After this time, the mixture stood at The above ingredients were put into 3 separate 100 ml., three neck flasks, each equipped with a condenser and ar- 10 ranged so that acetylene would bubble through each in series. 260-6065 42 Claims ABSTRACT OF THE DISCLOSURE This invention relates to organoboron compounds and to a method for their preparation. of benzene were allowed to react in a glass reactor. These usually occur at reduced flight speeds and extremely high altitudes. 6 7. 18. [8] Decaborane has been assessed for low energy ion implantation of boron in the manufacture of semiconductors. Trimethylamine was bubbled through the mixture to remove the decaborane, and the complex thus formed was filtered out into a weighed funnel. The purpose in doing this, as the art is well aware, is to provide proper burning TABLE VI Product Composition-Mass Spectrometrio Analysis Weight Percent Benzene Gas Sulfide, or Ether, Temp, Time, Evolu- Prod, Yield, CH, Example ml.

Because of their high chemical reactivity and heating values, the liquid products of this invention can be employed as fuels in ramjet engines and in afterburning and other auxiliary burning schemes for the turbojet and by pass or ducted type engines. It is soluble in cold water as well as a variety of non-polar and moderately polar solvents.[3]. 30. (0.058 mole).

The liquid products of this invention can also be employed as aircraft gas turbine fuels in admixture with the hydrocarbons presently being used, such as JP-4.

No. After this has been done, additional air is introduced into the combustor in order to cool sufficiently the products of combustion before 18 they enter the turbine so that they do not damage the turbine.

Its derivates were investigated as well, e.g. The residue was cooled, transferred to a 250 ml. 5. The solvents were distilled off at C. and /2 atmosphere pressure. In normal aircraft gas turbine practice it is customary to burn the fuel, under normal operating conditions, at overall fuel-air ratios by weight of approximately 0.012 to 0.020 across a combustion system when the fuel employed is a simple hydrocarbon, rather than a borohydrocarbon of the present invention. The degree of completeness of the reaction can be determined by the rate and quantity of hydrogen evolved, the rate at which solid products form and precipitate from solution, or by analysis of the reaction mixture. Example 6 A mixture of 2 g. (0.016 mole) of decarborane and 30 ml. It is toxic and volatile, with a foul smelling odor. There was no increase in pressure.

Decaborane has no significant applications, although the compound has often been investigated. Example 16 g. (0.041 mole) of decaborane, 3 ml. (0.49 mole) of tetrahydrofuran was heated overnight in an autoclave at 120 C. The tetrahydrofuran was distilled at reduced pressure, the residue was dissolved in pentane and treated with trimethylamine.
