Description

General description

Potassium hydroxide is an inorganic salt mainly used as a precursor to synthesize other potassium compounds such as potassium acetate, potassium bicarbonate and potassium carbonate. On a commercial scale, it is synthesized by the electrolysis of potassium chloride.

Application

Redi-Dri^™ is an innovative packaging product line that helps eliminate clumping material by adding extra packaging process steps without any chemical additives, anti-clumping agents, or hydrophobic compounds. Redi-Dri^™ offers a more convenient and safer way to handle the products.

Potassium hydroxide may be used in the following processes:

Conversion of nitriles to amide in tert-butanol.
Cross-coupling of aryl halides with different sulfur-, oxygen- and nitrogen-based nucleophiles in dimethyl sulfoxide.
As an activator for the preparation of activated carbons from corn cobs.
As a base for the N-alkylation of nitrogen heterocycles in polyethylene glycol-ether solvents.
Synthesis of (S)-1-(4-benzyl-2-thioxothiazolidin-3-yl)propan-1-one from (S)-phenylalaninol.
To catalyze the polymerization of propylene oxide.

Tailored surface birefringence by femtosecond laser assisted wet etching.

Rokas Drevinskas et al.

Optics express, 23(2), 1428-1437 (2015-04-04)

Surface texturing is demonstrated by the combination of wet etching and ultrafast laser nanostructuring of silica glass. Using potassium hydroxide (KOH) at room temperature as an etchant of laser modified glass, we show the polarization dependent linear increase in retardance

Identification of the expressed protein and the impact of change in ascorbate peroxidase activity related to endodormancy breaking in Pyrus pyrifolia.

Yoshihiro Takemura et al.

Plant physiology and biochemistry : PPB, 86, 121-129 (2014-12-02)

Endodormancy is an important feature of perennial deciduous fruit trees that survive in the extreme climates brought about by seasonal variation. To acquire a comprehensive knowledge of the biochemical processes occurring just before endodormancy breaking, the buds collected in the

Defining immunological impact and therapeutic benefit of mild heating in a murine model of arthritis.

Chen-Ting Lee et al.

PloS one, 10(3), e0120327-e0120327 (2015-03-21)

Traditional treatments, including a variety of thermal therapies have been known since ancient times to provide relief from rheumatoid arthritis (RA) symptoms. However, a general absence of information on how heating affects molecular or immunological targets relevant to RA has
