To understand this, we would need to see what type of interaction sulfur and water undergo respectively. This battery shows excellent capacity and cycle life characteristics. Because xylene is heavier than air, it can reside in pockets near the ground. The purpose of the work was to obtain sufficient sulfur-solubility data in sour gas to develop a widely applicable predictive model of sulfur solubility vs. sour-gas conditions. In one large-scale application, para-xylene is converted to terephthalic acid. Alcohol, however, is not miscible with paraffin (something that is miscible can mix well with another substance). It is widely used in several industries as well as in dental and medical arenas. Search 205,780,047 papers from all fields of science. The much higher solubility of PPG versus PEG is due primarily to steric hindrance from the methyl branch, which weakens segment-segment interactions, and to a lesser extent to the stronger hydrogen bond donor strength of a primary (in the case of PEG) versus a secondary (in the case of PPG) alcohol terminal group. 2 SOLUBILITY OF WATER (2) IN O-XYLENE (1) The available solubility values for water in o-xylene are listed in Table 3.
