Description

General description

Potassium bicarbonate (Potassium hydrogen carbonate) is an inexpensive, nontoxic base. It is used to regulate pH or as a reagent.

Application

Potassium bicarbonate is used:

In the synthesis of cyclic ammonium cation N,N-dimethyl-3,5-dimethylpiperidinium (DMDMP).
As a base in the preparation of glycerol carbonate and glycidol from 3-chloro-1,2-propanediol (HAL).

Chromatin states must be maintained during cell proliferation to uphold cellular identity and genome integrity. Inheritance of histone modifications is central in this process. However, the histone modification landscape is challenged by incorporation of new unmodified histones during each cell

Oil formation from glucose with formic acid and cobalt catalyst in hot-compressed water.

Masaru Watanabe et al.

Carbohydrate research, 341(18), 2891-2900 (2006-11-01)

Liquefaction of glucose into oil was examined in hot-compressed water at 300 degrees C and 30 or 60 min in a tumbling batch reactor. The effects of alkali (KHCO(3)), a hydrogenating agent (HCO(2)H), and a cobalt catalyst (Co(3)O(4)) were studied.
