Caro João, a temperatura é uma variável que deve ser levada em consideração 
uma vez que a cinética da reacção varia com a temperatura, ou seja, maior 
temperatura significa menor tempo de reacção. No entanto, num reactor à 
pressão atmosférica não se deverá ultrapassar os 60ºC pois  a temperatura de 
ebulição do metanol é cerca de 63ºC.

Boa sorte e disponha sempre
