摘要:
A method of creating solvent extraction reagent formulations that have high conductivity by combining (a) phenolic oxime extraction reagent(s) or other extraction reagent(s) in the organic phase of a solvent extraction circuit of a metal recovery operation, comprising combining the phenolic oxime extraction reagent(s) or other reagent(s) with one or more ketone, nitrile and/or amide compounds, or mixtures thereof, to create an extraction reagent formulation with a conductivity of at least 4,000 pS/m, measured according to the provisions of BS 5958 Part I, as well as a method of creating an organic phase that has a high conductivity, preferably a conductivity of at least 250 pS/m, comprising adding to that organic phase in an extraction circuit a phenolic oxime extraction reagent formulation with one or more ketoxime, aldoxime, mixtures thereof, or one or more other extraction reagents, and one or more ketone, nitrile, or amide compounds, or mixture thereof, and novel ketone, nitrile and amide compounds.

Compounds and methods for mitigating neurodegeneration, effecting neuroprotection and/or effecting cognition enhancement in a subject are described. Neurological or cognitive conditions are treated by administering to a subject an effective amount of a therapeutic compound comprising a nitrate ester, or a pharmaceutically acceptable salt or ester thereof.
摘要:
Nitrate esters and methods for mitigating neurodegeneration, affecting neuroprotection, affecting cognition enhancement, and/or preventing or mitigating tissue and/or cellular damage in a subject are described. Neurological or cognitive conditions, or damage mediated by free radicals are treated by administering to a subject an effective amount of a therapeutic compound comprising a nitrate ester, or a pharmaceutically acceptable salt thereof.

摘要:
A process for cyanating an aldehyde is provided. The process comprises reacting the aldehyde with: i) a cyanide source which does not comprise a Si—CN bond or a C—(C═O)—CN moiety; and ii) a substrate susceptible to nucleophilic attack not comprising a halogen leaving group; in the presence of a chiral catalyst. Preferably, the chiral catalyst is a chiral vanadium or titanium catalyst. The cyanide source is preferably an alkali metal cyanide and the substrate susceptible to nucleophilic attack not comprising a halogen leaving group is a carboxylic anhydride.
