Phenol  CAS# 108-95-2

Phenol is the easiest member of a classification of natural compounds possessing a hydroxyl team connected to a benzene ring or to a extra complicated fragrant ring system.
Also recognized as carbolic acid or monohydroxybenzene, phenol is a colorless to white crystalline fabric of candy odor, having the composition C6H5OH, bought from the distillation of coal tar and as a derivative of coke ovens.
Phenol has extensive biocidal properties, and dilute aqueous options have lengthy been used as an antiseptic. At greater concentrations, it motives extreme pores and skin burns; it is a violent systemic poison. It is a precious chemical uncooked cloth for the manufacturing of plastics, dyes, pharmaceuticals, syntans, and different products.
phenol crystal
Phenol melts at about 43°C and boils at 183°C. The pure grades have melting factor of 39°C, 39.5°C, and 40°C. The technical grades include 82%-84% and 90%-92% phenol. The crystallization factor is given as 40.41°C. The unique gravity is 1.066. It dissolves in most natural solvents. By melting the crystals and including water, liquid phenol is produced, which stays liquid at regular temperatures. Phenol has the uncommon property of penetrating residing tissues and forming a treasured antiseptic. It is additionally used industrially in reducing oils and compounds and in tanneries. The cost of different disinfectants and antiseptics is generally measured by means of evaluation with phenol.

Product Usage

Propionic acid is used in the productionof propionates used as mold inhibitors andpreservatives for grains and wood chips, inthe manufacture of fruit flavors and perfumebases, and as an esterifying agent.

Propionic Acid is the acid source of the propionates. propionic acid in the liquid form has a strong odor and is corrosive, so it is used as the sodium, calcium, and potassium salts as a preservative. these yield the free acid in the ph range of the food in which they are used. it functions principally against mold.
