Quality Analysis Of Sulfolane And Research And Development Of New Technological

The sulfolane is one of the organic sulphur solvents. It is used to the fields of aromatics extraction, gas purification and solution polymerization etc. At present, the color of most sulfolane is instable in civil market, especially in the condition of lighting and heating. Its color easy changes from the light yellow to the heavy brown or black dark brown, that effect the application and development of the sufolane. In this article, through the quality complete analysis to some sulfolane in the civil market, and use the color stability experiment to study the factors that influence on the sulfolane color stability such as inhibitor, stabilizer etc. At the same time, after thorough study the production process the conclusion is that the sulfolane easy to translate its color is not itself nature, but the instability impurities in sulfolane influence on its color stability. So using the organolite and activated charcoal to adsorption the impurities, then get the sulfolane is colorless and good thermal and light stability.
