Abstract: An oil-water mixture treatment device has a laminar separator and an electric field separator. The laminar separator has a coalescing tube with coalescing filler provided therein, a separating tube arranged above the coalescing tube, and a discharging tube arranged above the separating tube. The coalescing tube is connected to said separating tube by a first connecting tube group and the separating tube is connected to the discharging tube by a second connecting tube group. The oil-water mixture to be treated enters, after being treated in the coalescing tube, the separating tube through the first connecting tube group for laminar separation. The resulting oil phase enters the discharging tube through the second connecting tube group and then is discharged through an oil discharge pipeline, while the resulting water phase enters the electric field separator from a lower portion of the separating tube for a next stage of separation.

Abstract: An oil-water separation apparatus has a housing that contains at least one longitudinal plate member arranged in a longitudinal direction of the housing (10) and inclined relative to a horizontal direction. The longitudinal plate member forms at least one fluid channel in an inner chamber of the housing. A first guiding hole is provided on the longitudinal plate member or between the longitudinal plate member and an inner wall of the housing, and is in communication with the fluid channel. A second guiding hole is provided on the longitudinal plate member or between the longitudinal plate member and the inner wall of the housing, and is in communication with the fluid channel and is placed lower than the first guiding hole is positioned. A collection pipe is arranged at a longitudinal downstream end of the housing, and is in communication with the inner chamber of the housing.

Abstract: A process is claimed for the enantioselective epoxidation of ?,?-unsaturated ketones, in which a compound of the general formula I, is reacted with an oxidizing agent to form ?,?-epoxy ketones of the general formula II, in which R1, R2, R3 are as defined above. The ?,?-epoxy ketones of the general formula II can be obtained in good yields and outstanding enantioselectivities from ?,?-unsaturated ketones of the general formula I by epoxidation with hydrogen peroxide in the presence of a chiral catalyst, such as amino compounds and their acid addition salts.

Abstract: The invention relates to a method for producing chiral organic compounds by asymmetric catalysis, using ionic catalysts comprising a chiral catalyst anion. The claimed method is suitable for reactions which are carried out over cationic intermediate stages, such as iminium ions or acyl pyridinium ions. The invention enables the production of chiral compounds with high ee values, that until now could only be obtained by means of costly purification methods.
