Abstract
ตัวเร่งปฏิกิริยาเป็นประโยชน์โดยเฉพาะอย่างยิ่งในการเตรียมเอสเทอร์ที่ไม่อิ่มตัว เช่น ปฏิกิริยาของเอธิลีน, ออกซิเจน และกรดอะซิติก ในวัฏภาคไอ เพื่อก่อรูปไวนิลอะ ซิเตต ตัวเร่งปฏิกิริยาประกอบด้วยตัวพาที่มีลักษณะเป็นรู ๆ เหมือนรวงผึ้งถูกเคลือบด้วยซิลิกาและการบรรจุแพลเอเดียมและ ทองคำตลอดทั้งเคลือบซิลิกา ตัวเร่งปฏิกิริยาเช่นนี้แสดง ความดันที่ต่ำลงถูกลดลงและสเปชไทม์ซิลค์สูงสำหรับไวนิลอะ ซิเตต The catalyst is especially useful in the preparation of unsaturated esters such as the reaction of ethylene, oxygen and acetic acid in the vapor cycle to form the vinyl acetate catalyst. It consists of a round, honeycomb-like carrier, coated with silica and a palladium and Gold throughout the silica coating Such catalysts are shown. The lower pressure drop and high silks spectroscopy for vinyl acetate.
