5 unusual facts about chemical reaction


Catalysts and Catalysed Reactions

Each issue of the journal includes a selected collection of abstracts from recently published scientific articles covering the research areas of catalysed reactions and catalysts.

Symplectite

Symplectites may be formed by reaction between adjacent phases or to decomposition of a single phase.

The Ringing Bell

On November 8, 2007, the song "Name" was played at the beginning of the Season 4 Grey's Anatomy episode Physical Attraction, Chemical Reaction.

Transient kinetic isotope fractionation

Transient kinetic isotope effects (or fractionation) occur when the reaction leading to isotope fractionation does not follow pure first-order kinetics and therefore isotopic effects cannot be described with the classical equilibrium fractionation equations or with steady-state kinetic fractionation equations (also known as the Rayleigh equation).

The GEBIK and GEBIF equations are the most generalized approach to describe isotopic effects in any chemical, catalytic reaction and biochemical reactions because they can describe isotopic effects in equilibrium reactions, kinetic chemical reactions and kinetic biochemical reactions.


Erlenmeyer–Plöchl azlactone and amino-acid synthesis

The Erlenmeyer–Plöchl azlactone and amino acid synthesis, named after Friedrich Gustav Carl Emil Erlenmeyer who partly discovered the reaction, is a series of chemical reactions which transform glycine to various other amino acids via an oxazolone and an azlactone.

Hairpin ribozyme

It was first identified in the minus strand of the tobacco ringspot virus (TRSV) satellite RNA where it catalyzes self-cleavage and joining (ligation) reactions to process the products of rolling circle virus replication into linear and circular satellite RNA molecules.

Joule per mole

Physical quantities measured in J·mol−1 usually describe quantities of energy transferred during phase transformations or chemical reactions.

Swern oxidation

The Swern oxidation, named after Daniel Swern, is a chemical reaction whereby a primary or secondary alcohol is oxidized to an aldehyde or ketone using oxalyl chloride, dimethyl sulfoxide (DMSO) and an organic base, such as triethylamine.

Weidel's reaction

Weidel's reaction may refer to either a chemical reaction showing the presence of uric acid or xanthine bodies, or to a test (now considered obsolete) based on that reaction (invented by the Austrian chemist Hugo Weidel).
