A process comprises contacting a product mixture with a base, optionally in the presence of a polyhydric alcohol, to produce a base-treated mixture and distilling the base-treated mixture in which the product mixture comprises an aromatic amine and a phenolic compound.

Separation of amine from a phenolic compound

A process that can be used for producing an alkali metal alcoholate such as sodium alcoholate or for removing a residual mixture containing alkali metal and alkaline earth metal from a vessel such as, for example, a tank car or storage tank used in manufacturing an alkali metal is disclosed. The process comprises contacting a mixture, which comprises an alkali metal and an alkaline earth metal, with an alcohol under a condition sufficient to produce an alkali metal alcoholate and alkaline earth metal alcoholate and, optionally, separating and recovering the alkali metal alcoholate.

Production of alcoholates

Process for preparing 2-(4'-thiazolyl)-benzimidazole (generic name: thiabendazole) by the acid-catalyzed condensation of o-phenylenediamine and 4-cyanothiazole using as a solvent polar organic compounds in which the reactants, catalysts and impurities are soluble, and the product, thiabendazole, is substantially insoluble.

Preparation of high purity thiabendazole

A photopolymerizable composition and a photoimaging element. The photopolymerizable composition is a cationically polymerizable organic composition and a photoinitiator which is a N-hydroxyamide, or N-hydroxyimide, sulfonate.

Photopolymerizable compositions containing N-hydroxyamide and

Process for formylating an alkyl-substituted benzene using carbon monoxide and hydrogen chloride, in the presence of aluminum chloride catalyst, in a reaction mixture which includes chlorobenzene as a solvent, and process for oxidizing an alkyl-substituted benzaldehyde using oxygen, in the presence of an autoxidation initiator, in a reaction mixture which includes cyclohexanone as a reductant.
