Abstract
La presente invención se refiere a proceso mejorado para obtención de un éter, mediante la reación a una temperatura de 37.7°C a 149°C, y una presión de 3.5 kilos a 52.50 kilos por cm2 manométricos, de un alcohol soluble en agua, como primer reactante y una olefina o alcohol insoluble en agua, como segundo reactante, en una relación molar de primer reactante a segundo reactante de 1-2:1 a 4.0:1 en la presencia de una resina sólida como catalizador de eterificación, formando de este modo, una mezcla de reacción que incluye el primer reactante no-reaccionado, y el éter del producto que tiene radicales del primer reactante y el segundo reactante caracterizado porque las mejoras comprenden poner a reaccionar en un solvente de hidrocarburo inerte, que tiene de 3 a 4 átomos de carbono, el catalizador que comprende de 0.1 a 10 en peso (base seca) de los reactantes y el hidrocarburo inerte, y la relación ponderal del hidrocarburo inerte para cada 100 partes por peso del reactante y poniendo en contacto la mezcla de reacción que contiene el solvente de hidrocarburo inerte con un extractante acuoso formado con ello un extracto acuoso que tiene el primer reactante y un finado que contiene el hidrocarburo inerte y el éter del producto recuperando el refinado.(ver gaceta).The present invention refers to an improved process for obtaining an ether, by reacting at a temperature of 37.7 ° C to 149 ° C, and a pressure of 3.5 kilos to 52.50 kilos per cm2 gauge, of a water soluble alcohol, such as first reactant and a water-insoluble olefin or alcohol, as the second reactant, in a molar ratio of first reactant to second reactant of 1-2: 1 to 4.0: 1 in the presence of a solid resin as an etherification catalyst, thereby forming Thus, a reaction mixture that includes the first unreacted reactant, and the product ether that has radicals from the first reactant and the second reactant characterized in that the improvements include reacting in an inert hydrocarbon solvent, which has from 3 to 4 carbon atoms, the catalyst comprising 0.1 to 10 by weight (dry basis) of the reactants and the inert hydrocarbon, and the weight ratio of the inert hydrocarbon for each 100 parts by weight of the reactant and setting e I contacted the reaction mixture containing the inert hydrocarbon solvent with an aqueous extractant, thereby formed an aqueous extract having the first reactant and a product containing the inert hydrocarbon and the product ether recovering the raffinate (see gazette).
