Miscibility print that page


In organic compounds , the weight percent of hydrocarbon chain often determines the compound's miscibility with water. For example, among the alcohols , ethanol has two carbon atoms and is miscible with water, whereas octanol with a C 8 H 17 substituent is not. Octanol's immiscibility

Azeotrope print that page

An azeotrope ( / ə ˈ z i . ə t r oʊ p / ə- ZEE -ə-trope ) is a mixture of two or more liquids in such a ratio that its composition cannot be changed by simple distillation . [ 1 ] This occurs because, when an azeotrope is boiled, the resulting vapor has the same ratio of constituents | 2011/5/3 8:46:33



Hydrotropy is a method of increasing the solubility of a substance or solute. Hydrotropy is the term originally put forward by Carl Neuberg [ 1 ] to describe the increase in the solubility of a solute by the addition of fairly high concentrations of alkali metal salts of various organic acids

Aerogel print that page


Aerogel was first created by Samuel Stephens Kistler in 1931, as a result of a bet with Charles Learned over who could replace the liquid in 'jellies' with gas without causing shrinkage. [ 3 ] [ 4 ] Aerogels are produced by extracting the liquid component of a gel through supercritical drying

Solvent print that page

uniformly distributed at a molecular level and no residue remains. The mixing is referred to as miscibility , whereas the ability to dissolve one compound into another is known as solubility . However, in addition to mixing, both substances in the solution interact with each other. When something | 2011/9/25 21:52:06

Lower critical solution temperature print that page

The word lower indicates that the LCST is a lower bound to a temperature interval of partial miscibility , or miscibility for certain compositions only. The phase behavior of polymer solutions is an important property involved in the development and design of most polymer-related processes | 2011/4/29 17:23:16
