摘要： A process for producing oxidized organic chemical products such as propylene oxide from various organic chemical feedstocks utilizing as oxidant directly produced hydrogen peroxide (H2O2) intermediate oxidizing agent. The hydrogen peroxide intermediate is directly produced from hydrogen and oxygen feeds plus a suitable solvent in a first catalytic reaction step utilizing an active supported phase-controlled noble metal catalyst at reaction conditions of 0-100° C. temperature and 300-3,000 psig pressure. An organic chemical feedstock such as propylene together with the hydrogen peroxide intermediate and solvent solution are fed into a second catalytic reactor maintained at 0-150° C. temperature and 15-1,500 psig pressure and oxidized to produce a desired crude oxidized organic product such as propylene oxide, which is purified by distillation steps and recovered from the solvent solution.

摘要： Acetaldehyde may be effectively removed from a contaminated methanol stream using a distillation method wherein a solvent stream containing a relatively heavy polar compound such as water or propylene glycol is utilized as an extractive distillation solvent. Following the separation of the polar compound from the bottoms stream obtained by extractive distillation, the purified methanol may be recycled for use as a reaction solvent in an olefin epoxidation process.

摘要： Metal-containing colloids are manufactured by reacting a plurality of metal ions and a plurality of organic agent molecules to form metal complexes in a mixture having a pH greater than about 4.25. The metal complexes are reduced for at least 0.5 hour to form stable colloidal nanoparticles. The extended reduction time improves the stability of the colloidal particles as compared to shorter reduction times. The stability of the colloidal particles allows for colloids with higher concentrations of metal to be formed. The concentration of metal in the colloid is preferably at least about 150 ppm by weight.

摘要： The amount of high molecular weight impurity present in a polyether polyol produced by alkoxylation of an active hydrogen-containing initiator using an epoxide such as propylene oxide and a substantially amorphous highly active double metal cyanide complex catalyst may be advantageously lowered by having a non-protic Lewis acid present during the epoxide polymerization. The use of halides such as zinc chloride and aluminum chloride is especially effective for such purposes. In a preferred embodiment, minor amounts of water are also present during polymerization. The higher purity polyether polyols thereby produced are particularly useful in the preparation of slab and molded polyurethane foams, which tend to collapse or become excessively tight when elevated levels of high molecular tail are present in the polyether polyol.

摘要： Propylene oxide obtained by an epoxidation process which uses methanol as a solvent may be effectively treated to remove acetaldehyde by subjecting the crude epoxidation reaction product to fractional distillation. The methanol solvent is utilized during such distillation to lower the relative volatility of the acetaldehyde impurity, thereby making it possible to obtain a bottoms fraction containing substantially all the acetaldehyde. Purified propylene oxide having a reduced acetaldehyde concentration is removed as an overhead stream. Water may also be effectively separated from the propylene oxide using this procedure.

摘要： Supported catalysts include an inorganic solid support such as silica that is functionalized to have inorganic acid functional groups attached thereto. The functionalization of the support material is optimized by (i) limiting the amount of water present during the functionalization reaction, (ii) using a concentrated mineral acid or derivative thereof, and/or (iii) increasing the reaction temperature and/or reaction pressure. The acid-functionalized support material serves as a support for a metal nanoparticle catalyst. The nanocatalyst particles are preferably bonded to the support material through an organic molecule, oligomer, or polymer having functional groups that can bind to both the nanocatalyst particles and to the support material. The supported catalysts can advantageously be used for the direct synthesis of hydrogen peroxide from hydrogen and oxygen feed streams.

摘要： A process for catalytically directly producing hydrogen peroxide (H2O2) product from hydrogen and oxygen-containing feeds by contacting them with a supported noble metal phase-controlled catalyst and a suitable organic liquid solvent having a Solvent Selection Parameter (SSP) between 0.14×10−4 and 5.0×10−4 at reaction condition of 0-100° C. temperature and 100-3,000 psig pressure. Unconverted feed gas and organic liquid solvent solution are usually recovered and recycled back to the reactor along with any recovered catalyst. If desired, the hydrogen peroxide product can be fed together with an organic chemical feedstock such as propylene and with the organic liquid solvent solution into a second catalytic reaction step which oxidizes the feedstock to produce a desired crude oxidized organic product such as propylene oxide, which may be purified by distillation steps and recovered from the solvent solution.
