Technology Process of Tin powder

There total 477 articles about Tin powder which guide to synthetic route it. The literature collected by LookChem mainly comes from the sharing of users and the free literature resources found by Internet computing technology. We keep the original model of the professional version of literature to make it easier and faster for users to retrieve and use. At the same time, we analyze and calculate the most feasible synthesis route with the highest yield for your reference as below:

synthetic route:

Reference yield: 94.0%

vanadocene + dibutyltin dibenzoate (5847-54-1) → tin (7440-31-5) + 2C5H5(1-)*2V(3+)*4OCOC6H5(1-) = [(C5H5)V(OCOC6H5)2]2 + (Benzoyloxy)tributylstannan (4342-36-3) + dibutyltin (1191-48-6) + cyclopenta-1,3-diene (542-92-7,25568-84-7,7313-32-8)

Guidance literature:

In toluene; molar ratio Cp2V/Sn-compound 1/2, sealed ampoule, 20°C, 24 h;

Reference yield: 76.8%

stannous fluoride + silicon (7440-21-3) → tin (7440-31-5) + silicon tetrafluoride (7783-61-1)

Guidance literature:

In melt; placing of mixt. of Si with SnF2 (molar ratio SnF2:Si=2.00) in Fluoroplast-4 ampule, closing by screwed stopper, exposition for 1.00 h at 250°C; various product ratio yields for various conditions; cooling, stirring up in water, collection, drying;

Reference yield: 67.0%

vanadocene + dibutyltin dibenzoate (5847-54-1) → tin (7440-31-5) + 2C5H5(1-)*2V(3+)*4OCOC6H5(1-) = [(C5H5)V(OCOC6H5)2]2 + (Benzoyloxy)tributylstannan (4342-36-3) + cyclopenta-1,3-diene (542-92-7,25568-84-7,7313-32-8)
