  1. Acetylen-Methode Unter Verwendung von Zinkacetat auf einem Aktivkohletr\u00e4ger als Katalysator werden Acetylen und Essigs\u00e4ure unter Normaldruck und bei 170-230 \u2103 umgesetzt. Das Reaktionsprodukt wird einer Pulverabtrennung, Gasabtrennung, Aldehydentfernung, Rohdestillation und Rektifikation unterzogen, um gereinigtes Vinylacetat zu erhalten.<\/li>\n
  2. Ethylen-Gasphasenmethode Ethylen, Sauerstoff und Essigs\u00e4ure werden in der Gasphase unter der Bedingung eines Palladium-Gold- (oder Platin-) Katalysators bei 160\uff5e<\/span>180\u2103 und Druck <1MPa, um Vinylacetat zu erzeugen, und dann getrennt und rektifiziert, um feine Produkte zu erhalten.<\/span><\/li>\n
  3. Ethylen-Fl\u00fcssigphasenverfahren Ethylen und Essigs\u00e4ure werden mit Palladiumchlorid-Kupferchlorid als Katalysator umgesetzt, um Vinylacetat zu erhalten.<\/li>\n
  4. Acetaldehyd-Essigs\u00e4ureanhydrid-Methode Unter Verwendung von Acetaldehyd-Essigs\u00e4ureanhydrid als Rohstoff wird zun\u00e4chst Ethylendiessigs\u00e4ure synthetisiert und dann durch eine Essigs\u00e4urereaktion in einem Schritt oder in zwei Schritten synthetisiert.<\/li>\n<\/ol>\n
