These results might be used as the basis of crystallizing separation of potassium hexaniobate and KOH involved in the disposal of low-grade refractory niobium-tantalum ore by the KOH sub-molten method in the clean metallurgy process.

The highmolar mass dihydroxypolydimethylsiloxane(107 silicone rubber) was prepared by the polycondensation of dihydroxypolydimethylsiloxane oligomer(linear),as material and KOH aqueous solution as catalyst.

A series of high specific surface area activated carbons were prepared with char of the agricultural and forest waste-tobacco stems as raw materials and KOH as activating agent using a microwave heating procedure.

Method:The titled compound was synthesized with 2-pyrrolidione,bromoacetoacetate and potassium hydrate as the material,with TEBA as phace transfer catalst, and the method had only one-step advantage.
