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

El alcohol estear\u00edlico es un s\u00f3lido ceroso de color blanco con un leve olor caracter\u00edstico\u3002 Es insoluble en agua pero soluble en disolventes org\u00e1nicos. Este compuesto tiene un punto de fusi\u00f3n de aproximadamente 56-59\u00b0C y un punto de ebullici\u00f3n de 210\u00b0C a presi\u00f3n reducida\u3002 Se utiliza en diversas aplicaciones debido a sus propiedades emolientes y a su capacidad para actuar como emulsionante\u3002.<\/p>\n

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

El octadecanol puede utilizarse en la producci\u00f3n de pingpingol, resinas, caucho sint\u00e9tico y colorantes para pel\u00edculas que recogen el color, etc. El antioxidante 1076 (2082-79-3) puede prepararse haciendo reaccionar octadecanol con \u03b2-(3, 5-di-terc-butil-4-hidroxifenil) metilpropionato con met\u00f3xido de sodio como catalizador y dimetilsulf\u00f3xido como disolvente a 130\u2103 durante 2-3 horas. Se trata de un excelente antioxidante no contaminante y no t\u00f3xico, ampliamente utilizado en poliolefinas, poliamidas, poli\u00e9steres, cloruro de polivinilo, poliestireno, resinas ABS y diversos productos derivados del caucho.<\/p>\n

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

El alcohol estear\u00edlico suele envasarse en sacos o bidones de 25 kg forrados de pl\u00e1stico\u3002 Debe almacenarse en un lugar fresco y seco, alejado de la luz solar directa y de la humedad\u3002 La zona de almacenamiento debe estar bien ventilada para evitar la acumulaci\u00f3n de polvo\u3002 Es importante mantener el producto sellado para conservar su pureza y evitar que absorba la humedad del aire\u3002<\/p>","protected":false},"excerpt":{"rendered":"
