Heavy chemicals are the essential chemicals for all branches of

industry. Their manufacture amounts to thousands of tonnes per week.

Heavy chemicals include tetraoxosulphate (iv) acid [most important],

lime, caustic soda, caustic potash disodium trioxocarbonate (iv),

trioxonitrate (v) acid and bleaching powder. They are used in the

manufacture of glass; the processing of textiles, both natural fibres,

such as cotton, linen and wool, and artificial fibres, such as nylon,

rayon and Terylene; the manufacture of soaps; the manufacture of

metals and paints, to mention but a few uses. Besides their uses in

general industry, heavy chemicals are also used in all branches of

chemical industry as reagents for the various processes in the

manufacture of the final product.

On the other hand, fine chemicals are less often used than heavy

chemicals. However, tens of tonnes are produced monthly to meet

consumers needs. They are of higher purity than the heavy chemicals.

They include dyes, analytical reagents, photographic chemicals,

additives for fuels and paints, cosmetics and perfumes. They are more

expensive than the heavy chemicals.

Before reading this article, I had a hard time understanding the difference between heavy and fine chemicals. It's really interesting how fine ones are of higher purity. I had no idea that heavy chemicals were used to make glass! This is really helpful information to know. https://nmspecialtychemicals.com/
