Analyses of clusters of water dissolved in tetradecane, liquid paraffin, and polybutadiene by FT-IR spectroscopy, and effects of coexisted ions

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 degrees 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.
