硫醚和亚砜类有机物,是得到国际公认的新型高效金属萃取剂,对铀、钍等放射性元素,稀土元素和铂系元素等多种过渡金属都有良好的萃取作用。但过去我国未有产品供应。去年以来,开始有二正辛基硫醚及其氧化产物二正辛基亚砜的小批量生产,填补了这个空白。使用单位反映,二者的性能良好,但成本高,品种少,远远不能满足科研和生产的需要。此外,合成硫醚所采用的经典工艺路线,通常收率较低,因而导致成本提高。 Thioether and sulfoxide organic compounds, is internationally recognized as a new efficient metal extractant, uranium, thorium and other radioactive elements, rare earth elements and platinum series of transition metals such as a variety of good extraction. But in the past, there was no product supply in our country. Since last year, began to have two n-octyl sulfide and its oxidation products n-octyl sulfoxide small batch production, to fill this gap. The use of units reflect the good performance of the two, but the high cost, less variety, far from meeting the needs of scientific research and production. In addition, the classic route used in the synthesis of thioethers is generally lower yields, resulting in higher costs.
