More Information
Summary:Disclosed is a manufacturing method of high purity 1234yf from 245eb. Favorably, the manufacturing method of high purity 1234yf comprises the steps of: removing impurities existing in a tempered 245eb material; conducting dehydrofluorination of 245eb; and removing impurities existing in a final tempered product. The disclosed manufacturing method manufactures a 1224ye product favorably having approximately 500 ppm, and less than 50 ppm of 1225ye and/or trifluoropropene. 본 발명은 245eb로부터 고순도의 1234yf를 제조하기 위한 제조방법을 개시하며, 바람직하게는 245eb 조질의 재료에 존재하는 불순물의 제거, 245eb의 탈불화수소화, 및 최종 조질의 생성물에 존재하는 불순물의 제거를 포함한다. 개시된 제조방법은 바람직하게는 각각 약 500, 그리고 50ppm 미만의 양의 낮은 수준의 1225ye 및/또는 트리플루오로프로핀을 갖는 1234yf 생성물의 제조를 가능하게 한다.
