Abstract
กรรมวิธีที่ดีขึ้นซึ่งใช้สำหรับการเตรียมไดเมอร์ 2,2-พาราไซโคลเฟนซึ่งใช้ประโยชน์เป็นสารตั้งต้นสำหรับแพริรินซึ่ง เป็นสารเคลือบแบบรูปร่างที่ใช้ในอุสาหกรรมอิเลกโทรนิกส์ สำหรับป้องกันส่วนประกอบอิเลกโทรนิกส์ที่มีสภาพไวหลายชนิด กรรมวิธีนี้ประกอบด้วยการทำปฏิกิริยาการกำจัดแบบฮอฟมานน์ ของp-เมธิลเบนซิลไทรเมธิลแอมโมเนียม, ไฮดรอกไซด์ที่ปกติให้ ผลผลิตของไดเมอร์ต่ำเพื่อให้ได้ผลดีที่สุดโดยการทำ ปฏิกิริยาการกำจัดในที่มีตัวทำละลายร่วมและตัวส่งเสริม ปฏิกิริยาบางอย่างอยู่ด้วย Improved process used for the preparation of dimers. 2,2-paracyclofen, used as a precursor to parryins, which It is a contoured coating used in the electronics industry. For protection of various sensitive electronic components This process consists of a hofmann type removal reaction. Of p-methyl benzyl trimethylammonium, hydroxide that normally provides Low Dimer yield To get the best results by doing Elimination reactions in the presence of cofrevents and promoters Some reactions were there.
