Intensive Column Apparatus for Chemical Reactions

A fully automatic apparatus for chemical reactions on the laboratory scale

Introduction The apparatus described here is designed to automatically perform common chemical reactions on some tens to hundreds of grams of reactants. Its principal application is the necessary optimization of parameters when going from the research-laboratory scale to the pilot plant in fine organic chemistry, an operation which requires numerous repetitive assays [1 and 2]. It is also usefu...

International chemical identifier for chemical reactions

An open-access software for creating a unique, text-based identifier for reactions (RInChI) was developed by the Goodman group at the University of Cambridge, based on the IUPAC International Chemical Identifier (InChI) standard. RInChIs describe the substances (reactants, products, reagents and solvents) participating in a reaction with their respective InChIs. The structure of RInChIs is anal...

Chemical salt reactions as algebraic hyperstructures

A salt metathesis reaction is a chemical process involving the exchange of bonds between two reacting chemical species, which results in the creation of products with similar or identical bonding affiliations. Hyperstructure theory is studied from the theoretical point of view and for its applications. In this paper, we provide some examples of hyperstructures associated with salt m...

An apparatus for the study of fast precipitation reactions

An apparatus is described for the measurement of the rates of fast precipitation reactions. It consists of a T-tube, where reactants are added to the arms of the T, mixed rapidly at the junction, and the rates of disappearance of reactants or appearance of products are measured along the stem of the T. The geometry of the system results in a steady state being established in the apparatus, enab...
