Analyses of Clusters of Water Dissolved in Tetradecane, Liquid Paraffin, and Polybutadiene by FT-IR Spectroscopy, and Effects of Coexisted Ions

Abstract

The state of water clusters of dissolved with distilled water (DW), hydrochrolic acid (WHCl), and potassium hydroxide (WKOH) in hydrocarbons such as n-Tetradecane (TD), Liquid paraffins (LPs), and Polybutadiene (PB) was analyzed by FT-IR spectroscopy at 20°C. The amount of water dissolved with DW in TD, LPs, and PB increased in the following order: TD<LPs<PB. In TD, LPs, and PB, the amount of water dissolved with DW, WHCl, and WKOH increased in the following order: DW<WKOH<WHCl. The number of clusters in TD, in LPs, and in PB increased in the following order: DW<WKOH<WHCl. The solubility of WHCl and WKOH in PB is incresed by the interaction between the double bond of PB and the coexised ions in the dissolved water.
