专利号:US-6835363-B1 优先权日:2003-08-06 标题:Synthesis of molecular sieves of CHA framework type 发明人:STROHMAIER KARL G 权利人:EXXONMOBIL CHEM PATENTS INC 摘要:The invention is directed to a method of synthesizing aluminophosphate and silicoaluminophosphate molecular sieves and in particular to the synthesis of aluminophosphate and silicoaluminophosphate molecular sieves using the synthesis templates that contain two dimethylamino moieties in combination with hydrogen fluoride. The use of this template in combination with hydrogen fluoride results in good quality SAPO molecular sieves of CHA framework type with low levels of silicon that are produced in relatively short crystallization times.
专利号:WO-9856796-A1 优先权日:1997-06-09 标题 :Delivery and scavenging agents for combinatorial synthesis 发明人:BOUSSIE THOMAS; HALL KEITH A; LAPOINTE ANNE M; MURPHY VINCE; POWERS TIMOTHY; BEEK JOHANNES A M VAN 权利人:SYMYX TECHNOLOGIES INC 摘要:Delivery and scavenging agents are provided for the combinatorial synthesis of organometallic compounds in a solution or suspension, where the agents are constructed from a solid support allowing for easy separation of unreacted reagents or unwanted materials from a synthesis reaction. Use of these solid supported agents also allows otherwise unfavorable reactions to be driven to completion by the use of large excesses of reactants and minimizes the chances for competing bimolecular side reactions in parallel or rapid serial synthesis.

A reactive source of silicon and a template for directing the formation of the molecular sieve can then be added to form a synthesis mixture. Crystallization is then induced in the synthesis mixture. Advantageously, (i) the source of silicon comprises an organosilicate, (ii) the source of phosphorus optionally comprises an organophosphate, and (iii) the crystallized silicoaluminophosphate molecular sieve has a crystal size distribution such that its average crystal size is not greater than 5 μm. The molecular sieve can then preferably be used in a hydrocarbon (oxygenates-to-olefins) conversion process.

In one aspect, the inorganic phosphorus and silicon sources are first combined to form a primary mixture that is aged. Then, the aluminum source is added, followed optionally by any organic phosphorus source, and then the template, to form the synthesis mixture. After heating at <10°C/hr to induce crystallization, in this aspect, both the crystallized sieve has an average crystal size ≤1.5μm and/or is recovered in a yield of ≥10.0wt%. In another aspect, when the synthesis mixture Si/Al2 ratio is <0.33, crystallization is induced. Advantageously, the sieve so crystallized has a template efficiency of ≥0.5 and/or is recovered in a yield of ≥10.0wt%. The molecular sieve from both aspects can be used in a hydrocarbon (oxygenates-to-olefins) conversion process.

The inventive compounds and libraries of compounds are reminiscent of natural products in that they contain one or more stereocenters, and a high density and diversity of functionality. In general, the inventive libraries are synthesized from diversifiable scaffold structures, which are synthesized from readily available or easily synthesizable template structures. In certain embodiments, the inventive compounds and libraries are generated from diversifiable scaffolds synthesized from a shikimic acid based epoxyol template. In other embodiments, the inventive compounds and libraries are generated from diversifiable scaffolds synthesized from the pyridine-based template isonicotinamide. The present invention also provides a novel ortho-nitrobenzyl photolinker and a method for its synthesis. Furthermore, the present invention provides methods and kits for determining one or more biological activities of members of the inventive libraries. Additionally, the present invention provides pharmaceutical compositions containing one or more library members.
