The design and development of structure parsing and naming system CAI of aliphatic hydrocarbon

Organic constituents in the sodium aluminate solution,which is the important intermediate material of the Bayer process,change evidently because of trace amount long fatty acid collector adsorbed onto bauxite concentrates entering into the Bayer process.

Variation of surface tension, viscosity and structure of sodium aluminate solution with long fatty acid Orgnic -PS floating collector was studied.

Separation of aromatic/aliphatic is important in petrochemical industry,and pervaporation is a potential alternative of the conventional energy-intensive technologies.

Quantitative structure-property relationship between molecular connectivity index (~mX~z) and boiling points of alicyclic and aliphatic hydrocarbons;

It is shown that tectonic stress is in favor of the chemistry environment transfer of hydrogen in coal, resulting in the decrease of aliphatic hydrocarbon and the increase of aromatic hydrocarbon in content, and accelerating the polycondensatio.

The experiment result showed that during the process of low temperature oxidation, the content of aromatic hydrocarbon and oxidized functional group is getting more and more along with the uprising of temperature, while the content of aliphatic hydrocarbon changed randomly.
