QUÉ SIGNIFICA NITRATION EN INGLÉS
Nitración
La nitración es una clase general de proceso químico para la introducción de un grupo nitro en un compuesto químico orgánico. Más libremente el término también se aplica incorrectamente al diferente proceso de formación de ésteres de nitrato entre alcoholes y ácido nítrico, como ocurre en la síntesis de nitroglicerina. La diferencia entre la estructura resultante de compuestos nitro y nitratos es que el átomo de nitrógeno en los compuestos nitro está unido directamente a un átomo que no es oxígeno, típicamente carbono u otro átomo de nitrógeno, mientras que en nitratos, también llamado nitratos orgánicos, el nitrógeno está unido A un átomo de oxıgeno que a su vez suele estar unido a un átomo de carbono. Hay muchas aplicaciones industriales importantes de la nitración en sentido estricto; Los más importantes en volumen son para la producción de compuestos nitroaromáticos tales como nitrobenceno. Las reacciones de nitración se utilizan especialmente para la producción de explosivos, por ejemplo la conversión de guanidina en nitroguanidina y la conversión de tolueno en trinitrotolueno. Sin embargo, son de gran importancia como intermediarios químicos y precursores. Millones de toneladas de nitroaromáticos se producen anualmente.
definición de nitration en el diccionario inglés
La primera definición de nitración en el diccionario es el acto o proceso de tratamiento con ácido nítrico o un nitrato. Otra definición de nitración es el acto o proceso de conversión a nitrato. La nitración es también el acto o proceso de causar someterse al proceso químico en el que se introduce un grupo nitro en una molécula.
