60 of these messages are from Ghost when I first got here telling me go home nigger 😂
My black azz still here 😏
I don’t delete messages on NIS because of the habitual liars …💖
Still here still queer ..get used to it 💖😏

Chapter Eight
Phenylacetone via the Tube Furnace
The best way to produce phenylacetone on a large scale and continuous basis is by a catalyst bed
inside a tube furnace. This has several advantages over the other methods described in this book. Cheap
and very common acetic acid is used to react with phenylacetic acid instead of the expensive and more
exotic acetic anhydride and pyridine. Use of the tube furnace frees up the glassware for use in other
operations. The furnace requires very little attention while it is in operation, which allows the
underground chemist to spend his time turning the phenylacetone into methamphetamine. There is no
reason why this process cannot be used in small-scale production. It is just that its advantages really
come out when large amounts of phenylacetone must be produced.
In this process, a mixture of phenylacetic acid and glacial acetic acid is slowly dripped into a Pyrex
combustion tube which is tilled with pea-sized pumice stones covcred with a coating of either thorium
oxide or manganous oxide catalyst. This bed of catalyst is heated to a high temperature with a tube
furnace and the vapors of phenylacetic acid and acetic acid react on the surface of the catalyst to produce
ketones. Three reactions result.
The acid mixture is prepared so that there are three molecules of acetic acid for every molecule of
phenylacetic acid. This makes it much morc likely lhat the valuable phenylacetic acid will react with
acctic acid to produce phenylacetone rather than with another molecule of phenylacetic to produce the
useless dibenzyl ketone.

The vapors are kept moving i n the catalyst tube by a slow stream of nitrogen and eventually the
product comes out the far end of the catalyst tube. The vapors are then condensed and collected in a
flask.

The complete apparatus for doing this reaction is shown in Figure 23. The combustion tube is made of
Pyrex and is about one meter long. It is about 2 centimeters in internal diameter, with a male 24/40
ground glass joint on one end and a female 24/40 ground glass joint on the other end. I f the underground
chemist cannot buy the tube with the glass joints already on it, there are many places which will weld
these glass joints onto the tube. He can find such a place by asking around and checking the Yellow
Pages.
The tube furnace must be 70 centimeters in kngth. The only commercially available tube furnace that 1
know of is the Hoskins tube furnace. It is a tine furnace, but only 35 em in length. Two of these would
have to be run end-to-cnd to get the required 70 cm length. The cost, including a transformer for each of
the furnaces, would bc over $700. It is better and cheaper for the chemist to build his own tube furnace.
The tube furnace starts with a section of thinwall iron tubing about 75 cm long and 3 to 3.2 cm in
internal diameter. Thinwall iron tubing has a metal thickness of .024 inch. The outside of the tubing is
wrapped with asbestos cloth or asbestos paper to a thickness of about 2 millimeters. Asbestos cloth or
paper is available at hardware stores.
Fifty feet of 28 gauge AWG nichrome wire is wrapped around the central 70 em of the tube. The
windings are made fairly taut so that the wire sinks slightly into the asbestos paper. Each winding is
evenly spaced from the previous one, about y, cm apart. One winding must not be allowed to come into
contact with another, or there will be a short circuit.
The outside of the tubing is insulated with 6 or 7 layers of asbestos paper or cloth. This insulation is
held in place by using copper wire ligatures about 6 inches long, wrapped around the outside of the
insulation, and tied at the ends to make it tight.
