合成的A沸石用盐酸溶液处理,回流4小时,然后用氯化铵溶液处理,再洗涤,干燥;制得的固体在450℃下煅烧1小时,得到了去铝酸和质子(酸)形式的A沸石。得到的A沸石和硫酸用于醋酸和甲醇酯化反应的催化剂。酸性A沸石催化剂的性能决定于酸化方法,显 The synthesized zeolite A was treated with hydrochloric acid solution, refluxed for 4 hours and then treated with ammonium chloride solution, washed again and dried; the solid obtained was calcined at 450 ° C for 1 hour to give the aluminasilicate and proton (acid) A zeolite. The resulting zeolite A and sulfuric acid for the acetic acid and methanol esterification catalyst. Acid A zeolite catalyst performance depends on the acidification method was significantly
