  • Patent number: 6090993
    Abstract: A process for preparing benzene containing less than 1 ppm (wt) dioxane from an aromatic stream containing benzene which is contaminated with dioxane, the process including providing an aromatic stream containing benzene which is contaminated with dioxane; subjecting the aromatic stream to liquid phase adsorption by contacting an adsorbent contained in at least one column, which adsorbent comprises at least one substance selected from the group consisting of molecular sieves and clay; and recovering benzene containing less than 1 ppm (wt) dioxane. Preferably, the liquid phase adsorption is carried out at a pressure ranging from atmospheric pressure to 20 kg/cm.sup.2 and at a temperature ranging from ambient temperature to 50.degree. C. Preferably, the molecular sieves have a pore size of 10 .ANG.. The process may further include regenerating the adsorbent by passing a flow of nitrogen gas through the adsorbent at a temperature ranging from 200 to 300.degree. C.

  • Patent number: 5854182
    Abstract: Magnesium borate overbased metallic detergent having magnesium borate uniformally dispersed in an extremely fine particle size is prepared by using magnesium alkoxide and boric acid. The process for preparation involves reacting neutral sulphonate of an alkaline earth metal with magnesium alkoxide and boric acid under anhydrous conditions in the presence of a dilution solvent followed by distillation to remove alcohol and part of dilution solvent therefrom. The borated mixture is then cooled, filtered to recover magnesium borated metal detergent. The magnesium borated metal detergent exhibited excellent cleaning and dispersing performance, very good hydrolytic and oxidation stability, good extreme pressure and antiwear properties. Such a detergent can advantageously be used in a hydrocarbon composition.
