  • Publication number: 20150315039
    Abstract: Disclosed herein is a method capable of economically treating water containing water-insoluble substance. The method for treating water containing water-insoluble substance, typified by produced water, using a porous material having functional groups on its surface and preferably made of an inorganic oxide includes: a first step of bringing an aqueous solution containing ions ion-exchangeable for the functional groups into contact with the surface to attach the ions to the surface; and a second step of allowing the water containing water-insoluble substance to pass through the porous material from the surface having the ions attached thereto to remove the water-insoluble substance from the water containing water-insoluble substance. The method may further include, after the first step but before the second step, the step of firing the porous material under a temperature condition of 300° C. to 500° C. for 1 to 5 hours.

  • Patent number: 4950824
    Abstract: A process for the production of 2,6-diisopropylnaphthalene is disclosed wherein an isopropylation reaction mixture containing isopropylated naphthalenes is subjected to transalkylation with a triisopropylnaphthalene-containing mixture to obtain a mixture containing mono-, di- and tri-isopropylnaphthalenes which is then separated into a first fraction containing monisopropylnaphthalenes, a second fraction containing diisopropylnaphthalenes and a third fraction containing triisopropylnaphthalenes. The first and third fractions are recycled to the above system, while the second fraction is subjected to separation treatments for the recovery of 2,6-diisopropylnaphthalene. The second fraction from which 2,6-diisopropylnaphthalene has been removed is subjected to transalkylation with naphthalene to obtain a monoisopropylnaphthalene-rich mixture which is to be fed to the isopropylation step.
