Carbolic acid, also known as phenol, is a white crystalline substance with a strong, distinct odor. It was first synthesized from coal tar in the 19th century and has since been used for a variety of purposes.
In the late 19th and early 20th centuries, carbolic acid was used as an antiseptic and disinfectant in surgeries and hospitals. It was also used as an ingredient in some soaps and cleaning products.
In modern times, carbolic acid is used primarily as a raw material in the production of a variety of chemicals and products, including plastics, resins, and dyes. It is also used as an intermediate in the production of certain pharmaceuticals.
Carbolic acid can be toxic when ingested, inhaled, or applied to the skin. It can cause skin irritation and chemical burns, as well as serious damage to the eyes and respiratory system. Because of its toxicity, carbolic acid should only be handled and used with caution, and under the supervision of a trained professional.
