Abstract

DC60 (25/08/47) ใช้อนุพันธ์ควิโนน เมไธด์ เช่น 4-เบนซิลอิดีน-2,6-ได-tert-บิวทิล-ไซโคลเฮกซะ-2,5- ไดอีโนนเพื่อยับ ยั้งการพอลิเมอไรซ์สไทรีน มอนอเมอร์ในส่วนของเครื่องดี ไฮโดรจิเนทของระบบ การผลิตสไทรีน มอนอเมอร์ ตัวยับยั้ง สัมผัสกับกระแสไหลออกของการดีไฮโดรจิเนท และไม่เกิด การแบ่ง ส่วนในปริมาณมากไปยังวัฏภาคแอคเควียสที่ถูกแยกในเครื่อง แยกวัฏภาคDC60 (25/08/47) uses a quinone methide derivative such as 4-benzylidene-2,6-di-tert-butyl-cyclohexa-2,5- dienone to inhibit the polymerization of styrene monomer in the dehydrogenation portion of the system. The styrene monomer production inhibitor is exposed to the dehydrogenation outflow stream and does not undergo significant partitioning to the separated accelerating phase in the phase separator.
