Sonic velocity in liquid primary normal alcohols

A method is proposedfor calculating sonic velocity in liquid n-alcohols. The method is based on the use of laws governing the behavior of these alcohols in a homologous series. The coefficients of the generalizing function are calculated in relation to the number of carbon atoms in the alcohol molecule, temperature, and pressure. It follows from sample calculations which are performed that the recommended method gives information on sonic velocity with an error no greater than the experimental error. It is shown that the method can be used to predict the given properties in the series of normal alcohols from $C_4$ to the higher homologs in the region of the liquid state within the investigated range of state parameters $(T = 303$–$453$ K and $P \le 100$ MPa$)$.
