Abstract: A process for oxidizing an organic compound having at least one C-C double bond or a mixture of two or more thereof comprises the following steps:(I) preparing a hydroperoxide,(II) reacting an organic compound having at least one C-C double bond or a mixture of two or more thereof with the hydroperoxide prepared in step (I) in the presence of a zeolite catalyst,(III) regenerating the at least partially deactivated zeolite catalyst used in step (II), and(IV) conducting the reaction of step (II) using a zeolite catalyst containing the catalyst regenerated in step (III).

Abstract: PCT No. PCT/EP96/04504 Sec. 371 Date Apr. 21, 1998 Sec. 102(e) Date Apr. 21, 1998 PCT Filed Oct. 17, 1996 PCT Pub. No. WO97/15392 PCT Pub. Date May 1, 1997An improved process is provided for the recovery of catalyst components from oligomeric impurities which are formed during the industrial preparation of 2,5-dihydrofuran by the catalytic isomerization of vinyl oxirane followed by an essential separation of the oligomeric by-products which otherwise cause deactivation of the catalyst. The catalyst components consist essentially of (a) an onium iodide and (b) a Lewis acid selected from the group consisting of the chloride, bromide or iodide of the metals zinc, tin, cobalt and bismuth, preferably zinc, where the catalyst optionally includes a donor ligand. This separation is carried out by the steps of extracting the initial product mixture containing zinc, cobalt or bismuth halides as Lewis acids with hydrocarbons or chlorinated hydrocarbons containing from 5 to 14 carbon atoms in order to form two separate phases on standing, separating off the extraction solvent phase which contains the dissolved catalyst and then recovering the separated catalyst by distilling off the extraction solvent. The recovery of tin iodide requires the presence of a special onium halide component such as phosphazenium or phosphazanium halides, preferably the iodides, having a high molecular weight and especially those which contain from 16 to 72 carbon atoms while remaining soluble in the extracting agent.

Abstract: Vinyl polyether alcohols of the disclosure: Vinyl polyether alcohols of formula I I (R = C1-C25-alkyl, C2-C25-alkenyl or alkylaryl having a total of not more than 20 carbon atoms, A = 1,2-alkylene having from 2 to 4 carbon atoms and n = 1 to 20). These compounds serve as intermediates in the preparation of polyether sulfonates of formula III III (M = hydrogen, alkali metal or ammonium). The vinyl polyether alcohols of formula I are useful as surface-active compounds for inclusion in surface-active compositions.
