标题 :Treatment of aromatic amines with gas mixtures derived from the oxidation of ammonia to effect diazotization/coupling
发明人：DETRICK JOHN KENT
权利人:DU PONT
摘要:1,3-Diaryl triazenes, e.g., 1,3-diphenyltriazene, intermediates in the synthesis of aromatic diamines, e.g., p-phenylenediamine, are prepared by catalytically oxidizing ammonia, and subsequently the resulting nitric oxide, with a gas comprising diluted molecular oxygen, e.g., air, so as to produce a gas mixture containing dilute NOx, i.e., NO2 preferably admixed with NO, x being (1 + n), wherein n is the NO2 fraction of the NOx; and contacting the gas mixture, preferably at a temperature in the range of about from 25 DEG to 350 DEG C., with excess primary aromatic monoamine, e.g., aniline, so as to result in a monoamine temperature in the range of about from 25 DEG to 90 DEG C., preferably 40 DEG to 60 DEG C., during contact. Highest yields of triazene are obtained when the x in NOx is about from 1.3 to 1.7, and the amount of NOx gas mixture contacted with the monoamine and the time of contact are such that at least about 60% by weight of the monoamine remains unconsumed. A gas mixture temperature just prior to gas contact with the liquid monoamine in the range of about from 110 DEG to 275 DEG C. is more preferred under certain circumstances.

摘要:The invention provides novel methods of synthesizing new monofunctional and/or multifunctional heterocyclic monomers and the formulation of new alloys of said monomers from base reactants via a continuous solvent-free, or alternatively in-solvent, one-step high shear reactor methodology designed to reduce the minor isomer formation and to eliminate the need for post-processing purification, as well as the ability to disperse reinforcements and additives while synthesizing such heterocyclic monomers and monomer alloys created and to the synthesis of related compositions.

标题 :System for the synthesis of spatially separated libraries of compounds and methods for the use thereof
发明人：READER JOHN C
权利人:MILLENNIUM PHARM INC
摘要:Featured is an apparatus useful for preparing combinatorial libraries of compounds in a parallel fashion so that the individual compounds of the library are spatially separate and the position of each compound of the library in the apparatus is known. Moreover, the apparatus is useful for the preparation of combinatorial libraries of compounds where the library is constructed from three or more building blocks, e.g., three, four, five, six or seven building blocks, resulting in a three, four, five, six or seven dimensional combinatorial library. Also featured are related methods for the preparation of three, four, five, six or seven dimensional combinatorial libraries of compounds using the apparatus of the present invention.
