4,*-Dinitro**-sec-Butylphenol(DNBP)
Uses
The product is mainly used in styrene monomer. It is high temperature inhibitor. And it is widely used in insecticide staining agent and precision chemicals intermediate product.
Characteristics
DNBP is the high-temperature and efficiency inhibitor required for the styrene distillation process, having more effective inhibition than other nitro-phenol inhibitor. With much better oil-soluble than the first generation (DNP) and second-generation (DNPC) inhibitor, in winter it is not easy to isolate the crystallization and plug the styrene plant pipelines, and is less toxic. At the same time it can reduce environmental pollution and increase the production capacity of styrene.
