Tris 2,2,3,3,-tetrafluoropropoxy

Bis[morpholino] tellurium dichloride was also obtained from bis[tetrafluoropropoxy] tellurium dichloride or tris[tetrafluoropropoxy] tellurium chloride and iV-trimethylsilyl-morpholine3. 

The CSSX process utilizes a novel solvent made up of four components calix[4]arene-bis-(4-fer/-octylbenzo-crown-6) known as BOBCalixC6 as extractant a lipophilic fluorinated alcohol, l-(2,2,3,3-tetrafluoropropoxy)-3-(4-. ec-butylphenoxy)-2-propanol known as Cs-7SB, as diluent modifier tri- -octylamine as a suppressor of impurity effects and the isoparaffinic diluent Isopar L, a mixture of branched hydrocarbons with an average chain-length of 12 carbons. Figure 3 shows the composition of the solvent as currently optimized for the SWPF application at the SRS [37,49], The chemistry of the solvent is well understood, with regards to both its fundamental properties and its performance under process conditions. All of the components are commercially available, and efficient synthetic and purification procedures have been worked out [17,18,37], Thus, these key components may be obtained from multiple chemical suppliers capable of specialty synthesis. 

Bis[2,2,3,3-tetrafluoropropoxy] tellurium oxide was also obtained when the acetyl tellurium tris[fluoroalkoxide] was kept at 80° under 0.01 torr1.
