The Acetate Work


Dry distillation train


Equipment
B34 1 litre flask for the acetate and 1 B24 1 litre for the water trap
Two 1 litre doublenecked flasks
Water-cooled longish condensor
Basic still-head
End piece
Glass and plastic tubing
Hot-plate 450oC plus
Steel saucepan
Clean sand
Ground charcoal

Place your chosen acetate salts into the one litre B34 flask to no more than half full. Place on sand bed of 2 cm. in steel saucepan and pour rest of sand around up to the neck or 2/3 of flask for insulation and thermal shock prevention upon cooling.
Grease the joints and connect still head and condensor to end piece and double necked receiver.
The second neck is the outlet for any volatile vapors to be passed through into the second flask via a glass tube into a water trap.
After bubbling through the water any toxic fumes are passed through charcoal in the third flask. From there a plastic tube can be led to the outside.
After the train is sealed raise the heat incrementally every half hour until the liquifaction. Then the dry land appears and grows like leavened bread. The first distillate is the phlegm or water of crystallisation. (After this passes the flask can be emptied or replaced). It will then give up the ghost-like smoke that flows along the condensor and fills the receiver condensing into a pale golden water. As the heat is raised a reddish-brown oil ascends and perhaps a sublimate of volatile salt. When no more drops come over and no more bubbles pass through the water, turn down slowly. Disconnect water trap or vacuum will suck up water into the distillate.
The distillate is either circulated or rectified by fractional distillation.
