Claims (1)

5-20 절대기압 범위의 압력하의 첫번째 증류탑 내에서 증류하여 이소부탄을 포함한 상층류와 잔유성분들을 포함하는 저부류를 얻고, 잔류성분을 포함한 저부류를 3-10 절대기압 범위의 압력하의 둘째 증류탑내에서 증류하여 80-95%순도의 부텐-1 상층류와, 고비등 화합물, n-부탄 및 시스-와 트란스-부텐-2-를 포함한 저부류를 얻는 단계들로 구성된 중합급 부텐-1의 회수공정에 있어서, 둘째 증류탑으로부터의 상층류를 부타디엔과 아세틸렌 유도체의 선택적 수소화 단위공정에 주입하여 이 화합물들을 30-200ppm 범위 농도로 감소시키고 선택적 수소화 단위공정으로부터 발생된 생성류를 3-10 절대기압 범위의 압력에서 조작되는 증류탑에 주입하여 탑의 상단에 인접한 단으로부터 중합급 부텐-1을 수득함을 특징으로 하는 이소부텐으로부터 유리된 C4분율로부터 중합급 부텐-1의 회수공정.Distillation in the first distillation column under pressure in the range of 5-20 absolute pressure to obtain the upper stream containing isobutane and the lower stream containing residual components, and the lower stream containing residual components in the second distillation column under pressure in the 3-10 absolute pressure range. Recovery of polymerized butene-1 consisting of distilling in to obtain a butene-1 supernatant of 80-95% purity and a low class containing high boiling compound, n-butane and cis- and trans-butene-2- In the process, the supernatant from the second distillation column is injected into a selective hydrogenation unit of butadiene and acetylene derivatives to reduce these compounds to a concentration in the range of 30-200 ppm and the product stream from the selective hydrogenation unit process in the range of 3-10 absolute pressure. C 4 fraction freed from isobutene, characterized in that it is injected into a distillation column operated at pressure to obtain a polymeric grade butene-1 from a stage adjacent to the top of the column. Recovery process of terpolymer polymerization butene-1. ※ 참고사항 : 최초출원 내용에 의하여 공개하는 것임.※ Note: The disclosure is based on the initial application.
