Claims Analysis
Total Claims: 12
Claim 1
Independent Claim
88 words
A process for the production of hydrides of magnesium by means of hydrogen and transition metals as catalysts, characterized in that magnesium is reacted with hydrogen in the presence of a catalyst consisting of a halide of a metal of the fourth to eighth subgroup of the periodic system and an organomagnesium compound and/or a magnesium hydride, respectively, and optionally in the presence of a polycyclic aromatic compound or a tertiary amine, and optionally in the presence of a magnesium halide MgX 2 , wherein X=CI, Br, I.
Claim 2
Dependent Claim
88 words
A process for the production of hydrides of magnesium by means of hydrogen and transition metals as catalysts, characterized in that magnesium is reacted with hydrogen in the presence of a catalyst consisting of a halide of a metal of the fourth to eighth subgroup of the periodic system and an organomagnesium compound and/or a magnesium hydride, respectively, and optionally in the presence of a polycyclic aromatic compound or a tertiary amine, and optionally in the presence of a magnesium halide MgX 2 , wherein X=CI, Br, I.
Claim 3
Dependent Claim
23 words
A process according to claim 1, characterized in that the reaction is carried out in the presence of a solvent, preferably in tetrahydrofuran.
Claim 4
Dependent Claim
24 words
A process according to claims 1 and 2, characterized in that the reaction is carried out under a pressure from 1 to 300 bar.
Claim 5
Dependent Claim
23 words
A process according to claims 1 to 3, characterized in that the reaction is carried out at a temperature from 0°C to 200°C.
Claim 6
Dependent Claim
23 words
A process according to claims 1 to 4, characterized in that the ratio of Mg:transition metal is chosen from 10 4 to 10:1.
Claim 7
Dependent Claim
27 words
A process according to claims 1 to 5, characterized in that the ratio of transition metal:organomagnesium compound and/or magnesium hydride, respective, is chosen from 0.1:1 to 10:1.
Claim 8
Dependent Claim
25 words
A process according to claims 1 to 6, characterized in that halides of chromium, titanium, and/or iron, respectively, are used as the transition metal halides.
Claim 9
Dependent Claim
19 words
A process according to claims 1 to 6, characterized in that magnesium anthracene is used as the organomagnesium compound.
Claim 10
Dependent Claim
23 words
A process according to claims 1 to 8, characterized in that anthracene, tetracene, and/or benzanthracene, respectively, are used as the polycyclic aromatic compounds.
Claim 11
Dependent Claim
28 words
A process according to claims 1 to 9, characterized in that the tertiary amines NR 3 , wherein R=alkyl or cycloalkyl groups, are used as the tertiary amines.
Claim 12
Dependent Claim
36 words
A process according to claims 1 to 10, characterized in that in the reaction of the magnesium its halides MgX 2 , wherein X=CI, Br, I, are optionally added in the ratio of Mg:MgX 2 =1:1.
