摘要： Provided is a process for preparing 2H-benzotriazole UV absorbers containing a perfluoroalkyl moiety at the 5-position of the benzo ring, for example a trifluoromethyl group, which involves diazotizing the perfluoroalkyl substituted o-nitroaniline using concentrated sulfuric acid plus sodium nitrite or nitrosylsulfuric acid to form the corresponding monoazobenzene intermediate via the diazonium salt intermediate which is reduced to the corresponding 5-perfluoroalkyl substituted 2H-benzotriazole UV absorber compound by conventional reduction means. Also provided is a novel one-pot, multiphase reaction for the preparation of 2(2-nitrophenylazo) substituted phenols, which are precursors for 2H-benzotriazole UV absorbers.

摘要： Provided is a process for preparing 2H-benzotriazole UV absorbers containing a perfluoroalkyl moiety at the 5-position of the benzoic ring, for example a trifluoromethyl group, which involves digitizing the perfluoroalkyl substituted o-nitroaniline using concentrated sulfuric acid plus sodium nitrite or nitrosylsulfuric acid to form the corresponding monoazobenzene intermediate via the diazonium salt intermediate which is reduced to the corresponding 5-perfluoroalkyl substituted 2H-benzotriazole UV absorber compound by conventional reduction means.

摘要： A process for preparing 2H-benzotriazole UV absorbers containing a perfluoroalkyl moiety at the 5-position of the benzo ring, preferably a trifluoromethyl group, involves diazotizing the perfluoroalkyl substituted o-nitroaniline using concentrated sulfuric acid plus sodium nitrite or preferably nitrosylsulfuric acid to form the corresponding monoazobenzene intermediate via the diazonium salt intermediate which is reduced to the corresponding 5-perfluoroalkyl substituted 2H-benzotriazole UV absorber compound by conventional reduction means.

摘要： An auger assembly transfers particulate material from a source area to a target area using a main auger, an open top swing auger or U-trough, and an extendable loading swing auger connected to one another. The main auger is supported on a wheeled frame similar to conventional grain augers while the U-trough is pivoted thereon, and the extendable loading swing auger is mounted on a rail system on the top of the U-trough. The inlet hopper of the extendable swing auger can be extended out to reach away from the main auger thus can be more easily positioned for proper alignment with the discharge hopper of a particulate material container even when the discharge hopper is within a confined space.
摘要翻译：螺旋钻组件使用主螺旋推运器，敞开的顶部摆动螺旋推运器或U形槽以及彼此连接的可延伸的装载摆动螺旋钻将颗粒材料从源区域转移到目标区域。主螺旋钻支撑在类似于常规谷物螺旋钻的轮式框架上，同时U形槽枢转在其上，并且可延伸的装载摆动螺旋推运器安装在U槽顶部的轨道系统上。可延伸的旋转螺旋推运器的入口料斗可以伸出以远离主螺旋推运器，因此即使排出料斗位于限制空间内的情况下，也可以更容易地定位以便与颗粒物料容器的排出料斗正确对准。
