摘要:The invention is directed to a method of synthesising silicoaluminophosphate and aluminophosphate molecular sieves using synthesis templates that contain at least one template of general formula R 1 R 2 N—R 3 , wherein R 1 and R 2 are independently selected from the group consisting of alkyl groups having from 1 to 3 carbon atoms and hydroxyalkyl groups having from 1 to 3 carbon atoms; R 3 is selected from the group consisting of 4- to 8-membered cycloalkyl groups, optionally substituted by 1 to 3 alkyl groups having from 1 to 3 carbon atoms, and 4- to 8-membered heterocyclic groups having from 1 to 3 heteroatoms, said heterocyclic groups being optionally substituted by 1 to 3 alkyl groups having from 1 to 3 carbon atoms and the heteroatoms in said heterocyclic groups being selected from the group consisting of O, N, and S. In particular, the present invention relates to the synthesis of silicoaluminophosphate molecular sieves of the CHA framework type having a low silicon to aluminium atomic ratio.

摘要:In a method of synthesizing an aluminophosphate or metalloaluminophosphate molecular sieve, a synthesis mixture is provided comprising water, a source of aluminum, a source of phosphorus, optionally a source of a metal other than aluminum, a tertiary amine, and an alkylating agent capable of reacting with said tertiary amine to form a quaternary ammonium compound capable of directing the synthesis of said molecular sieve. The synthesis mixture is maintained under conditions sufficient to cause the alkylating agent to react with the tertiary amine to produce the quaternary ammonium compound and to induce crystallization of the molecular sieve.

标 题:One-pot synthesis of squaramides
发明人：MÃ?RQUEZ LÓPEZ MARÃ?A EUGENIA; ALEGRE REQUENA JUAN VICENTE; PÉREZ HERRERA RAQUEL
权利人:UNIV ZARAGOZA; CONSEJO SUPERIOR INVESTIGACION
摘要:The present invention refers to the first one-pot synthesis of squaramides. The one-pot synthesis of squaramides described herein is an easy and straightforward procedure to obtain squaramide derivatives which saves energy, avoids time consuming purification steps, reduces costs and provides better yields as compared with those squaramides obtained through the traditional 'stop-and-go' approach. Moreover, the authors of the present invention herein demonstrate the efficiency of this one-pot process with the synthesis of three biologically active structures, improving in most of the cases the results of the previous stepwise syntheses.
