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 present invention is directed at mono-, di- or polyquaternary ammonium compounds of the formula (I) wherein x is 1 to 50, and F can be the same or different and is represented by the general formula (II) wherein at least one of the optionally substituted and optionally functional-group-containing hydrocarbon radicals R 1 , R 2 , R 3 , R 4 or R 5 contains at least one estolide moiety comprising two or more ester or amide moieties. The invention also relates to a process for the synthesis of such compounds, the use of the compounds in cosmetic formulations for skin and hair care, cosmetic compositions for the treatment of fibers, and compositions containing one or more of the compounds for the treatment of hair.

摘要:In a method of synthesizing a silicoaluminophosphate molecular sieve having 90+% CHA framework-type character, a reaction mixture is prepared comprising sources of water, silicon, aluminum, and phosphorus, as well as an organic template. In one aspect, the reaction mixture is heated at more than 10° C./hour to a crystallization temperature and is retained at the crystallization temperature or within the crystallization temperature range for a crystallization time from 16 hours to 350 hours to produce the silicoaluminophosphate molecular sieve. In another aspect, the reaction mixture is heated at less than 10° C./hour to a crystallization temperature from about 150° C. to about 225° C. and is then retained there for less than 10 hours to produce the silicoaluminophosphate molecular sieve. The molecular sieve can then be recovered from the reaction mixture and, preferably, used in a hydrocarbon conversion process, such as oxygenates to olefins.
