专利号:US-11958751-B2 优先权日:2022-06-27 标 题:Method of synthesizing materials integrating supernatant recycle 发明人:HODGKINS ROBERT P; KOSEOGLU OMER REFA 权利人:SAUDI ARABIAN OIL CO 摘要:Methods are disclosed for synthesizing materials, including an initial synthesis in the presence of WS-ODSO (which can include a pH-modified WS-ODSO composition, in certain embodiments a neutralized WS-ODSO composition), and one or more subsequent syntheses using supernatant (“mother liquorâ€?) from a previous synthesis of the same or different materials. The synthesized materials in the initial synthesis and in subsequent synthesis can be the same or different inorganic oxide materials including amorphous oxides, crystalline oxides or oxides of metals. The methods advantageously reduce the amount of utility water required for synthesizing a material and reduce the water waste, and reduce the DSO waste from a refinery and discharge into the environment. In certain embodiments the methods reduce the requirements to procure an alkaline reagent required for synthesizing materials. In certain embodiments, supernatant can be recycled over multiple synthesis batches of the same or different type of materia.
专利号:US-6096288-A 优先权日:1998-10-12 标 题 :Synthesis of the cubic mesoporous molecular sieve MCM-48 发明人:ROTH WIESLAW J 权利人:MOBIL OIL CORP 摘要:A method for synthesizing MCM-48 includes combining an inorganic silica reagent, an alkylammonium hydroxide and halide-containing surfactant to form a reaction mixture which is maintained under sufficient conditions to form a crystalline MCM-48 product. In a preferred embodiment, the organic silica reagent and the alkylammonium hydroxide are combined in the agueous medium to form a first reactions mixture and the halide-containing surfactant is then added to the first mixture so as to form a second reaction mixture which is then reacted to form the MCM-48 product. The crystalline MCM-48 material according to the invention can be functionalized by adding aluminum. The crystalline MCM-48 product produced by the process of this invention possesses an X-ray diffraction pattern indicative of a cubic unit cell with Ia3d symmetry.
专利号:US-5585252-A 优先权日:1988-08-30 标 题 :Enantio- and regioselective synthesis of organic compounds using enol esters as irreversible transacylation reagents 发明人:WONG CHI-HUEY; WANG YI-FONG; HENNEN WILIAM J 权利人:SEARLE & CO 摘要:A process for irreversible regio- and stereoselective enzyme catalyzed acylation of alcohols using enol esters as acylating reagents is disclosed. The present invention permits the selective modification of hydroxyl group(s) of chiral and meso alcohols, including sugars, organometallics, and glycosides. The enol freed upon transesterification rapidly tautomerizes to the corresponding volatile aldehyde or ketone thereby preventing the reverse reaction from occurring.

专利号:US-8921261-B2 优先权日:2012-04-10 标题 :Catalyst for synthesizing glycerol carbonate from glycerol, method for producing the catalyst and method for synthesizing glycerol carbonate from glycerol using the catalyst 发明人:LEE MAN SIG; BAEK JAE HO 权利人:KOREA INST OF IND TECHNOLOGY KITECH 摘要:Disclosed are a catalyst for synthesizing glycerol carbonate from glycerol and a method for producing the catalyst. The method includes adding an aqueous NaOH solution, an aqueous KOH solution, or a mixture of an aqueous NH 4 (OH) solution and an aqueous NaOH solution to an aqueous solution of a mixture of zinc nitrate and aluminum nitrate, aging the mixture, filtering and washing the aged mixture to obtain a solid, and calcining the solid under an oxygen, nitrogen or helium atmosphere. The use of the catalyst enables the synthesis of glycerol carbonate from glycerol and urea with high conversion rate, selectivity and yield. Further disclosed is a method for synthesizing glycerol carbonate from glycerol using the catalyst.
