摘要： Titanovanadosilicalites have been found to be very selective, active catalysts in the epoxidation of olefins by peroxides. Dilute hydrogen peroxide suffices to afford high yields of the epoxide. Vanadium incorporation at levels of Si:V in the range 100-2500 effectively changes the characteristics of the titanosilicalite into which it is incorporated to give near quantitative conversion of propylene at selectivities greater than 90%.

摘要： A new family of crystalline microporous metallophosphates designated AlPO-57 has been synthesized. These metallophosphates are represented by the empirical formula R+rMmn+EPxSiyOz where R is an organoammonium cation such as the DEDMA+, M is a divalent framework metal such as an alkaline earth or transition metal, and E is a framework element such as aluminum or gallium. The microporous AlPO-57 compositions are characterized by a new unique ABC-6 net structure and have catalytic properties for carrying out various hydrocarbon conversion processes and separation properties for separating at least one component.

摘要： An apparatus and process for forming an array of powder samples arranged in predefined locations where all samples have a flat surface in a common plane has been developed. A monolithic block having a main support section having at least N perforations from a first surface of the main support through a second surface of the main support in predefined locations, where N is the number of samples in the array is provided. The monolithic block also has a flat support section covering the perforations of the main support section. All N samples are loaded simultaneously with sample X in perforation X of the main support where X is an integer from 1 to N. A flat surface of each sample where the flat surfaces are a common plane is formed by forcing the samples within the perforations against the flat support. The samples are retained in position within the perforations against the flat support, and are made ready for analysis since the flat surfaces of the samples are in predefined locations and are all in a common plane.

摘要： A method for rapidly screening multiple X-ray powder diffraction patterns, such as those generated through combinatorial chemistry, has been developed. The method is directed toward measuring X-ray powder diffraction patterns of a set of samples, factoring the patterns using a suitable statistical technique into a small number of discrete components or factors, determining the scores corresponding to the factors for each X-ray powder diffraction pattern, and plotting the scores. The graphs of the scores are then inspected for clusters, trends, or outliers, which may represent new material or, perhaps, faulty data.

摘要： For the removal of trace quantities of iodine-containing contaminants from corrosive liquid feed streams, an alternative with distinct advantages over the prior art is provided. The treatment method involves the use of a crystalline manganese phosphate which has been cation-exchanged with an iodine-reactive metal. This inorganic adsorbent may be used in unbound form, or it can bound with a substantially insoluble porous inorganic refractory metal oxide binder. A reactivation technique for this material is also presented.

摘要： A new family of crystalline manganese phosphate compositions has been prepared. These compositions have an extended network which network can be a one-, two-, or three-dimensional network. The composition has an empirical formula of:(A.sup.3+).sub.v (Mn.sup.b+)(M.sup.c+).sub.x P.sub.y O.sub.zwhere A is a structure directing agent such as an alkali metal, M is a metal such as Al, Fe.sup.3+ and "b" is the average manganese oxidation state and varies from greater than 2.0 to a maximum of 3.0. These compositions can be used as adsorbents and as catalysts in the oxidation of hydrocarbons.

摘要： A new family of crystalline molecular sieves have been synthesized. These compositions have a microporous structure of at least ZrO.sub.3 octahedral units and SiO.sub.2 tetrahedral units. Optionally, the molecular sieves contain M metals such as titanium or tin. These novel molecular sieves are prepared hydrothermally from a reaction mixture composed of reactive sources of the components.
