\n1.Propiedad del producto<\/h3>\n

 <\/p>\n

El n-heptano es un l\u00edquido incoloro y transparente con un ligero olor a gasolina. Es inmiscible con el agua, pero libremente miscible con etanol, \u00e9ter diet\u00edlico, acetona, cloroformo, benceno y tetracloruro de carbono. La sustancia tiene un punto de fusi\u00f3n de -91 \u00b0C, un punto de ebullici\u00f3n de 98 \u00b0C, una densidad de 0,71 g cm-\u00b3 a 20 \u00b0C y un punto de inflamaci\u00f3n de -4 \u00b0C, lo que la clasifica como altamente inflamable con un rango de explosividad de 1,05-6,7 % v\/v en el aire.<\/p>\n

3.\u00c1mbito de aplicaci\u00f3n y uso<\/h3>\n

 <\/p>\n

El n-heptano sirve como combustible de referencia principal para determinar el punto cero en la escala de octanaje y se utiliza ampliamente como disolvente apolar en espectroscopia, cromatograf\u00eda y extracci\u00f3n farmac\u00e9utica. Se emplea como medio de reacci\u00f3n en s\u00edntesis org\u00e1nica para reacciones de Grignard y Friedel-Crafts, como agente de limpieza de componentes electr\u00f3nicos e instrumentos de precisi\u00f3n, y como disolvente portador en adhesivos, revestimientos y procesamiento de caucho. Los laboratorios lo utilizan para la recristalizaci\u00f3n, el fraccionamiento de pol\u00edmeros y como patr\u00f3n en la calibraci\u00f3n de instrumentos anal\u00edticos.<\/p>\n

4.Embalaje y almacenamiento<\/h3>\n

Bid\u00f3n de acero de peque\u00f1a abertura Caja de madera ordinaria fuera de la ampolla; Botellas de vidrio de boca roscada, botellas de vidrio de boca prensada con tap\u00f3n de hierro, botellas de pl\u00e1stico o bidones met\u00e1licos (latas) en cajas de madera ordinarias.Durante el transporte, los veh\u00edculos de transporte deben estar equipados con los tipos y cantidades correspondientes de equipos contra incendios y dispositivos de manipulaci\u00f3n de emergencia en caso de fuga. En verano, es preferible realizar el transporte por la ma\u00f1ana y por la noche. Los veh\u00edculos cisterna (armario) utilizados para el transporte deben disponer de cadenas de puesta a tierra, y se pueden colocar agujeros y tableros divisorios en el interior de la cisterna para reducir la electricidad est\u00e1tica causada por las vibraciones. Est\u00e1 estrictamente prohibido mezclar y transportar con oxidantes, productos qu\u00edmicos comestibles, etc. Durante el transporte, debe protegerse de la luz solar directa, la lluvia y las altas temperaturas.<\/p>","protected":false},"excerpt":{"rendered":"
