Patent Number Title Of Patent Date Issued
5679850 Lithium diisapropylamide October 21, 1997
Lithium diorganoamide compositions are prepared in ethers with an ether to diorganoamide mole ratio of from about 2.0 to about 5.0. These compositions have enough thermal stability generally due to the addition of stabilizers that the decomposition rate for lithium diorganoamide is l
5219550 Production of low boron lithium carbonate from lithium-containing brine June 15, 1993
The present invention relates to a novel process for producing, from a lithium-containing brine, a low boron lithium carbonate compound. This compound is particularly useful for conversion to a highly pure lithium chloride for the production of lithium metal by electrolysis.
5196138 Preparation of mixed lithium amide reagents March 23, 1993
A method for preparing a poorly soluble lithium amides in greater concentration by preparing a mixture of lithium amides wherein one of said lithium amides is soluble and another lithium amide is less soluble, and the reagent compositions formed thereby.
5173209 Stable lithium cycloalkylimides December 22, 1992
A composition of at least one lithium cycloalkyl imide of the formula: ##STR1## wherein R and R' each represent a hydrogen or alkyl of 1 to 4 carbon atoms, and x and y are integers of 1 to 3.
5149457 Stable mixed lithium amide reagent compositions September 22, 1992
A method for preparing lithium amides in a monocyclic aromatic solvent and the reagent compositions formed thereby.
5068368 Stabilized lithium acetylide and reactions therewith November 26, 1991
A process for the preparation of ethynyl carbinols of the formula: ##STR1## wherein R" is hydrogen, a substituted or unsubstituted aliphatic or aromatic hydrocarbon, R'" is a substituted or unsubstituted aliphatic or aromatic hydrocarbon or R" and R'" together to the carbon atom to w
4980136 Production of lithium metal grade lithium chloride from lithium-containing brine December 25, 1990
The present invention relates to a novel process for producing, from a lithium-containing brine, a substantially pure lithium chloride product. This product is particularly useful for the production of lithium metal by electrolysis.
4867956 Active oxygen-rich compound and preparative method September 19, 1989
There is provided a novel active-oxygen rich lithium, boron, oxygen compound having the empirical formulaand a method for making the same.
