An automatic analytical apparatus in which a series of operations ranging from the sampling into a treating receptacle, pretreatment, analysis and discharge of a fluid sample to the preparation for the next analysis are repeated automatically in order, wherein the time-dependent variation of the composition is traced successively. This permits the presence of the composition variation or the course of the composition variation to be confirmed or the composition variation to be controlled, automatically.

Method and apparatus for automatic analysis of fluid composition

A process for producing selectively o-alkylated phenols wherein an anisole having at least one ortho positioned hydrogen atom is contacted with a mixed oxide catalyst in the vapor phase.

Process for producing ortho-alkylated phenols from anisoles

A process for the production of alkyl phenols having at least one o-alkyl radical comprising catalytically reacting a phenolic compound having at least one o-positioned hydrogen atom with an alcohol in the vapor phase in the presence of a manganese oxide containing catalyst modified with a compound of at least one of the alkali metals.
