专利号:US-2003130433-A1 优先权日:2001-10-30 标题 :Process for the production of graft polymers 发明人:WENZ ECKHARD; BUCHHOLZ VERA; EICHENAUER HERBERT; WOLF UDO; BORN RALF-JURGEN; JANSEN ULRICH; DIETZ WOLFGANG 摘要:A process of preparing a graft polymer (e.g., an ABS graft copolymer), which involves determining the concentration of at least one reaction component during the course of the reaction by means of Raman spectroscopy, is disclosed. The process, more particularly, comprises: (a) synthesizing the graft polymer from a reaction mixture comprising reactive components (e.g., monomers such as styrene and acrylonitrile, and a graft base); (b) analyzing the reaction mixture, at intervals, during the synthesis of the graft polymer, by means of Raman spectra; (c) recording the results of the Raman spectra analysis; (d) determining the concentration of at least one of said reactive components (e.g., styrene) by means of spectral evaluation of the recorded Raman spectra; and (e) terminating the synthesis reaction of the graft polymer when the concentration of at least one of the reactive components has reached a predetermined concentration value.

专利号:US-3773751-A 优先权日:1969-09-08 标 题:Synthesis of nitroaromatic-azophenols 发明人:BROOKS H 权利人:AMERICAN CYANAMID CO 摘要:A PROCESS FOR COUPLING AN O-NITOANILINE AND A WATER IMMISCIBLE PARA-ALKYLPHENOL IN AN AQUEOUS BASIC REACTION MEDIUM TO OBTAIN A NITROPHENYLAZOPHENOL. THE NOVEL FEATURES OF THE PROCESS ARE THE PRESENCE OF AN INERT WATER IMMISCIBLE SOLVENT AND THE USE OF A SPARINGLY SOLUBLE BASE. TYPICALLY, O-NITROANILINE AND P-T-OCTYLPHENOL ARE COUPLED IN A REACTION SYSTEM HAVING SEPARATE AQUEOUS AND NAPHTHA PHASES AND EXCESS CALCIUM HYDROXIDE, SOME OF WHICH IS IN THE UNDISSOLVED SOLID STATE. THE RESULTANT AZOPHENOLS ARE IN PURE FORM AND CAN BE USED TO PREPARE 2-(HYDROXYPHENYL)BENZOTRIAZOLES.

参考标题:Synthesis And Photophysics Of Dibenz[A,C]Phenazine Derivatives 作者:Leandro A. Estrada,Douglas C. Neckers |发布日期:2011.7.1 摘要:The Synthesis Of Dipolar Dibenz[a,C]Phenazine (Dbp) Derivatives Is Described. The Compounds Possess Little Electronic Communication Between Donor And Acceptor Units In The Ground State Regardless Of The Pattern Of Substitution. The Dipolar Derivatives Deactivate Mostly Via Electron Transfer (Et) Under Polar Conditions. Intersystem Crossing Is Likely To Compete For S1 Relaxation.
