摘要
Abstract
Effects of different modifiers on phase change temperature,volumetric contraction rate and melting time of n-hexadecane were investigated. The results show that the four modifiers of n-octane,n-nonane, n-heptane and para-xylene can adjust the phase change temperature of n-hexadecane. The volumetric contraction rate of n-hexadecane decreases sharply by n-nonane,n-heptane and para-xylene,while it varied a little by n-octane. The phase change temperature of n-hexadecane reaches 13.3 ℃ and the volumetric contraction rate of the n-hexadecane is 9.6% with 5% of n-octane. The melting times of n-hexadecane reduce 15%-59% at different temperature conditions with the increase of n-octane mass fraction. It can be concluded that n-octane is an effective modifier adjusting the phase change temperature and reducing the melting time of n-hexadecane,and has slight effect on the volumetric contraction rate of n-hexadecane.关键词
