Method for preparing sodium 3-nitrobenzene sulfonate and derivative thereof through chlorosulfonic acid sulfonation

The invention discloses a method for preparing sodium 3-nitrobenzene sulfonate and a derivative thereof through chlorosulfonic acid sulfonation. The method comprises the following steps: 1) putting anitrobenzene raw material and chlorosulfonic acid into a reaction container, heating to 90-150 DEG C, keeping the temperature, carrying out a sulfonation reaction, and discharging a hydrogen chloridegas generated in the reaction process outside the reaction system in time, wherein the mole ratio of the nitrobenzene raw material to the chlorosulfonic acid is 1:(0.4-0.6); 2) carrying out aftertreatment on the reaction liquid obtained in the step 1) by using soda, thereby obtaining the sodium 3-nitrobenzene sulfonate or the derivative thereof. By adopting the method, a reverse thinking mode is adopted, the amount of the chlorosulfonic acid is reduced till being smaller than that of the nitrobenzene, and then the small amount of the chlorosulfonic acid can be converted by using the excessiveamount of the nitrobenzene; therefore, the method disclosed by the invention has no problem of treating residual chlorosulfonic acid; in addition, the excessive nitrobenzene can be easily recycled andcirculated, the hydrogen chloride as a byproduct can be also easily separated and recycled.

Research on controllable degradation of sulfonylurea herbicides

In order to seek ecologically safer and environmentally benign sulfonylurea herbicides (SU), insight into the structure/bioassay/soil degradation tri-factor relationship was first established. With the introduction of various groups (alkyl, nitro, halogen, cyano etc.) at the 5th position of its benzene ring, structural derivatives of chlorsulfuron were designed, synthesized, and evaluated for their herbicidal activity. The structures of the title compounds were confirmed by infrared spectroscopy, ultraviolet spectroscopy, 1H and 13C NMR, mass spectrometry, elemental analysis and X-ray diffraction. Bioassay results confirmed that most derivatives retained their superior herbicidal activities in comparison with chlorsulfuron. After investigating the soil degradation behavior of each molecule under set conditions, it was found that structures with electron-withdrawing substituents at the 5th position of the benzene ring retained their long degradation half-lives, yet the introduction of electron-donating substituents accelerated the degradation rate. These results will provide a valuable clue to further explore the potential controllable degradation of SU and other herbicides, and to discover novel herbicides that are favorable for environmentally and ecologically sustainable development.
