Abstract

وإنتقائية طويلة الأمد في إنتاج أسيتات فينيل vinyl acetate. Long-term and selective in the production of vinyl acetate and vinyl acetate. 19ملخص: يوفر الإختراع محفز بلاديوم- ذهب ثنائي معدني متغاير الخواصheterogeneous bimetallic palladium-gold catalyst لإنتاج أسيتات فينيل vinyl acetate من ايثيلين ethylene، حمض أستيك acetic acid وأكسجين oxygen. 19 Summary: Provides the invention catalyst Bladiom- gold binary metallic heterogeneous heterogeneous bimetallic palladium-gold catalyst for the production of vinyl acetate ethylene vinyl acetate from ethylene, acetic acid, acetic acid and oxygen oxygen. يحضر محفز من الإختراع أولا بتشكيل غلاف من طلاء مشتت من بلاديوم palladium غروي على سطح مادة تدعيم المحفز، ويوضع فوقها ثاني من فلز ذهب gold metal غروي على سطح مادة تدعيم المحفز. Catalyst brings first of the invention to form a casing dispersant coating of palladium palladium on the surface of the slimy material strengthening of the catalyst, and is placed above the second metal of gold metal on the surface of colloidal gold catalyst material strengthening. يستعمل مركب ذهب عضوي معلني organometallic gold لوضع مشتت الذهب gold على سطح مادة تدعيم المحفز. Using organic compound gold organometallic gold advertisers to put dispersant gold gold on the surface of the catalyst material strengthening. لا يحتاج مركب الذهب العضوي المعدني organometallic gold إلى عملية تثبيت، التي تتسبب عادة في إستبقاء فلز ذهب gold metal منخفض. Organic compound gold metal organometallic gold does not require the installation process, which typically cause the retention of gold metal gold metal low. إن محفز بلاديوم- ذهب palladium-gold مفضل من الاختراع له إستبقاء فلز ذهب gold metal عالي، ويظهر إستمرارية The catalyst Bladiom- gold palladium-gold favorite of the invention has retained gold metal gold metal high, shows the continuity
