摘要: The present invention relates to a process for the production of an elemental material, comprising the step of reacting a halide of the elemental material with a reducing agent in solid form in a fluidized bed reactor at a reaction temperature which is below the melting temperature of the reducing agent. In a preferred embodiment of the present invention, the elemental material is titanium and the titanium is produced in powder form. The invention also relates to the production of alloys or intermetallics of the elemental materials.

摘要: A method of determining the content of polar-substituted alkyl nitrosoamines in a sample at levels as low as 20 nanograms in the presence of interfering substances such as nitrites and the like. After chromatographic separation, the nitrosoamine is reacted with reagent comprising hydrogen bromide, sulfanilamide, hydrochloric acid, surfactant and N-(1-naphthyl)ethylenediamine to give a colored product.
