Research of Clean Technology for Producing Sodium Saccharin

A clean technology for producing sodium saccharin was established by conducting overall modification of the conventional technology, and the modified technology was applied in industrial production of sodium saccharin. It has been found that the new technology is advan- tageous in that the raw materials and energy sources can be recycled and reused more efficient- ly, and the wastewater is qualified in terms of Chinese national standard for discharge. At the same time, the castoff and its treatment charge is decreased; the clean producing ability is im- proved greatly; the economic benefit, social benefit and environmental benefit are remarkable. This indicates that the new technology can be well used to save energy, reduce consumption and pollution, and increase efficiency for production of sodium saccharin.
