摘要
利用时域反射技术(TDR)测量了不同摩尔比的四氢呋喃(THF)水溶液生成水合物前后的介电常数,并根据生成水合物前初始含水量和生成水合物结束后剩余水含量理论值建立了测量"THF水溶液+水合物"体系含水量的经验计算公式。随后,利用该公式计算出了THF水合物生成过程中水合物的含量,并建立了水合物含量与介电常数之间的关系式。此外,THF水溶液生成水合物过程中介电常数随时间非线性减小。
TDR was used to determine dielectric constant of THF aqueous solution with different THF/H2O mole ratios before and after THF hydrate formation.As a result,the empirical formula was built to measure the water content of the system of ＂THF aqueous solution ＋ THF hydrate＂.Then,the formula was applied to calculation of the content of THF hydrate produced by THF aqueous solution and to establishment on correlation between the content of hydrate and dielectric constant.In addition,the dielectric constant decreased during hydrate formation in THF aqueous solution.
