How to measure both primary and secondary hydrogen isotope effects in hydrogen abstraction from a substrate having two or more equivalent reactive hydrogen atoms

The Journal of Physical Chemistry, 1981
For a reaction of the type RH/sub n/ + B ..-->.. RH/sub n-1/ + BH, the substrate may be tracer labeled with tritium to give a mixture of RH/sub n/ and RH/sub n-1/T. Determination of the molar activity of BH after a low (< 5%) extent of reaction and of recovered RH/sub n/ after a known extent of reaction permits the precise determination of both the ...

10. Free movement of goods (II): quantitative restrictions and measures having equivalent effect

2018
This chapter reviews the law on the free movement of goods in the EU. It discusses the following: prohibition of quantitative restrictions and measures having equivalent effect; grounds of derogation under Article 36 of the TFEU; indistinctly applicable measures and mandatory requirements, Cassis de Dijon and developing the list of mandatory ...

ChemInform Abstract: HOW TO MEASURE BOTH PRIMARY AND SECONDARY HYDROGEN ISOTOPE EFFECTS IN HYDROGEN ABSTRACTION FROM A SUBSTRATE HAVING TWO OR MORE EQUIVALENT REACTIVE HYDROGEN ATOMS

Chemischer Informationsdienst, 1981
AbstractDurch partielle Tritiierung können beide Effekte ermittelt werden , wie am Beispiel der E2‐Reaktion von Ph‐CHT ‐ CHg ‐NMe3′ mit EtO′/EtOH bei 40°C gezeigt wird (prim.
