 The next time you look at tights, certain paints, or even plastics used in window frames, you may want to think about the raw materials from which they are made. Do you know any of these materials? Pause the video, think, and resume when ready. If you set nylon for tights, you'd be right. If you set polyurethane, you'd be right for paints and coatings. Finally, plastic window frames are made of PVC. These contain a plasticizer, allowing the frames to be easily molded. All of these materials require adipic acid in their production. Usually, benzene is used to make this compound, but unfortunately, benzene is carcinogenic or cancer-causing. Instead, glucose and a special enzyme extracted from genetically modified bacteria can be used to produce adipic acid. What do you think is the advantage in doing the synthesis in this way? Pause the video, think about this, and resume when ready. An answer is that glucose is harmless and is essentially sugar, so conducting the synthesis in this way protects the workers who would produce this compound by coming into contact with carcinogenic benzene.
