The spectral and chemical properties of potassium fluoride on activated alumina, an extensively used basic catalyst in organic synthesis, show that its unusually high reactivity relative to other fluoride-containing basic systems is due to the reaction of

The invention discloses a preparation method of clorsulon. The preparation method comprises the steps: carrying out condensation on m-nitrobenzaldehyde with chloroform at a low temperature, then chloridizing, and carrying out elimination, hydrazine hydrate reduction, chlorosulfuric acid sulphonation and ammonification to obtain clorsulon. The use of benzene with relatively high toxicity is avoided, the use of chlorine with relatively large dangerousness is also avoided, the reduction reaction adopts more environmentally-friendly hydrazine hydrate, hydrazine hydrate reduction has less solid waste than iron powder reduction, an excellent catalyst ferric trichloride and an activated carbon carrier are selected, a by-product nitrogen gas has a good protective effect on the product, the product quality is high, the yield is equivalent to the yield reported in literature, the process is simplified, reaction conditions are mild, and the preparation method is environmentally friendly and has good industrial application prospects.

FLUORIDE-ALUMINA REAGENTS: THE ACTIVE BASIC SPECIES
Ando, Takashi,Clark, James H.,Cork, David G.,Hanafusa, Terukiyo,Ichihara, Junko,Kimura, Takahide

Comparison of KF and NaF impregnated on active alumina shows that the formation of strong base by fluoride reaction with alumina cannot totally explain the extremely high reactivity of KF-alumina as a heterogeneous base for catalytic as well as non catalytic reactions.At least three mechanisms apparently give rise to the high basicity.
