Os problemas com o nitroetano na Europa começaram em 2007 e, gradualmente, todos os países impuseram restrições a este valioso reagente. E agora há duas maneiras: procurar fornecedores em países onde a legislação é fraca, com uma indústria química desenvolvida, por exemplo, no Bangladesh, ou sintetizar de forma independente, a metodologia que propusemos.

O que é que pode ser utilizado para substituir ou sintetizar o 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??
