GOST no data
CAS 111-90-0

Ethyl carbitol CH32(OCH2CH2)2OH is a colorless, volatile, flammable, hygroscopic liquid with a weak glycol odor. It is fully miscible in water and most organic solvents such as alcohols, chloroform, carbon tetrachloride, benzene, toluene and so on. Aliphatic hydrocarbons have a low solubility in ethyl carbitol.

As a monoethyl diethylene glycol ether ethyl carbitol possess both alcohol and ether chemical properties. It reacts with alkali metals releasing hydrogen to give corresponding salts. It can be also esterified by action of carboxilic or inorganic acids. Being treated with ethylene oxide at 150-200°C in the presence of alkaline catalysts ethyl carbitol forms ethyl ethers of higher polyethylene glycols.

Ethyl carbitol is a toxic compound. Its toxisity is similar to glycols action. The result of ingestion is central nervous system and kidney injury.

Production.

Industrially ethyl carbitol is produced by the reaction of ethyl alcohol with ethylene oxide at 180-200°C and pressure 3.0-3.5MPa in the presence of sodium hydroxide NaOH as a catalyst:

CH3CH2OH + 2(CH2CH2)O --> CH3CH2(OCH2CH2)2OH

Resulting mixture consists of ethyl ethers of mono-, di- and tri- ethylene glycols and can be separated by following rectification.

Uses.

  • as a high-boiling polar solvent;
  • as an effective extractive agent for mixtures separation;
  • as an additive for separation of mixtures by azeotrope distillation (e.g. for methanol and methyl acetate mixture separation);
  • as a solvent for ethereal oil in perfumery and cosmetics;
  • bactericide agent in deodorant and antiperspirant compositions;
  • as an absorbent for gases drying;
  • as a component of hydraulic and brake fluids, antifreezes;

  • Manufacturer(s) JSC "Nizhnekamskneftekhim" Inc.
