Abstract:

The objective of this research program is to produce liquids which have densities between 2.5 and 3.0 g.cc. for use as gyro flotation fluids. The work involved the synthesis of semi-inorganic compounds containing a heavy metal ion in combination with fluorocarbon anionic groups, i.e., fluorinated alkoxy, orthophosphate diesters, or beta-diketones. Hafnium and tantalum derivatives of HOCH2CF25CF2H, HOCCH32CF25CF2H and HOCH2CF27CF2H are viscous liquids with densities around 2.0 g.cc. Thallium dodecafluoroheptoxide, a low melting solid, has a density of 2.598 g.cc., whereas the density of unpurified thallium hexadecafluorononoxide is 2.48 g.cc. The thorium and lead fluoroalkoxides are solids as are all of the heavy metal derivatives of the shorter chain fluoroalcohols. Three hydrogen orthophosphate diesters were prepared C2F5CH2O 2POOH CF32CHO2POOH and C3F7CH2O2POOH. Heavy metal derivatives of these phosphates are all high melting solids. The four following fluorinated beta-diketones were also prepared CF3COCH2COC3F7, CF3COCH2COC7F15, CH3COCH2COC3F7 and CH3COCH2COC7F15. The thorium derivative of CF3CO ch2COC3F7, ThC7HO2F104, is a liquid whose density is 1.90 g.cc. Thallium complexes of all four of the above diketones are solids with relatively high melting points.
