2-phenoxy ethanol - Introduction
Slightly rose fragrance, low volatilization, colorless and transparent with high boiling point. Easily soluble in alcohol, ether and sodium hydroxide solution, slightly soluble in water. It is stable in acid or alkali and has a burning smell. Because it is miscible with many organic solvents and has strong permeability, it has outstanding comprehensive performance compared with isophorone (commonly known as 783), DBE and benzyl alcohol, and can be used instead of full performance.

| Toxicity | Ethylene glycol phenyl ether is currently a standard preservative compound and generally does not release formaldehyde. Compared with compounds that release formaldehyde, phenoxyethanol is a better substitute. The data in the 2007 edition of "Current Situation and Development of Cosmetic Preservatives" show that the toxicological data LD50 (median lethal dose) of phenoxyethanol: 3000 mg/kg in rats and 4000 mg/kg in mice, which is mild toxicity. |
| synthesis | phenol and ethylene oxide are condensed under the action of sodium acetate or sodium hydroxide. the reaction is as follows: the method needs to be carried out at a temperature of 20 ℃ and a pressure of 0.2-0.25 MPa. Suitable for mass and industrial production. |
| use | ethylene glycol phenyl ether (KL-EPH) is a typical high boiling point organic solvent, which has been widely used in Europe and America as early as the 1970 s. It is a colorless and transparent liquid with slightly rose fragrance, low volatilization and high boiling point. Because it can be miscible with many organic solvents and has strong permeability, it has outstanding comprehensive performance compared with isophorone (commonly known as 783), DBE and benzyl alcohol, and can be used instead of full performance. KL-EPH has excellent solubility to acrylic resin, nitrocellulose, ethyl cellulose, epoxy resin, alkyd resin, phenoxy resin and other resins, and can be miscible with alcohol and ether, commonly known as "universal solvent". ethylene glycol phenyl ether can be used as water-based coatings and ink film-forming additives, fragrance fixatives, ink fluency agents, medicinal antiseptic fungicides, electronic cleaning agents and ink slow-drying agents, etc |
| production method | is obtained by the addition of phenol and ethylene oxide. The reaction is carried out in the presence of sodium acetate or sodium hydroxide, the reaction temperature is 200 ℃, and the pressure is 0.2-0.25MPa. |
