Differentiate between heavy chemicals and fine chemicals with examples
Answers
Answer:
Fine chemicals are complex, single, pure chemical substances, produced in limited quantities in multipurpose plants by multistep batch chemical or biotechnological processes.Fine chemicals are used as starting materials for specialty chemicals, particularly pharmaceuticals, biopharmaceuticals and agrochemicals. Examples of fine chemicals include flavors and fragrances, photographic chemicals, pharmaceutical and biological products and intermediates.
Heavy chemicals are chemicals produced and handled in large lots (as a ton or more a day) and often in a more or less crude state —used especially of acids (as sulfuric acid), alkalies, and salts. Some examples of bulk chemicals are ammonia, sulfuric acid, and sodium hydroxide, which are all made at large chemical plants via a variety of different processes.
