RESUMEN

La obtención de la resina tereftálica utilizada y  PET  como material reciclable contaminante (sólido no degradable) con indicadores superiores a 1500000 toneladas métricas distribuidas en el planeta. El método activo y los procedimientos para la degradación del PET (contaminante activo mundial) se realizó mediante la reacción cinética  de aditivos anhídrido maleico para la obtención de una resina tereftálica  con viscosidad de 320 cps y una acidez de PH  2.8 para múltiples aplicaciones en la industria naval, mueble, detalles.
 
Se realizó este estudio para contribuir en lo que es poder minimizar en gran parte la contaminación que se produce a diario debido a este tipo de material (Pet). Por lo cual con la ayuda de este prototipo de reactor tipo batch se pudo realizar la degradación del Pet, se espera que dicho proceso sea implementado en el Laboratorio de Operaciones Unitarias de la Facultad de Ingeniería Química de la Universidad de Guayaquil. Como sabemos que el Pet es un material que tarda años en degradarse, provocando así un gran impacto ambiental por su excesiva utilización en todo el planeta, y por lo cual es de mucha importancia este estudio para la realización de este tipo de proceso para la población estudiantil. El equipo se armó con acero inoxidable, con un sistema de agitación que consta con (un motor de 0.5 Hp y un eje transmisión de 3 paletas), un tanque de 2.75 lts., y utilizando una fuente de energía de 110V. Los principales métodos utilizados dentro de esta investigación es la degradación  por medio de Glicólisis para así obtener el ácido tereftálico y etilen glicol como residuo, el otro método a seguir es una reacción en cadena del producto obtenido en el primer método con algunos aditivos para así obtener la resina tereftálica. Los resultados obtenidos dentro de esta investigación fueron satisfactorios ya que se obtuvo la resina tereftálica, con olor, color, textura con viscosidad de 320 cps y una acidez de 28, las cuales son características propias de esta resina.

KINETIC STUDY OF THE REACTION TO THE OBTAINING OF THE RESIN TEREFTÁLICA USING MALEIC ANHYDRIDE.

SUMMARY

Obtaining terephthalic PET resin used as a pollutant and recyclable material (solid non-degradable) with greater than 1500000 metric tons distributed on the planet indicators. The active method and procedures for the degradation of PET (global active contaminant) was performed using kinetic reaction of maleic anhydride additives obtaining a terephthalic resin with viscosity of 320 cps and an acidity of pH 2.8 for many applications in industry naval, furniture, details.
 
This study was conducted to contribute to what is to minimize the pollution that occurs daily due to this type of material (Pet) largely. Therefore with the help of this prototype batch type reactor could be performed Pet degradation, it is expected that this process is implemented in the Laboratory of Unit Operations of the Faculty of Chemical Engineering at the University of Guayaquil. As we know that PET is a material that takes years to degrade, causing a major environmental impact due to its excessive use around the world, and so it is very important this study to carry out this type of process for the population student. The team was assembled with stainless steel, with a stirring system consisting with (0.5 Hp engine and transmission shaft 3 pallets), a tank of 2.75 liters., and using a 110V power source. The main methods used in this research is the degradation by means of glycolysis to obtain terephthalic acid and ethylene glycol as a residue, other method to follow is a chain reaction of the product obtained in the first method with some additives to obtain the terephthalic resin. The results obtained in this research were satisfactory since the terephthalic resin was obtained, with odor, color, texture with viscosity of 320 cps and an acidity of 28, which are characteristic of this resin features.
