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

La piridina es un l\u00edquido incoloro e higrosc\u00f3pico con un olor penetrante, a pescado y amina. Es miscible con agua y con la mayor\u00eda de los disolventes org\u00e1nicos; su punto de ebullici\u00f3n es 115,2 \u00b0C, su punto de fusi\u00f3n -41,6 \u00b0C, su densidad 0,978 g cm-\u00b3 a 25 \u00b0C, su \u00edndice de refracci\u00f3n 1,510 y su punto de inflamaci\u00f3n 20 \u00b0C. La presi\u00f3n de vapor es de 2,76 kPa a 25 \u00b0C y la temperatura de autoignici\u00f3n de 482 \u00b0C.<\/p>\n

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

La piridina es un disolvente vers\u00e1til y un componente b\u00e1sico de productos agroqu\u00edmicos, farmac\u00e9uticos y de qu\u00edmica fina. Se utiliza para sintetizar vitaminas B3 y B6, antihistam\u00ednicos y anest\u00e9sicos locales, y sirve como precursor de herbicidas como el paraquat y el diquat. En las industrias textil y del caucho acelera la vulcanizaci\u00f3n y ayuda a nivelar los tintes, mientras que su fuerte capacidad de coordinaci\u00f3n lo convierte en un ligando esencial en cat\u00e1lisis y qu\u00edmica anal\u00edtica.<\/p>\n

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

La piridina se suministra en bidones de acero con revestimiento epox\u00eddico de 200 L (190 kg netos), bidones de HDPE con homologaci\u00f3n UN de 25 L (24 kg netos) o botellas de vidrio de borosilicato de 1 L (0,9 kg netos). Almacenar en un lugar fresco, sombreado y bien ventilado, por debajo de 30 \u00b0C, lejos de oxidantes, \u00e1cidos y fuentes de ignici\u00f3n. Mantener los recipientes bien cerrados y conectados el\u00e9ctricamente a tierra durante el trasvase para evitar chispas de electricidad est\u00e1tica.<\/p>","protected":false},"excerpt":{"rendered":"
