SYNTHESIS AND EVALUATION OF NEW AND IMPROVED GYRO FLOTATION FLUIDS
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 HOCH2(CF2)5CF2H, HOC(CH3)2(CF2)5CF2H and HOCH2(CF2)7CF2H 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) 2P(O)OH ((CF3)2CHO)2P(O)OH and (C3F7CH2O)2P(O)OH. Heavy metal derivatives of these phosphates are all high melting solids. The four following fluorinated beta-diketones were also prepared: CF3C(O)CH2C(O)C3F7, CF3C(O)CH2C(O)C7F15, CH3C(O)CH2C(O)C3F7 and CH3C(O)CH2C(O)C7F15. The thorium derivative of CF3C(O) ch2C(O)C3F7, Th(C7HO2F10)4, 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.
