Abstract
------13/07/2561------(OCR) หน้า 1 ของจำนวน 1 หน้าบทสรปการประดิษฐ์การประดิษฐ์นี้มีวัตถุประสงค์ที่จะนำเสนอตัวเร่งปฏิกิริยาที่สามารถใช้ผลิตกรด a, P -คาร์บอกซิลิกที่ไม่อิ่มตัวด้วยผลของปฏิกิริยาที่ดีผ่านทางการทำปฏิกิริยาออกซิเดชั่นในวัฏภาคของเหลวของโอเสทิเนหริอ a , P -อัลดีไฮด์ที่1ไม่อิ่มตัว, วิธีการผลิตสิ่งเดียวกันนี้, และวิธีการผลิตกรด a , P -คาร์บอกซิลิกที่ไม่อิ่มตัวซึ่งใช้ตัวเร่งปฏิกิริยาดังกล่าว ในการประดิษฐ์นี้จะเกิดตัวเร่งปฏิกิริยาสำหรับใช้ผลิตกรด a 1 P -คาร์บอกซิลิกที่ไม่อิ่มตัวซึ่งมีโลหะถูกรองรับบนพาหะที่มีปริมาตรรูพรุนรวมที่วัดได้โดยวิธีการดูดซับก๊าซไนโตรเจน 0.40 - 1.50 มล./กรัม หรือตัวเร่งปฏิกิริยาสำหรับใช้ผลิตกรด a, P -คาร์บอกซิลิกที่ไม่อิ่มตัวซึ่งมีพาลาเดียมที่มีฃนาดเส์นผ่านศูนย์กลางอนุภาคโดยเฉลี่ยในช่วง 1 - 8 นาโนเมตร ถูกจับยึดไว้ที่พาหะ ------------ ------ 13/07/2018 ------ (OCR) page 1 of number 1 page Invention This invention aims to present a catalyst that can be used to produce acid a, P - unsaturated carboxylic with good reaction effect through oxidation in the liquid phase of the osmotene, a, P - unsaturated 1st aldehyde. , A method for producing the same thing, and a method for producing acid a, P - unsaturated carboxylic acids using such catalysts. In this invention, a catalyst for the production of a 1 P - unsaturated carboxylic acid with metal is supported on a carrier with a total pore volume measured by the nitrogen gas adsorption method of 0.40. - 1.50 ml / g, or catalyst for the production of a, P - unsaturated carboxylic acid with palladium with an average of 1 - 8 nanoparticles. The meter is clamped to the carrier ------------
