Distillation should be stopped before the flask reaches dryness to prevent the heating element from coming into contact with the dry residue, which can lead to overheating, thermal decomposition, or the risk of fire. Additionally, stopping before dryness helps avoid contamination of the distillate with impurities from the residue.

Precautions before distillation of an organic liquid?
Obtain approval from your laboratory instructor before starting a distillation. Make certain the apparatus has an opening...Use a fresh boiling chip each time a liquid is boiled to avoid bumping... Do not heat any distillation pot to dryness. Do not heat a closed apparatus because abrupt release of the increased pressure may propel reagents or pieces of glass... Also glassware that is superheated could crack. Before heating a flask, clamp the neck of the flask to support it in an elevated position to allow withdrawal of the heat source and rapid cooling... page 3-4.
How do you get the extracts of Sampaguita?
Sampaguita extracts can be obtained through steam distillation of the flowers. The flowers are usually soaked in water before the distillation process to release their aromatic compounds.
What is the name when magma reaches the surface?
Magma is liquid rock before it reaches the surface magma which reaches the surface is called lava.
What would happen if a steam distillation was stopped by turning off steam valve before opening the screw clamp on adapter trap?
If the steam valve is turned off before opening the screw clamp on the adapter trap during a steam distillation, pressure could build up in the system due to the trapped steam. This could potentially lead to a sudden release of pressure when the clamp is opened, causing the possibility of hot steam and boiling liquid being forcefully expelled from the system, posing a safety risk to the operator. It is important to follow proper procedures and safety protocols when conducting steam distillation to prevent accidents.
