What is claimed is: 1. A process for preparing halogenated alkanes whereby a haloalkane and a haloalkene are reacted in the presence of both an alkyl phosphate and iron wire to produce a halogenated alkane. 2. The process of claim 1 wherein the haloalkane comprises carbon tetrachloride, the haloalkene comprises vinyl chloride, and the halogenated alkane comprises 1,1,1,3,3-pentachloropropane. 3. The process of claim 2 wherein the carbon tetrachloride and the vinyl chloride are reacted in a reactor having a temperature of at least 105째 C. 4. The process of claim 2 wherein the carbon tetrachloride and the vinyl chloride are reacted in a reactor having a pressure of from about 5 to about 15 psig. 5. The process of claim 2 wherein the alkyl phosphate comprises tributyl phosphate. 6. The process of claim 2 further comprising converting the 1, 1,1,3,3-pentachloropropane to 1,1,1,3,3-pentafluoropropane. 7. The process of claim 1 wherein the reacting occurs prior to isolating the halogenated alkane. 8. The process of claim 1 wherein the haloalkane and the haloalkene are reacted in the presence of both the alkyl phosphate and the iron wire within a reactor, the reactor being provided a mixture comprising: the haloalkane; the haloalkene; and the alkyl phosphate. 9. The process of claim 8 wherein the mixture comprises at least two components, the first of the two components consisting of the haloalkane and the haloalkene, the second of the two components consisting of the alkyl phosphate, wherein the mixture comprises about 3% of the second component. 10. The process of claim 9 wherein the first component has a mole ratio of the haloalkane to the haloalkene of about 1.07:1. 11. The process of claim 8 wherein the mixture comprises at least two components, the first of the two components consisting of the haloalkane and the haloalkene, the second of the two components consisting of the alkyl phosphate, wherein the first component has a mole ratio of the haloalkane to the haloalkene of about 1.07:1. 12. The process of claim 1 wherein the haloalkane and the haloalkene are reacted in the presence of both the alkyl phosphate and the iron wire to produce the halogenated alkane within a reactor, further comprising removing at least a portion of the halogenated alkane from within the reactor, wherein the iron wire remains in the reactor during the removing. 13. The process of claim 1 wherein the elongated solid iron mass comprises iron wire.
