Colorless liquid with a mild, ether-like odor. Experimentally determined detection and recognition
odor threshold concentrations were 1.6 mg/m3 (330 ppbv) and 3.1 mg/m3 (640 ppbv), respectively
(Hellman and Small, 1974).
Uses
Different sources of media describe the Uses of 110-49-6 differently. You can refer to the following data:
1. Lacquer industry; textile printing;
manufacture of photographic film, coatings,
and adhesives
2. Industrial solvent.
General Description
A clear colorless liquid with a pleasant odor. Flash point of 135°F. Denser than water and soluble in water. Vapors are heavier than air.
Air & Water Reactions
Flammable. Water soluble. Reacts slowly in water to form acetic acid and methyl alcohol; the reaction is not violent.
Reactivity Profile
Esters react with acids to liberate heat along with alcohols and acids. Strong oxidizing acids may cause a vigorous reaction that is sufficiently exothermic to ignite the reaction products. Heat is also generated by the interaction of esters with caustic solutions. Flammable hydrogen is generated by mixing esters with alkali metals and hydrides.
Hazard
Toxic by ingestion, inhalation, and skin
absorption. Moderate fire risk. Toxic by skin
absorption.
Health Hazard
May cause irritation if splashed into eyes. Can be absorbed through the skin. Swallowing a large single dose or absorbing larged amount through skin could result in death. It is unlikely that air levels of the compound would be dangerous unless it is heated.
Safety Profile
Moderately toxic by
ingestion, intraperitoneal, and subcutaneous
routes. hfddly toxic by inhalation and skin
contact. Human systemic effects by
inhalation: eye lachrymation, cough, and
pulmonary changes. Experimental
reproductive effects. Mutation data
reported. An inhalation irritant in humans.
An eye irritant. Flammable liquid when
exposed to heat or flame; can react with
oxidizing materials. A moderate explosion
hazard. To fight fire, use CO2, dry chemical.
When heated to decomposition it emits
acrid smoke and irritating fumes. See also
GLYCOL ETHERS.
Potential Exposure
Methoxyethyl acetate is used as
a solvent for resins, oils, greases and inks. It is also an
ingredient of lacquers, paints and adhesives.
Environmental fate
Chemical/Physical. Hydrolyzes in water forming methyl cellosolve and acetic acid.
At an influent concentration of 1,024 mg/L, treatment with GAC resulted in an effluent
concentration of 886 mg/L. The adsorbability of the carbon used was 28 mg/g carbon (Guisti et
al., 1974).
Shipping
UN1189 Ethylene glycol monomethyl ether
acetate, Hazard Class: 3; Labels: 3-Flammable liquid.
Purification Methods
Shake the methoxy-ethane with anhydrous Na2CO3, filter and distil it in a vacuum. Redistillation can be then be carried out at atmospheric pressure. [Dunbar & Bolstad J Org Chem 21 1041 1956, Beilstein 2 IV 214.]
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. Beware of possible presence of peroxides in
which case open burning may be used
Check Digit Verification of cas no
The CAS Registry Mumber 110-49-6 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 0 respectively; the second part has 2 digits, 4 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 110-49:
(5*1)+(4*1)+(3*0)+(2*4)+(1*9)=26
26 % 10 = 6
So 110-49-6 is a valid CAS Registry Number.

, p. 712 - 716 (2013/01/09)
A solid superbase with H- above 26.5 has been obtained through thermal treatment of sodium stannate hydrate. It was found to be an efficient catalyst for anti-Markovnikov hydroamination and hydroalkoxylation of electron-deficient olefins under mild conditions.
Indium triiodide catalysed one-step conversion of tetrahydropyranyl ethers to acetates with high selectivity
Ranu, Brindaban C.,Hajra, Alakananda
, p. 355 - 357 (2007/10/03)
Chemoselective one-step conversion of tetrahydropyranyl ethers of primary alcohols to corresponding acetates was carried out. The reaction occurred through an indium triiodide catalyzed transesterification process in ethyl acetate. The method provided advantages such as operational simplicity, acceptable reaction conditions to acid-sensitive functional groups and good yield.
