Technology Process of Sodium borohydride-11B

There total 3 articles about Sodium borohydride-11B 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:

Trimethylborat (3349-42-6) + sodium hydride (7646-69-7) → sodium borohydride (72901-46-3)

Guidance literature:

In neat (no solvent); followed the procedure of Schlesinger et al. (J.Am.Chem.Soc. 75 (1953) 195); B(OMe)3 added to a stirred paste consisting of an excess NaH heatedto 200°C; extracted with propyl amine; impurities removed by disolving Na(11)BH4 in diglyme; filtration in vacuo;

DOI:10.1016/j.cplett.2008.04.130

Reference yield:

methanol (67-56-1) + (11)B-boric acid (13813-78-0) + sodium hydride (7646-69-7) → sodium borohydride (72901-46-3)

Guidance literature:

In methanol; boric acid reacted with CH3OH; trimethylborane extd.; added dropwise to NaH; stirred at 220°C;
