Sažetak
A chemical reaction is to be carried out in a way that industrial waters, after the final product isolation, contain as little as possible of different chemicals and can be drained off in the sewage system. In the case of mother liquor loaded with unreacted raw materials or with by-products, the isolation and recycling of these substances is important. The precipitation and crystallization can be used in isolation of chemicals from mother liquors. As the model process, the isolation of sulfanilic acid from mother liquor of 5-aminosalicylic acid synthesis was studied.
