标题 :Synthesis of crystalline molecular sieves having the EUO framework type
发明人：MERTENS MACHTELD M W
权利人:EXXONMOBIL CHEMICAL PATENTS INC
摘要:In a process for the synthesis of a crystalline molecular sieve material having the EUO framework type, a synthesis mixture is provided suitable for the formation of an EUO framework type molecular sieve and comprising N,N,N,N′,N′,N′-hexamethylhexanediammonium, Q, cations and a colloidal suspension of seed crystals of an EUO framework type molecular sieve. The synthesis mixture is crystallized and an EUO framework type molecular sieve in the form individual crystals and/or aggregates of crystals having an average size, d 50 , as measured by laser scattering, of less than 15 μm is recovered from the synthesis mixture.

权利人:EXXONMOBIL CHEMICAL PATENTS INC
摘要:The present invention relates to the synthesis of succinimides, in particular to a method for the synthesis of a succinimide compound, comprising the step of reacting an alkyne, with carbon monoxide and ammonia or an amine, in the presence of an iron catalyst, wherein the reaction is carried out in an amine liquid phase and/or in the absence of an ether solvent. The succinimides may be reduced to quaternary ammonium cations which may be used as structure directing agents in the synthesis of molecular sieves.

标 题:Methods for high-yield synthesis of higher germanes and higher silanes

摘要:High-yield synthesis of higher germanes and higher silanes includes the hydrolysis of a germanium- or silicon-containing alloy with chemical formula AxByGe(Si), wherein A=Mg, Ca, Sr, Ba, Li, Na, K, Rb, Cs, and rare earth metals; B=Al, Si, Sn, Ga, Zn, Fe, Co, Ni, Cu, Ag; x=0-10, y=0-10. The hydrolysis reaction is promoted by an acidic substance such as boron oxide (B2O3), citric acid, hydrochloric acid (HCl), or sulfuric acid (H2SO4). The present invention provides an efficient method of drying higher germanes and higher silanes to prevent their further hydrolysis. Another synthetic process involves the reaction of germanium oxide, borohydride and boron oxide with water. Still another process comprises hydrolyzing the Si1-xGex alloy with a very dilute base solution. The methods enable production of higher germanes from a wide range of germanium-starting materials, including germanium byproducts, impure germanium compounds, and waste products generated in the plasma deposition of thin films containing germanium.

标 题 :Synthesis of porous crystalline materials in fluoride media
发明人：SCHMITT KIRK D; CASMER STEPHEN G
权利人:EXXONMOBIL RES & ENG CO
摘要:In a process for synthesizing a porous crystalline material, a mixture capable of forming said material is prepared wherein the mixture comprises sources of water, an oxide of a tetravalent element Y, preferably silicon, an oxide of a trivalent element X, wherein X is selected from the group consisting of aluminum, boron, gallium, iron, and indium, fluoride ions, and an organonitrogen cation RN capable of directing the synthesis of said material, wherein the molar ratio of fluoride ions to organonitrogen cations RN in said mixture is greater than 1.15 m but less than 2.5 m. The mixture is maintained under crystallization conditions until crystals of said material are formed and the resultant crystalline material is recovered.
