\nCaracter\u00edstica estructural:<\/strong> Anh\u00eddrido c\u00edclico formado por la deshidrataci\u00f3n del \u00e1cido ft\u00e1lico, con un anillo de benceno fusionado a un anillo de anh\u00eddrido de cinco miembros<\/p>\n2. Aplicaciones industriales fundamentales<\/h4>\n
\nProducci\u00f3n de plastificantes (principal aplicaci\u00f3n): reacciona con alcoholes (por ejemplo, 2-etilhexanol, butanol) para producir \u00e9steres de ftalato, los plastificantes m\u00e1s utilizados para el cloruro de polivinilo (PVC). Entre los productos clave se encuentran el DOP (ftalato de dioctilo), el DBP (ftalato de dibutilo) y el DINP (ftalato de diisononilo), que mejoran la flexibilidad y la procesabilidad del PVC.
\nResinas polim\u00e9ricas<\/strong>
\nResinas de poli\u00e9ster insaturadas (UPR):<\/strong> Se copolimeriza con glicoles y \u00e1cidos insaturados para producir UPR, que se utiliza en pl\u00e1sticos reforzados con fibra de vidrio (FRP) para embarcaciones, tuber\u00edas y materiales de construcci\u00f3n.
\nResinas alqu\u00eddicas:<\/strong> Se hace reaccionar con polioles y \u00e1cidos grasos para formar resinas alqu\u00eddicas, el componente b\u00e1sico de los recubrimientos industriales, las pinturas y los barnices.
\nColorantes y pigmentos<\/strong>
\nSe utiliza como precursor de los colorantes y pigmentos de ftalocianina, que se emplean ampliamente en el te\u00f1ido de tejidos, las tintas de impresi\u00f3n y la coloraci\u00f3n de pl\u00e1sticos.
\nProductos qu\u00edmicos especializados: se utilizan en la s\u00edntesis de intermedios farmac\u00e9uticos, insecticidas, tensioactivos y retardantes de llama. Tambi\u00e9n act\u00faa como agente de curado para resinas epoxi.<\/p>","protected":false},"excerpt":{"rendered":"
