For more, you can study these:

Shreve's Chemical Process Industries(George T. Austin) --> for topics of Industrial chem,
Organic Chem (J. March),
Organic chem (Morrison and Boyd),
Atkins Physical chem,
Inorganic chem (J. D. Lee)
Inorganic chem (G. D. Tuli)

Can't remember more names right now, I think these are enough
find a library near you for all these...
Hope this helps
