标题:Method for the synthesis of molecular sieves
发明人：STROHMAIER KARL G; VAUGHAN DAVID E W
权利人:EXXON MOBIL CHEM PATENTS INC
摘要:The present invention provides a method for the synthesis of MeAPO molecular sieves which includes the following steps: providing a source of alumina, a source of phosphorus, water, and a template suitable for forming a MeAPO molecular sieve; providing a source of metal (Me) including metal particles, the metal particles measuring, in their largest dimension, equal to or less than five nanometers; providing a water soluble organic solvent capable of solubilizing the source of metal; forming a synthesis mixture from the source of alumina, the source of phosphorus, the water, the template, the source of metal, and the solvent; and forming a MeAPO molecular sieve from the synthesis mixture.

标 题 :One pot synthesis of urea (meth)acrylates
发明人：BESTGEN SEBASTIAN; BEYER SILVIA
权利人:EVONIK OPERATIONS GMBH
摘要:A one-pot synthesis of polymerizable and acyclic urea (meth)acrylates, preferably mono(meth)acrylates, can be performed via in-situ synthesis of urea alcohols or amines followed by direct reaction with a (meth)acrylate reactive diluent. The urea alcohol/amine is obtained from isocyanates and alcohols, amines, or hydroxyamines. Subsequently, the reaction with the (meth)acrylate reactive diluent takes place and the urea (meth)acrylate is directly obtained either in solution with the reactive diluent, or as a pure material after removal of the reactive diluent.

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.
