Types of chemical industries on the basis of application:
On the basis of application, Chemical industries are classified as
1. Industries manufacturing Basic chemicals
2. Industries manufacturing Fine chemicals
3. Industries manufacturing Specialty chemicals
Basic industrial chemicals include fertilizers, organic and inorganic chemicals, dyes, resins, explosives, synthetic fibre, plastics, rubber etc. Fine chemicals are produced in limited volumes and at relatively high prices according to exact specifications, mainly by traditional organic synthesis in multipurpose chemical plants.
Fine chemicals are used as starting material for specialty chemicals, particularly pharmaceuticals, biopharmaceuticals and agrochemicals.
Specialty chemicals are particular chemical products which provide a wide variety of effects on which many other industry sectors rely. These are usually manufactured in batch chemical plants using batch processing techniques. Most of these chemicals are organic chemicals.
