5-Isobutylhydantoin
Structural type
Density: 1.1±0.1 g/cm3 (Predicted)
The application of 3-methyl-5-isobutylhydantoin in the purification of chlorine-containing wastewater is realized by grafting a modified polyamide membrane. The specific steps include grafting 3-methyl-5-isobutylhydantoin onto the polyamide membrane to protect the n-h bond in the polyamide by increasing the spatial site resistance and introducing protective groups, thereby improving the chlorine resistance of the membrane. This method not only preserves the secondary amine groups in the polyamide membrane, but also enhances its chlorine resistance, which is applicable to the chlorine resistance requirements in industrial wastewater treatment
