The density rho of 1-bromopropane, 1-bromobutane, 1-bromopentane, 1-bromohexane, 1-bromoheptane, 1-bromooctane, and 1-bromododecane have been measured within the temperature range from (243.15 to 423.15) K. The experimental results were used to calculate the isobaric thermal expansion coefficient alpha(p).
