For one of our projects we are looking for a specialized company who develops and produces high vacuüm furnaces :
Vacuüm : 10-6 mbar or 10-4 Pa
Temp. : 1100°C
Dim. : 180 mm x 60 mm x 60 mm (l x w x h)

‘Franklin Roosevelt was showing that democracy was capable of taking care of its own; the New Deal was filling the vacuüm of faith which we had inherited from the cynicism and complacency of the twenties, and from the breadlines of the early thirtees.’
2002, Author Unknown, Jaarboek voor Middeleeuwse Geschiedenis 5, p64
Others took advantage of the power vacuüm: the bishop of Utrecht, the embryonic counties of Gelre, Kleef, and Zutphen, and the abbeys of Deutz and Abdinghof…
13,4 g dry LSA in 800 ml of DMF in a vacuüm flask @ 20°C, you add a solution of N,N-Carbonyldiimidazole in 250 ml of DMF. Stir for one half hour @ 20°C in the dark.
Add after that a solution of 4 g DEA in 50 ml of DMF.
Let stand for 2 hours @ 20°C and then 20 hours @ 5°C.
Evaporate in vacuüm to get the LSD.
Disolve in 2,5 L of 2% tartaric acid. Extract with Ether and discard Ether. Filter and basify with NH4OH and extract with a 9:1 ether:ethanol solution. Dry and evaporate in vacuüm to get LSD in 81% yield.
