I performed aan acid catalysed haloform reaction in acetic acid to an acid. I need to evaporate acetic acid which I used as solvent and It is around 150 ml. What are the alternatives , I have a rotavap in lab but 150ml AA is too much for a rotavap I guess.

2$\begingroup$ Are you evapotating to dryness? Don't worry about alternatives - use the rotavap with a not too small wide-neck (NS29) flask. $\endgroup$ – Klaus-Dieter Warzecha Jun 2 '15 at 14:51

1$\begingroup$ Alternative: destillation followed by neutralisation/extraction. I used that to remove propionic acid (whose boiling point is a lot worse for rotavaps than acetic acid’s) from my porphyrin condensation. $\endgroup$ – Jan Jun 2 '15 at 15:19

1$\begingroup$ Rotavap is fine even until > 500 mL volume. $\endgroup$ – Jori Jun 2 '15 at 16:44
