air-free

A properly designed, air-free system should continue to function normally for many years.

Where air-free requirements are not stringent, other techniques can be used.

The substance is air sensitive and its synthesis requires air-free techniques.

The range of methods used to work with air-sensitive compounds are known as air-free techniques.

The most straightforward type of air-free technique is the use of a glovebox.

The handling of oxophilic compounds often requires air-free techniques.

It is usually handled using air-free techniques.

These compounds react vigorously with water, and should be manipulated with air-free technique.

Samples are typically handled with air-free techniques.

For this reason, manipulations of ZrCl typically require air-free techniques.

The two most common types of air-free technique involve the use of a glovebox and a Schlenk line.

Stable carbenes are very reactive, and so the minimum amount of handling is desirable using air-free techniques.

The main drawback of vacuum transfer is that if there are any leaks, air will be drawn into the system and spoil the air-free environment.

It is a red solid that is pyrophoric in the air, and thus is typically handled with air-free techniques.

Air-free techniques are important so as to prevent this compound from reacting violently with oxygen and moisture in the air:

Due to the ease with which it reacts with O, the compound must be handled and stored using air-free techniques.

Under these conditions the ice freezes air-free and hence clear and stronger because there are no stresses built up in the ice.

In these situations, the HVA elements may not yet have been supplied with sufficient amounts of air-free oil.

Because of the sensitivity of potassium to water and air, the reactions are possible only in inert atmosphere, such as argon gas using air-free techniques.

TiCl and most of its complexes are typically handled under an air-free conditions to prevent reactions with oxygen and moisture.

Air-free techniques refer to a range of manipulations in the chemistry laboratory for the handling of compounds that are air-sensitive.

At the bench scale, chemists perform experiments on air-sensitive compounds using air-free techniques developed to handle them under inert gas.

Small-scale or quantitative preparations should be conducted under nitrogen or argon atmospheres, using air-free techniques.

In air-free water, the concentration of hydrogen, oxygen, and hydrogen peroxide reaches steady state at about 200 Gy of radiation.

However, provided rigorously dry, relatively non-acidic and air-free materials are used, stable carbenes are reasonably robust to handling per se.
