I performed the synthesis using concentrated HBr, H2SO4 and pentanol. Weighed everything according to the instructions and refluxed for 3,5 hours, then distilled the mixture of water and bromopentane, stored the lower layer, rinsed with water, HCl, water, NaHCO3 solution, water and distilled. My thermometer showed a distillation temperature of 128°C, so it held on to the end of distillation. I guess it's a thermometer fault that's from China.
And as I mentioned, I think 1-bromopentane contains the alcohol, because I smell the "musty" smell of pentanol + smell of bromopentane.
