实验步骤: 11-Bromoundecanoic acid (400 g) was added to thionyl chloride (600 ml) and the solution heated at 80° for 0.5 hour. The thionyl chloride was distilled off and the dark oily residue distilled in vacuo to give 11-bromoundecanoyl chloride, b.p. 144°, 0.7 mm Hg, (346.8 g, 81%). the solution heated at 80° for 0.5 hour The thionyl chloride was distilled off the dark oily residue distilled in vacuo

实验步骤: 55 g (0.20 moles) of recrystallised 11-bromo undecanoic acid were refluxed with 48 g (0.4 moles) of thionyl chloride for 3 hours. Excess thionyl chloride was then removed by vacuum distillation at 10-14 mm Hg pressure. The crude acid chloride remaining was distilled under higher vacuum (0.1 mm Hg) to give 50 g (0.18 moles) of pure 11-bromo undecanoyl chloride. Excess thionyl chloride was then removed by vacuum distillation at 10-14 mm Hg pressure The crude acid chloride remaining was distilled under higher vacuum (0.1 mm Hg)
