Abstract
Abstract A process and composition for the preservation of perishable biological specimens is used to embalm macroscopic lifeless biological specimens by immersion, infusion and infiltration techniques with a composition containing embalming agents that are compounds of the formula wherein R may be the same or different and is selected from the group consisting of H, CH₂OH, and -CH₂-, with the proviso that all of the R groups may not simultaneously be hydrogen and that when R is -CH₂-, both bonds may be attached to the same nitrogen atom or to two different nitrogen atoms, or may serve as a bridge to connect one additional unit having structure I.

Claims Analysis
Total Claims: 15
Claim 1
Independent Claim
112 words
In a method for embalming macroscopic specimens of the animal kingdom and humans wherein the specimen is treated with an embalming composition composed of an effective amount of an embalming agent and commercial additives, the improvement which comprises the embalming agent being wherein R may be the same or different and is selected from the group consisting of H, CH₂OH, and -CH₂-, with the proviso that all of the R groups may not simultaneously be hydrogen and that when R is -CH₂-, both bonds may be attached to the same nitrogen atom or to two different nitrogen atoms, or may serve as a bridge to connect one additional unit having structure I.
Claim 2
Dependent Claim
112 words
In a method for embalming macroscopic specimens of the animal kingdom and humans wherein the specimen is treated with an embalming composition composed of an effective amount of an embalming agent and commercial additives, the improvement which comprises the embalming agent being wherein R may be the same or different and is selected from the group consisting of H, CH₂OH, and -CH₂-, with the proviso that all of the R groups may not simultaneously be hydrogen and that when R is -CH₂-, both bonds may be attached to the same nitrogen atom or to two different nitrogen atoms, or may serve as a bridge to connect one additional unit having structure I.
