Aniline has various uses – it is used to prepare other chemical substances to make polymers, and as we mentioned earlier, it is used in the dye industry as well. In this section, we will learn all about the uses of aniline.

Aniline is used to make chemical substances called isocyanates. Why are isocyanates important? Isocyanates are needed in the production of polyurethane. Polyurethane is used in making plastic, building thermal foam insulation for buildings and for refrigerators, and making spandex fibers for athletic clothing.
