With major production starting in the Industrial Revolution, hydrochloric acid is used in the chemical industry as a chemical reagent in the large-scale production of vinyl chloride for PVC plastic, and MDI / TDI for polyurethane. It has numerous smaller - scale applications, including household cleaning, production of 23PDF Image | Chlorine Characteristics
