Claims
- 1. A substantially pure and crystalline compound of the formula: ##STR4## wherein M is an n-valent ion of Co, Ni, Cu or Zn; Y is n equivalents of an anion selected from the group consisting of fluoride, chloride, bromide, iodide, sulfate, nitrate perchlorate and acetate; each R independently is hydrogen or an alkyl radical of from 1 to 4 carbon atoms and n is 2 or 3, being the valence of M.
- 2. A process for preparing an aziridine-dimer chelate of the formula ##STR5## wherein M is an n-valent ion of Cr, Mn, Fe, Co, Ni, Cu or Zn; Y is n-equivalents of an inert anion; each R independently is hydrogen or an alkyl radical of from 1 to 4 carbon atoms; and n is 2 or 3, being the valence of M, said process comprising maintaining a solution of an aziridine-metal salt dissolved in a polar solvent at a temperature of from about 20.degree. to about 70.degree. C. for a time sufficient to convert the aziridine-metal salt to the aziridine-dimer chelate; said aziridine-metal salt corresponding to the formula ##STR6## wherein M, R, Y and n have the aforesaid meaning.
- 3. The compound of claim 1 wherein Y is chloride, bromide, nitrate, sulfate or acetate.
- 4. The compound of claim 1 wherein each R is hydrogen.
- 5. The process defined in claim 2 wherein the product is further reacted with NaOH to produce the free aziridine dimer.
- 6. The process defined in claim 5 wherein the solvent is an alcohol containing 1-4 carbon atoms, water, dimethyl sulfoxide, dimethylformamide, or a mixture of said solvents.
- 7. The process defined in claim 2 wherein M is Co, Ni, Cu or Zn.
- 8. The process defined in claim 7 wherein Y is fluoride, chloride, bromide, iodide, nitrate, sulfate, perchlorate or acetate.
- 9. The process defined in claim 8 wherein the reaction solvent is water, methyl alcohol, ethyl alcohol, dimethyl sulfoxide, or dimethylformamide, or a mixture of said solvents.
- 10. The process defined in claim 9 wherein said temperature is from 50.degree.-65.degree. C.
- 11. The compound of claim 4 wherein M is Cu, Y is chloride and n is 2.
- 12. The process defined in claim 2 wherein said temperature is 50.degree.-65.degree. C.
- 13. The process defined in claim 2 wherein the reaction solvent is water, an alcohol containing 1-4 carbon atoms, dimethylformamide, dimethylsulfoxide, or a mixture of said solvents.
- 14. The process defined in claim 13 wherein the process comprises the additional step of removing the solvent under reduced pressure to thereby precipitate the aziridine-dimer chelate as a crystalline solid.
- 15. The process defined in claim 10 wherein M is Cu, Y is chloride and n is 2.
- 16. The process defined in claim 15 wherein the process comprises the additional step of removing the solvent under reduced pressure to thereby precipitate the aziridine-dimer chelate as a crystalline solid.
