20110082320 | CATALYTIC PROCESS FOR THE PREPARATION OF HYDROPEROXIDES OF ALKYLBENZENES BY AEROBIC OXIDATION UNDER MILD CONDITIONS - Process for the preparation of hydroperoxides of alkylbenzenes characterized by the fact that the alkylbenzene reacts with oxygen in the presence of a catalytic system consisting of an N-hydroxyimide associated with a peroxide activator having a peracid or dioxyrane structure, possibly generated in situ. | 04-07-2011 |
20110251436 | PROCESS FOR THE PRODUCTION OF ALKYLBENZENE HYDROPEROXIDES UNDER MILD CONDITIONS AND IN THE PRESENCE OF NEW CATALYTIC SYSTEMS - Process for the preparation of hydroperoxides of alkylbenzenes characterized by the fact that the alkylbenzene reacts with oxygen in the presence of a catalytic system which includes an N-hydroxyimide or an N-hydroxysulfamide and a polar solvent. | 10-13-2011 |
20120157718 | PROCESS FOR THE PREPARATION OF PHENOL AND CYCLOHEXANONE - Process for the preparation of phenol and cyclohexanone which comprises: | 06-21-2012 |
20130172624 | PROCESS FOR THE OXIDATION OF ALKYLAROMATIC HYDROCARBONS CATALYZED BY N-HYDROXY DERIVATIVES - Process for the oxidation of alkylaromatic hydrocarbons to hydroperoxide catalyzed by N-hydroxy derivatives in the presence of a solvent which includes recovering the catalyst from the oxidation mixture by the possible removal of the solvent by distillation and/or cooling of the oxidation mixture, with the consequent precipitation and filtration of the N-hydroxy-derivative catalyst, and adsorption with non-basic adsorbing solids for the substantially complete recovery of the catalyst. | 07-04-2013 |

20140192233 | METHOD AND APPARATUS FOR CREATING EXPOSURE EFFECTS USING AN OPTICAL IMAGE STABILIZING DEVICE - A primary exposure and an effects exposure of a scene are captured via a digital imaging sensor. During at least the effects exposure, the scene is caused to shift in a predetermined pattern relative to the digital imaging sensor via an image stabilizing device. The effects exposure and the primary exposure are combined to form a digital image. | 07-10-2014 |
