 Thiophene present in the crude benzene fraction generated by the coking tar impurities. Close due to the boiling point of the thiophene and benzene, it is difficult to separate the two general fractionation. Distillation extraction method in the world hydrotreating method, sulfur the suan refined method and solvent extraction. Hydrotreating method is the high cost of investment, industrial production is not desirable; serious sulfur suan method pollution, low yield, post-processing difficulties, but also in the case of the backward process, only a small amount of coking plant using this method to produce a small amount of thiophene; solvent extraction method small investment, high yield, high purity, suitable for large-scale production. China is still not well for thiophene extraction, refining, waste of limited resources, and causing serious environmental pollution. Due to the presence of trace thiophene in benzene as solvent, chemical synthesis, seriously affect the product quality, or even scrapped.
