| 20110190517 | Process for making titanium-MWW zeolite - Titanium-MWW zeolite is prepared by heating a gel formed from a titanium compound, a silicon source, a boron source, an MWW-templating agent, and water at a temperature in the range of 35° C. to 75° C. for a period of 8 to 30 hours to form a pre-crystallized gel, and heating the pre-crystallized gel to a temperature in the range of 160° C. to 190° C. for a period of 5 or more days to form the titanium-MWW zeolite. The zeolite, after it is contacted with an acid, is useful in olefin epoxidation with hydrogen peroxide. | 08-04-2011 |
| 20130165676 | Process For Producing Propylene Oxide - A continuous epoxidation process for the production of high purity propylene oxide by the reaction of propylene with an oxidant that is a per-acid, such as peracetic acid (PAA), in a reactive distillation (RD) column. The RD column provides excellent heat integration and temperature control, and the process has the advantage of lower investment cost for capital equipment. The process operates at mild temperatures and pressures. A ferric acetylacetonate homogeneous catalyst and/or stabilizer may be included as part of the PAA feed to the process to increase PAA conversion and selectivity to propylene oxide. A pre-reactor can be incorporated upsteam of the RD column to increase the residence time at lower temperatures to enhance productivity. | 06-27-2013 |

| 20140171666 | PROCESS FOR THE MANUFACTURE OF A 1,2-EPOXIDE AND A DEVICE FOR CARRYING OUT SAID PROCESS - Apparatus and processes are provided for forming epoxide compounds. In one embodiment, a process for the manufacture of an epoxide is provided including adding an oxidant, a water-soluble manganese complex and a terminal olefin to form a multiphasic reaction mixture, reacting the terminal olefin with the oxidant in the multiphasic reaction mixture having at least one organic phase in the presence of the water-soluble manganese complex, separating the reaction mixture into the at least one organic phase and an aqueous phase, and reusing at least part of the aqueous phase. The invention is also related to a device for performing the above process. | 06-19-2014 |
| 20150375200 | METHOD OF PREPARING EXPOXIDATION CATALYSTS - A method of preparing epoxidation catalysts is disclosed. The method comprises: (a) adding an inorganic siliceous solid to a column to produce a solid-filled column; (b) adding to the solid-filled column a solution comprising titanium tetrachloride and a hydrocarbon solvent to produce a titanium tetrachloride-impregnated solid; and (c) calcining the titanium tetrachloride-impregnated solid at a temperature from 500° C. to 1000° C. to produce the catalyst. The inorganic siliceous solid has a pore volume of at least 0.8 cm | 12-31-2015 |
