Modifications to basic procedure

6 Modifications to basic procedure 1. Reactions at elevated temperatures 

When a reaction needs to be heated or when there is any possibility that it 

Reagents can be added through the 3-way tap, provided a syringe with a long needle is used, or as an alternative a flask with a side arm fitted with a septum can be used. Whilst the temperature of a reaction is changing the bubbler of the system should be checked to make sure there is a constant inert gas pressure. 

Slow addition of reagents and large scale work 

When slow addition of an air-sensitive reagent is required it is best to
