sólida que sería nuestra muestra problema en este caso lo obtenido nitroacetanilina. This deactivation makes the aromatic ring less nucleophile so in the reaction it would take longer to donate electrons to the electrophile. Como consecuencia de ello se sabe con exactitud como llevar a cabo con eficacia el proceso de nitración y también se tienen bastante conocimiento sobre el mecanismo de la nitración aromática que sobre cualquier otra de las reacciones de sustitución aromática. This solution is slowly added with stirring to 2,155 parts of 97. H2SO4 in a beaker. Moreover, it is used to develop poultry medicines, anti-oxidants, gasoline, pesticides, and rubber chemicals.

Generally, it is slightly yellowish. Acetanilide comprises some analgesic properties, owing to which, it is abundantly used in pharmaceuticals. Along with the para product, a trace of ortho product is also formed. Thus, the p-nitro acetanilide can be formed as a major product. Friedel-Crafts acylation of toluene gives mainly all para substitution product and almost no ortho product. Crystallisation is carried out to break the solid-liquid form of p-Nitroacetanilide. Para nitro acetanilide is defined as a chemical compound that is a derivative of nitro acetanilide prepared from the mixture of nitrating and acetanilide.
Si todo el ácido ha sido removido, el producto será color amarillo claro. Example Six hundred parts of acetanilide are dissolved in 366 parts of 45 B. Hence, it is named Para Nitroacetanilide. Moreover, the glacial acetic acid is also used during preparation, as it possesses the properties of a polar solvent, which regulates the acetanilide dissolving. Preparation Preparation of 4'-Nitroacetanilide from acetanilide. Para nitroacetanilide is more soluble in ethanol than ortho nitroacetanilide because p-nitroacetanilide has a symmetric structure compared to o-nitroacetanilide so the polarity of p-nitroacetanilide is higher.
