The problem of known synthesis route
|
Complex route, difficult to realize
High cost of material, no profit
Insecurity of the process, flammability, explosive, and severe pollution
Low yield, severe waste of material
Low quality of product, difficult to meet customers’ need
High demand to equipment, need high temperature and pressure or vacuum, hard to realize large scale production
Need large bulk equipment, but small scale of manufacture, difficult to scale- up.
