标题:半工业规模的硫酸亚铁焚烧废物稳定apc残留物.
摘要:已在半工业规模上针对三种类型的apc残留物证明了一种稳定的方法,用于从城市固体废物焚化(mswi)排放的空气污染控制(apc)残留物,包括将残留物与水和feso4混合,半干式(sd)apc残留物,粉煤灰(fa)以及来自湿法烟气清洁系统的fa与污泥(fas)混合.该过程分批处理,残留量为165-175 Kg.它产生的废水含盐量高,但重金属如cd,Cr和pb的含量低.稳定的残渣和未经处理的残留物已经过一系列浸出测试:分批浸出测试,Ph静态浸出测试,可用性测试和色谱柱测试.这些测试表明,稳定的残渣具有显着改善的浸出特性,尤其是对于pb而言,对于cd而言,铜和锌 铅的释放减少了250-36,000倍.

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.

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.
