Please ask an expert to help solve this: detailed methods for purifying 1-bromonaphthalene! If using vacuum distillation! To what temperature should it be adjusted roughly, and what are the specific steps? It’s better to write in more detail! Thank you!
Check its physical properties, normal-pressure boiling point, reduced-pressure boiling point… then you’ll know; the temperature isn’t fixed – increase the temperature gradually until vaporization occurs
During the distillation process, yellow flocculent solids formed in the condenser; I’m not sure what’s causing this, 2# craig
