4-Carboxybenzaldehyde (CBA) is an organic compound with the formula OCHC 6 H 4 CO 2 H. It consists of a benzene ring substituted with both an aldehyde and a carboxylic acid, with these functional groups on opposite corners of the ring. This compound is formed in 0.5% yield as a byproduct in the production terephthalic acid from p-xylene. Since ...
IUPAC states that, "As one of its major activities, IUPAC develops Recommendations to establish unambiguous, uniform, and consistent nomenclature and terminology for specific scientific fields, usually presented as: glossaries of terms for specific chemical disciplines; definitions of terms relating to a group of properties; nomenclature of chemical compounds and their classes; terminology ...
When substituted 2-formylbenzoic acid, potassium cyanide and equimolar amounts of primary aromatic amines and acetic acid are used, substituted isochromes-1-ones (isocumarins, 1H-2-benzopyran-1-ones) are obtained in good yields.

Potassium carbonate (K 2 CO 3 or potash) is used in the manufacture of glass, soap, color TV tubes, fluorescent lamps, textile dyes and pigments. [75] Potassium permanganate (KMnO 4) is an oxidizing, bleaching and purification substance and is used for production of saccharin. Potassium chlorate (KClO 3) is added to matches and explosives.
Potassium benzoate (E212), the potassium salt of benzoic acid, is a food preservative that inhibits the growth of mold, yeast and some bacteria. It works best in low- pH products, below 4.5, where it exists as benzoic acid.
Potassium compounds are those chemical compounds which contain the chemical element potassium. Subcategories This category has the following 3 subcategories, out of 3 total.
Polystyrene sulfonic acid, the acid whose salts are the polystyrene sulfonates, has the idealized formula (CH 2 CHC 6 H 4 SO 3 H) n. The material is prepared by sulfonation of polystyrene: (CH 2 CHC 6 H 5) n + n SO 3 → (CH 2 CHC 6 H 4 SO 3 H) n. Several methods exist for this conversion, which can lead to varying degree of sulfonation.
