溴仿（化学式：CHBr3）是卤仿之一，室温下为暗黄色的液体，有和氯仿类似的甜气味。它有限可溶于水，容易蒸发。折射率1.595（20°C、D），与乙醇、苯、氯仿、醚、石油醚、丙酮混溶，与水以1/800的比例溶解，少量自然存在于海洋植物中，进入环境中的溴仿大多是用氯气给水杀菌时的副产物。


溴仿可通过丙酮和次溴酸钠（溴与碱反应得到）发生卤仿反应、电解溴化钾的乙醇溶液或氯仿与溴化铝反应制取。


溴仿可作溶剂、选矿剂、镇静剂、阻燃剂、实验室试剂等。

Volkswagen Group MQB platform

Image
The Volkswagen Group MQB platform is the company's strategy for shared modular design construction of its transverse, front-engine, front-wheel-drive layout (optional front-engine, four-wheel-drive layout) automobiles. Volkswagen spent roughly $60bn [1] developing this new platform and the cars employing it. The platform underpins a wide range of cars from the supermini class to the mid size SUV class. MQB allows Volkswagen to assemble any of its cars based on this platform across all of its MQB ready factories. This allows the Volkswagen group flexibility to shift production as needed between its different factories. Beginning in 2012, Volkswagen Group marketed the strategy under the code name MQB , which stands for Modularer Querbaukasten , translating from German to "Modular Transversal Toolkit" or "Modular Transverse Matrix". [2] [3] MQB is one strategy within VW's overall MB (Modularer Baukasten or modular matrix) program which also includes th...
