what kinds of processes do chemists aim to design?
those which don’t require a solvent and use non-hazardous starting materials
what kinds of production methods do chemists aim to design?
those with fewer steps which have a high percentage atom economy
why do chemists aim to design processes which don’t require a solvent?
• separation processes are required to remove the products from the solvent - this can be costly and cause a loss of yield • solvents are often flammable and toxic
why do chemists aim to design production methods with fewer steps?
• they produce less waste • they use less energy • they have a higher yield
why do chemists aim to design production methods with a high percentage atom economy?
• fewer separating processes are required • less material is wasted (more sustainable)
