Abstract: The invention provides a process for production of mirtazapine as a convenient process for obtaining mirtazapine from a reaction mixture obtained by cyclization of 2-(4-methyl-2-phenylpiperazin-1-yl)pyridine-3-methanol with concentrated sulfuric acid, at high purity and in a form suitable for safe use as a drug. The production process for mirtazapine is characterized in that a reaction mixture obtained by cyclization of 2-(4-methyl-2-phenylpiperazin-1-yl)pyridine-3-methanol with concentrated sulfuric acid is diluted with water, the dilution is alkalinized in the presence of propanol, the mirtazapine is extracted with propanol and the mirtazapine is crystallized from the extract.

Abstract: Mixtures are provided of lithium salts with reducing agents for lithium evaporation. The mixtures may be particularly used in the manufacture of electroluminescent organic displays. Lithium dispensers based on the use of these mixtures are also provided.

Abstract: Methods for producing anhydrous mirtazapine crystals that are either (1) substantially free of lower alcohol insolubles or (2) substantially free of residual solvent and have an average particle diameter of from 10 to 50 &mgr;m, are provided, and the resulting anhydrous mirtazapine crystals produced thereby, which are useful in pharmaceuticals.

Abstract: A process for preparing a piperazine derivative represented by the formula (V): comprising reacting 1-methyl-3-phenylpiperazine with 2-chloro-3-cyanopyridine in an aprotic polar organic solvent in the presence of a base and an alkali metal halide. The piperazine derivative and its oxalate are compounds useful as preparation intermediates of mirtazapine.

Abstract: In a flat panel display containing a getter material, the getter material is activated during the sealing step, and is partially consumed, if the getter activation temperature is lower than the sealing temperature. On the other hand, a very small part of the getter material is activated if the getter activation temperature is higher than the sealing temperature.
