Claims Analysis
Total Claims: 22
Claim 1
Independent Claim
51 words
Process for the preparation of an organic amine complex of a metal halide, other than aluminum halide, said process comprising reacting a reactant mixture composed of the metal and an organic amine hydrohalide selected from a primary organic amine hydrohalide, a secondary organic amine hydrohalide, and a tertiary organic amine hydrohalide.
Claim 2
Dependent Claim
51 words
Process for the preparation of an organic amine complex of a metal halide, other than aluminum halide, said process comprising reacting a reactant mixture composed of the metal and an organic amine hydrohalide selected from a primary organic amine hydrohalide, a secondary organic amine hydrohalide, and a tertiary organic amine hydrohalide.
Claim 3
Dependent Claim
18 words
The process of claim 1 wherein the halide ions within the metal halide are chloride, bromide, or iodide.
Claim 4
Dependent Claim
26 words
