Is the current situation possible for recreaction in a lab?

I want to convert cellulose to another form (crystalline => amorphous). Cellulose requires a temperature of 320 °C and pressure of 25 MPa to become amorphous in water.(Is the pressure achievable in the lab?)

Is this doable in the lab and how should I begin on reproducing that situation (which tools would I need) ?

I'm guessing that a bunsen burner would produce high enough temperatures (but I'm not quite sure about the pressure)

EDIT to my question, following up the advice of bobthechemist...

Crystalline substance to amorphous - Other ways? You can convert crystalline cellulose to the amorphous, more reactive form by heating it to a temperature of around 320°C under a pressure of 25MPa.

But are there other, less extreme ways, to achieve that amorphous form of the compound? So because I can't achieve these high temperatures, how can I achieve it in another way?

• That kind of pressure can be achieved in commercial high pressure reactors as far as I know. So if you have access to such equipment and know how to handle it safely, this should be possible. – Mad Scientist Sep 3 '13 at 18:24
• and without being able to use high pressure reactors? would I stand a chance? – user2117 Sep 3 '13 at 18:25
• A pretty good chance at injuring yourself, I'd say. I wouldn't dare to try such pressures with any improvised equipment, you're very likely to just blow the whole thing up. – Mad Scientist Sep 3 '13 at 18:26
• ok - so there is no possibility what so ever to do that? – user2117 Sep 3 '13 at 18:28
• That's about 250 times atmospheric pressure. A quick back of the envelope calculation suggests that a 160 pound person standing on a block that is 0.5x0.5 cm could generate 25 MPa of pressure. You'd need to be a very good acrobat to do that over a bunsen burner. – bobthechemist Sep 3 '13 at 19:25
