Se trata de una mezcla de tres is\u00f3meros estructurales: orto-xileno (o-xileno), meta-xileno (m-xileno) y para-xileno (p-xileno), cada uno de ellos con aplicaciones industriales espec\u00edficas. Clasificado como l\u00edquido inflamable de clase 3 (n\u00famero ONU 1307), el xileno tambi\u00e9n est\u00e1 etiquetado como sustancia nociva debido a sus efectos toxicol\u00f3gicos en el cuerpo humano.<\/p>\n

Peso molecular<\/td>\n106,17 g\/mol<\/td>\n<\/tr>\n
Apariencia<\/td>\nL\u00edquido incoloro y transparente; olor dulce y arom\u00e1tico<\/td>\n<\/tr>\n
Propiedades f\u00edsicas clave<\/td>\nPunto de fusi\u00f3n: -47,4 \u00b0C (is\u00f3meros mixtos); punto de ebullici\u00f3n: 138\u2013144 \u00b0C; densidad: 0,86\u20130,87 g\/cm\u00b3 (20 \u00b0C); vol\u00e1til; insoluble en agua, miscible con etanol, \u00e9ter, acetona y la mayor\u00eda de los disolventes org\u00e1nicos<\/td>\n<\/tr>\n
Grados de pureza<\/td>\nGrado industrial (\u226598,51 TP3T de is\u00f3meros mixtos); grado de alta pureza (\u226599,91 TP3T de un solo is\u00f3mero para s\u00edntesis qu\u00edmica); grado de disolvente (para recubrimientos e impresi\u00f3n)<\/td>\n<\/tr>\n
M\u00e9todo de producci\u00f3n<\/td>\nSe obtiene principalmente a partir del refinado del petr\u00f3leo (reformado catal\u00edtico de la nafta) y de la destilaci\u00f3n del alquitr\u00e1n de hulla; los is\u00f3meros individuales se separan mediante destilaci\u00f3n fraccionada o cristalizaci\u00f3n<\/td>\n<\/tr>\n<\/tbody>\n<\/table>\n

Principales aplicaciones<\/h3>\n

S\u00edntesis qu\u00edmica:<\/strong> Los is\u00f3meros simples son materias primas fundamentales:<\/p>\n

p-xileno:<\/strong> Produce \u00e1cido tereft\u00e1lico (TPA) y \u00e1cido tereft\u00e1lico purificado (PTA), componentes fundamentales de las fibras de poli\u00e9ster y las botellas de pl\u00e1stico.<\/p>\n

o-xileno:<\/strong> Sintetiza anh\u00eddrido ft\u00e1lico, que se utiliza en plastificantes, resinas y colorantes.<\/p>\n

m-xileno:<\/strong> Fabrica \u00e1cido isoft\u00e1lico, destinado a resinas alqu\u00eddicas y recubrimientos.<\/p>\n

Disolvente industrial:<\/strong> El xileno mixto es un disolvente universal que se utiliza en pinturas, recubrimientos, adhesivos, tintas de impresi\u00f3n y en el procesamiento del caucho; disuelve eficazmente resinas, pigmentos y pol\u00edmeros org\u00e1nicos.<\/p>\n

Industria petroqu\u00edmica:<\/strong> Se mezcla con la gasolina para mejorar el \u00edndice de octano y la eficiencia de la combusti\u00f3n.<\/p>\n

Laboratorio y medicina:<\/strong> Se utiliza como disolvente para la extracci\u00f3n de muestras, la purificaci\u00f3n y la histolog\u00eda (preparaci\u00f3n de tejidos en laboratorios de patolog\u00eda).<\/p>","protected":false},"excerpt":{"rendered":"
