I problemi con il nitroetano in Europa sono iniziati nel 2007, poi gradualmente tutti i Paesi hanno imposto restrizioni su questo prezioso reagente. Ora ci sono due strade: cercare fornitori in Paesi con una legislazione debole e un'industria chimica sviluppata, come ad esempio il Bangladesh, oppure sintetizzare autonomamente, con la metodologia che abbiamo proposto.

Cosa si può usare per sostituire o sintetizzare il nitroetano?

Try and figure out. Share us your research data. In theory, it's quite weak base and it would be not enough to eliminate -OH group.

has anyone done the microwave version of this synthesis, curious as to the outcome?

This is an effective method. I irradiate at maximum power in short time intervals so that the mixture does not have time to boil.

that is the key, stopping the irradiation just prior or as soon as you see 1 tiny bubble rise up, did this method with very good success, simple but very effective. would be very interested if there's other synths that can be done using the microwave??
