Uses
Used in Coatings Industry:
Ethylene glycol monoethyl ether acetate is used as a solvent for nitrocellulose and some resins, particularly in the semiconductor industry. It is also used in coatings for brushing on, dip coating, and spraying, as well as for stove enamels.
Used in Paints, Lacquers, and Varnishes:
Ethylene glycol monoethyl ether acetate is used as a solvent to dissolve resin, leather, and ink. It is essential for the formulation of paints, lacquers, and varnishes for industrial use. Additionally, it is used to study the field evaluation of a passive badge for measuring the level of 2-ethoxyethyl acetate.
Used in Varnish Removers, Wood Stains, Textiles, and Leather:
Ethylene glycol monoethyl ether acetate serves as a solvent for nitrocellulose, oils, and resins. It is also used to retard "blushing" in lacquers, making it a valuable component in varnish removers, wood stains, textiles, and leather products.
Used in Cleaners and Paint Removers:
Another application for Ethylene glycol monoethyl ether acetate is as an additive in cleaners and paint removers, where its solvent properties help in the effective removal of dirt and paint.
Air & Water Reactions
Flammable. Slightly soluble in water.
Reactivity Profile
Mixing Ethylene glycol monoethyl ether acetate in equal molar portions with any of the following substances in a closed container caused the temperature and pressure to increase: chlorosulfonic acid, oleum, and vinyl acetate, NFPA 1991.
Hazard
Toxic by ingestion and skin absorption.
Toxic by skin absorption.
Health Hazard
Vapors irritate nose and eyes in high concentrations. Liquid irritates skin in prolonged or repeated contact.
Fire Hazard
HIGHLY FLAMMABLE: Will be easily ignited by heat, sparks or flames. Vapors may form explosive mixtures with air. Vapors may travel to source of ignition and flash back. Most vapors are heavier than air. They will spread along ground and collect in low or confined areas (sewers, basements, tanks). Vapor explosion hazard indoors, outdoors or in sewers. Runoff to sewer may create fire or explosion hazard. Containers may explode when heated. Many liquids are lighter than water.
Safety Profile
Moderately toxic by
ingestion and intraperitoneal routes. A skin
and eye irritant. An experimental teratogen.
Other experimental reproductive effects.
Flammable liquid when exposed to heat or
flame; can react with oxidizing materials.
Moderate explosion hazard in the form of
vapor when heated. Mild explosions have
occurred at the end of disullations. To fight
fire, use alcohol foam, CO2, dry chemical.
When heated to decomposition it emits acrid smoke and irritating fumes. See also
GLYCOL ETHERS.
Potential Exposure
This material is used as a solvent for
many different purposes; including for nitrocellulose and
other resins. Used in automobile lacquers to retard evaporation and impart a high gloss.
Environmental fate
Biological. Bridié et al. (1979) reported BOD and COD values of 0.74 and 1.76 g/g using
filtered effluent from a biological sanitary waste treatment plant. These values were determined
using a standard dilution method at 20 °C for a period of 5 d. The ThOD for 2-ethoxyethyl acetate
is 1.82 g/g.
Chemical/Physical. At an influent concentration of 1,000 mg/L, treatment with GAC resulted
in an effluent concentration of 342 mg/L. The adsorbability of the carbon used was 132 mg/g
carbon (Guisti et al., 1974).

Purification Methods
Shake the ethoxy-ethane with anhydrous Na2CO3, filter and distil it in a vacuum. Redistillation can then be carried out at atmospheric pressure. [Dunbar & Bolstad J Org Chem 21 1041 1956, Beilstein 2 IV 214.]
Incompatibilities
May form explosive mixture with air.
Incompatible with strong acids; strong alkalies; nitrates.
Violent reaction with oxidizers. May form unstable peroxides.
Softens many plastics. Attacks some plastics, rubber, and
coatings
Waste Disposal
Dissolve or mix the material
with a combustible solvent and burn in a chemical incinerator equipped with an afterburner and scrubber. All federal,
state, and local environmental regulations must be observed.
Check Digit Verification of cas no
The CAS Registry Mumber 111-15-9 includes 6 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 3 digits, 1,1 and 1 respectively; the second part has 2 digits, 1 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 111-15:
(5*1)+(4*1)+(3*1)+(2*1)+(1*5)=19
19 % 10 = 9
So 111-15-9 is a valid CAS Registry Number.

A process for the preparation of acetate
-
Paragraph 0054; 0055; 0056; 0057, (2017/01/26)
The invention relates to an acetate preparation method. The method comprises the following steps: carrying out a contact reaction of sec-butyl acetate and alcohol in the presence of an ester exchange catalyst under an ester exchange reaction condition, adding products obtained after the contact reaction into a separation tower, controlling the tower top temperature to separate unreacted sec-butyl acetate and sec-butyl alcohol generated after the reaction from the tower top, and carrying out normal-pressure or reduced-pressure flash evaporation to separate acetate generated after the reaction from a tower bottom fraction, wherein the alcohol is alcohol having a general formula of R(OH)n and/or polyol alkylether having at least one hydroxy group, R is a C5-C20 n-valence alkyl group, a C5-C20 n-valence alkenyl group, a C5-C12 n-valence cycloalkyl group or a C7-C20 n-valence aryl group, and n is an integer in a range of 1-5. The method has the advantages of high conversion rate of the alcohol as a reaction raw material, and high acetate selectivity.

, p. 2070 - 2073 (2016/04/26)
The acylation and transesterification of alcohols with vinyl acetate and carboxylic esters were investigated in the presence of a catalytic amount (1-10 mol %) of dilithium tetra-tert-butylzincate (TBZL) as a catalyst. The acylation proceeded quantitatively at 0 °C within 1 h. The transesterification occurred for a wide range of combinations of esters and alcohols at 0 to -40 °C. To the best of our knowledge, this is the first successful transesterification at such low temperatures. The time-conversion plots for the transesterification show that the reaction reached equilibrium within 5 min at 0 °C. The reaction proceeded quantitatively by addition of molecular sieves 4A. In addition, the transesterification proceeded even in the presence of H2O and amines.

Ranu, Brindaban C.,Dutta, Pinak,Sarkar, Arunkanti
, p. 2223 - 2225 (2007/10/03)
A very simple method has been developed for the acylation of alcohols and amines by ethyl acetate through an indium triiodide-catalysed transesterification process. Using this method acylation of a primary OH group in the presence of secondary and phenolic OH groups, and of a primary NH2 in the presence of secondary NH and primary OH have been achieved with high selectivity.

Vilcu, Rodica,Gainar, Ion,Maior, Ovidiu,Anitescu, Gheorghe
, p. 875 - 878 (2007/10/03)
The absorption of carbon dioxide in organic solvents containing acetyl groups (ethylene glycol diacetate, diethylene glycol diacetate, triethylene glycol diacetate, propylene glycol diacetate, ethyl cellosolve acetate, 1,4-butanediol diacetate, glycerol triacetate and β-phenyl acetate) is studied. Bunsen absorption coefficients in the range of 5 to 50 atm and at 25 deg C are obtained. Some considerations about the correlation between absorptive capacity and the molecular structure of these organic compounds are presented.
