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.

摘要:In a method of synthesizing a silicoaluminophosphate or aluminophosphate molecular sieve comprising a CHA framework-type material, a synthesis mixture is provided comprising a source of aluminum, a source of phosphorus, optionally a source of silicon and at least one organic template of formula (I):n n[R 1 R 2 R 3 R 4 N] + X −   (I)n nwherein each of R 1 , R 2 , R 3 , and R 4 is independently an acyclic alkyl group having at least one carbon atom, the total number of carbon atoms in said alkyl groups R 1 , R 2 , R 3 , and R 4 is greater than 8 but less than 16, and X − is an anion. The synthesis mixture can then be crystallized to produce the desired molecular sieve.

摘要:In a method of synthesizing a silicoaluminophosphate molecular sieve having 90%+ CHA framework type character, a reaction mixture is prepared comprising first combining a reactive source of aluminum with a reactive source of phosphorus to form a primary mixture that is aged. 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.

摘要:In a method of synthesizing a mostly CHA-type silicoaluminophosphate sieve, a reaction mixture comprises sources of water, silicon, aluminum, phosphorus, and a template. 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.

摘要:The synthesis of certain polyester diols (PEDs) is disclosed. This application also discloses the purification and polymerization kinetics of lipid based PEDs. Molecular weight and distribution controls were achieved by initial and induced stoichiometric imbalance and optimization of the purification protocol. Thermal degradation and thermal transition behavior of the PEDs were also investigated by TGA and DSC.
