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

El anh\u00eddrido maleico, abreviado como EMA, tambi\u00e9n conocido como \"anh\u00eddrido trans-butenedioico\", es el anh\u00eddrido del \u00e1cido trans-butenedioico. A temperatura ambiente, es un s\u00f3lido incoloro o blanco de sabor agrio, con la f\u00f3rmula molecular C4H2O3. Su peso molecular es 98,06. Se obtiene en forma de cristales aciculares a partir de cloroformo o \u00e9ter. Su punto de fusi\u00f3n es de 60\u00b0C, su punto de ebullici\u00f3n es de 82\u00b0C (1,8665 kPa) y su densidad relativa es de 1,31460. Es soluble en acetona, cloroformo y \u00e9ter, y ligeramente soluble en \u00e9ter de petr\u00f3leo. Se disuelve en agua para formar \u00e1cido trans-butenedioico, y forma \u00e9steres cuando se disuelve en alcohol, y puede sufrir reacciones de s\u00edntesis de dienos con compuestos que contienen dobles enlaces conjugados. Es t\u00f3xico e irrita fuertemente las mucosas.<\/p>\n

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

El adiponitrilo se utiliza en la s\u00edntesis de dienos, en la producci\u00f3n de medicamentos, pesticidas, colorantes <\/sub>intermedios, as\u00ed como en la producci\u00f3n de resinas de poli\u00e9ster, resinas alqu\u00eddicas, \u00e1cido maleico y otros \u00e1cidos org\u00e1nicos. Tambi\u00e9n se utiliza como conservante de grasas y aceites, y es materia prima para resinas de poli\u00e9ster insaturado, resinas alqu\u00eddicas y yodamina de larga duraci\u00f3n. Tambi\u00e9n es un mon\u00f3mero copol\u00edmero para resinas de poli\u00e9ster insaturado, resinas alqu\u00eddicas y copol\u00edmeros de anh\u00eddrido maleico y anh\u00eddrido polimaleico. Tambi\u00e9n es una materia prima qu\u00edmica org\u00e1nica para producir aditivos de tinta, auxiliares de fabricaci\u00f3n de papel, plastificantes, \u00e1cido tart\u00e1rico, \u00e1cido fum\u00e1rico, tetrahidrofurano, etc.<\/p>\n

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

El anh\u00eddrido maleico suele envasarse en sacos de polipropileno de 25 kg o en sacos de escamas de 500 kg. Para su almacenamiento, debe mantenerse en un lugar fresco, seco y bien ventilado, alejado de fuentes de calor y de la luz solar directa. La temperatura de almacenamiento no debe superar los 25\u00b0C para garantizar su estabilidad. Es fundamental almacenarlo de forma que se evite la entrada de humedad y la contaminaci\u00f3n.<\/p>","protected":false},"excerpt":{"rendered":"
