Abstract
Un proceso para preparar alquilén glicoles que incluye hacer reaccionar un oxido de alquileno con agua en la presencia de una combinacion de aditivos yresina de intercambio de aniones, en donde la combinacion de aditivos comprende dioxido de carbonoy una base orgánica o inorgánica provista en una cantidadsuficiente para mantener un pH de la mezcla de reaccion entre aproximadamente 5.0 y 9.0, con la condicion de que, cuando la base es bicarbonato o carbonato,entonces la resina de intercambio deaniones es una resina de intercambio de aniones de trimetil bencil amonio. Un método particularmente preferido de estainvencion es hacer reaccionar oxido de etileno con agua en la presencia de una resina de intercambio anionico de tipo halogenato o bicarbonato (tal como unaresina tipo DOWEXa MSA-1), dioxido de carbono, e hidroxido de carbono. Algunas ventajas de esta invencion son que proporciona tiempo de vida deseable alcatalizador, minimiza el hinchado de la resina, y proporciona una selectividad para alquilén glicol deseable, sostenida.A process for preparing alkylene glycols that includes reacting an alkylene oxide with water in the presence of a combination of additives and anion exchange resin, wherein the combination of additives comprises carbon dioxide and an organic or inorganic base provided in an amount sufficient for maintain a pH of the reaction mixture between about 5.0 and 9.0, with the proviso that, when the base is bicarbonate or carbonate, then the anion exchange resin is an anion exchange resin of trimethyl benzyl ammonium. A particularly preferred method of this invention is to react ethylene oxide with water in the presence of an anion exchange resin of the halogenate or bicarbonate type (such as a DOWEXa MSA-1 type resin), carbon dioxide, and carbon hydroxide. Some advantages of this invention are that it provides desirable alkali life, minimizes swelling of the resin, and provides a desirable, sustained alkyl glycol selectivity.
