DESCRIPTION
PROCESS FOR PRODUCING OLEFIN OXIDE
Cross-Reference to Related Applications
This application claims priority to and the benefit of U.S. Provisional Application No. 61/362,990, filed July 9, 2010, incorporated by reference here in its entirely.
Technical Field
The present invention relates to a process for producing an olefin oxide.
Background Art
Olefin oxides, such as propylene oxide, are important and versatile intermediates used in the production of a large variety of valuable consumer products such as polyurethane foams, polymers, alkylene glycol, cosmetics, food emulsifiers and as fumigants and insecticides.
Previous research on olefin epoxidation involved the use of Ag-based catalysts (Appl . Catal . A. Gen. 2001, 221, 73.), as well as silica supported Cu (J. Catal. 2005, 236, 401), various metal oxides (Appl. Catal. A. Gen. 2007, 316, 142), Au-based catalysts with ¾ as a co-reactant (Ind. & Eng. Chem. Res. 1995, 34, 2298, J. Catal. 1998, 178, 566; Appl. Catal. A.
Gen. 2000, 190, 43; Angew. Chem. Int. Ed. 2004, 43, 1546 ), titania based catalysts that deactivated quickly (Catal. Commun 2001, 1356; Catal. Commun. 2003, 4, 385), molten salts of metal nitrates (Appl . Catal. A. Gen. 2000, 196, 217), the use of 03 (Appl . Catal. A. Gen. 2000, 196, 217) and nitrous oxide (Ind. & Eng. Chem. Res. 1995, 34, 2298) as reactants. Although these developments are scientifically interesting, they have serious drawbacks, such as low PO selectivities and/or low propylene conversions, short catalyst lifetimes, the use of higher pressures or the use of costly co-reactants (Appl . Catal . A. Gen . 2007, 316, 142) .

Examples
In Example 1, data analysis was performed according to the following method:
A reaction gas was mixed with ethane (10 Nml/min) as an external standard, and then directly introduced in the TCD-GC equipped with a column of Gaskuropack 54 (2 m) . All products in the reaction gas were collected for 1 hour with double methanol traps connected in series and cooled with a dry-ice/methanol bath. The two methanol solutions were mixed together and added to anisole as an external standard, and then analyzed with two FID-GCs quipped with different columns, PoraBOND U (25 m) and PoraBOND Q (25 m) .
The detected products were propylene oxide (PO) , acetone (AT), COx (C02 and CO), propanal (PaL) , acrolein (AC)
Propylene conversions (XPR) were determined from the following :
XPR = {[ PO+AC+AT+PaL +C02/3]out/[C3H6]in} χ 100%; and PO selectivities (SP0) were then calculated using the following expression:
Spo = { [PO] / [PO+AC+AT+PaL +C02/3] } 100%
Each metal weight was determined from the amounts of the metal salts used for preparation of catalyst.
Example 1
A catalyst was prepared by a co-impregnation method. A predetermined weight (1.9 g) of amorphous silica powder (S1O2, Japan Aerosil, 380 m2/g) was added to an aqueous solution mixture containing 0.25 g of SnCl2 (Wako), 0.30 g of Cu (N03) 2 (Wako) and 0.10 g of NaCl (Wako) , followed by stirring it for 24 hours in the air to impregnate the support with the metal salts. The resulting material was then heated at 100°C until dried, and calcined at 500°C for 12 hours in air to give a catalyst.
The catalyst was evaluated by using a fixed-bed reactor. Filling a 1/2-inch OD reaction tube made of stainless steel with 1 mL of thus obtained catalyst, the reaction tube was supplied with 450 NmL/h of propylene, 900 NmL/h of air, and 990 NmL/h of a nitrogen gas to carry out the reaction at the reaction temperature of 200, 250 and 270°C under increased pressure (equivalent to 0.3 MPa in the absolute pressure) .
The result is shown in Table 1.

Example 2
The catalyst obtained in Example 1 (5.0 mg) was placed in a well of a reactor as mentioned in Angew. Chem. Int. Ed. 38 (1999) 2794, equipped with array microreactors, wells along each reactor channel and a passivated 200 micron ID capillary sampling probe within the reactor channel. The mixture gas consisting of 1 vol% propylene (C3H6) , 4 vol% 02, and 95 vol% He was fed to the well containing the catalyst, at a gas hourly space velocity (GHSV) of 20,000 h_1, at a reactor temperature of 250°C.
Gas sampling was accomplished by withdrawing reactor exit gases using the passivated 200 micron ID capillary sampling probe .
Data analysis for sample gases was conducted by an on-line Micro-Gas Chromatograph (Varian, CP-4900) equipped with a thermal conductivity detector (TCD) , PoraPLOT U (10M) and Molecular sieve 13X (10M) .
The detected products were propylene oxide (PO) , acetone
(AT) , acetaldehyde (AD) , COx (C02 and CO) , and propanal +
acrolein (PaL+AC) .
The propylene conversion, product selectivity, and yield (calculated as selectivity of product χ propylene conversion) of products were calculated on the basis of carbon balance.
Propylene conversions (XPR) were determined from the following :
XPR = { [PO+AC+AT+2AD/3+C02/3] 0ut / [C3H6]in} x 100%; and PO selectivities (SP0) were then calculated using the following expression:
SPO = { [ PO] / [PO+AC+AT+2AD/3+C02/3] } 100% Note: PaL+AC are reported together since the two compounds appear at the same retention time, although the PaL is typically only found in trace amounts.
The result is shown in Table 2.
