标 题 :Synthesis of aluminophosphates and silicoaluminophosphates
发明人：CAO GUANG; SHAH MATU J
权利人:EXXONMOBIL CHEM PATENTS INC
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.

标题:Synthesis of 1,4-trans-polybutadiene using a lanthanide organic acid salt catalyst
发明人：LYNCH THOMAS J
权利人:BRIDGESTONE CORP
摘要:The invention provides a catalyst composition, comprising: (a) an organolithium compound; and, (b) an organic acid salt of lanthanide series element; wherein: (1) only components (a) and (b) are required to promote the synthesis of 1,4-trans-polybutadiene; (2) the ratio of component (a) to component (b) is selected to maximize formation of the trans structure of said 1,4-trans-polybutadiene; and, (3) components (a) and (b) are selected for enabling further diblock synthesis. The invention further contemplates a process for using the catalyst to synthesize 1,4-trans-polybutadiene and other polymers and copolymers having trans configuration in the conjugated diene monomer contributed units.

摘要:An objective of the present invention is to develop commercially viable methods for the synthesis of 5-[2-phenylsulfony)ethyl]-1H-indole of Formule (II), where R 1 and R 2 are same or different and each independently represent a hydrogen, fluorine, or di(lower alkyl)amino, acyl, or alkoxy carbonyl or chlorine atom, or a lower alkyl, lower alkoxy, nitro, cyano, aminolower alkylamine group Formula (II). Another objective of the present invention is to convert the product Formula (II) to Formula (I) in high yields, where R 1 and R 2 are same or different and each independently represent a hydrogen, fluorine, or di(lower alkyl)amino, acyl, or alkoxy carbonyl or chlorine atom, or a lower alkyl, lower alkoxy, nitro, cyano, aminolower alkylamine group Formula (I). One of the first processes attempted was by reacting the indole derivative of Formula (III) with aryl vinyl sulphones of Formula (V) as shown in Scheme-III. Another process attempted was by reacting the aniline derivative of Formula (VI) with aryl sulphones of Formula (VII) as shown in Scheme-III. Scheme IV.

标 题 :Process for the Synthesis of Amine Ethers
发明人：FREY MARKUS; BROENNIMANN VALERIE
权利人:CIBA GEIGY CORP
摘要:The present invention relates to novel processes for the preparation of a sterically hindered amine ether by reacting a corresponding sterically hindered amine oxide with a ketone or an aldehyde with at least one reactive H in the presence of a peroxydisulphate. Products obtained by this process may be hydrogenated. The compounds made by these processes are particularly effective in the stabilization of polymer compositions against harmful effects of light, oxygen and/or heat and as flame-retardants for polymers.
