Useful:

• Uses: Organic condensations and alkylations. It is used as a strong reducing agent and inmaking super bases RNHK and ROK(whereRis an alkyl group) (Sullivan andWade 1980).It is sold as 35 wt% dispersion in mineral oil. Potassium Hydride is used in preparation of Hydroxy-Xanthone derivatives via Isoprenylation followed by Claisen rearrangement starting from Fluoroxanthone derivatives.

Technology Process of Potassium hydride

There total 1 articles about Potassium hydride 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:

hydrogen (1333-74-0) + potassium (7440-09-7) → potassium hydride (7693-26-7)
