111-55-7 Usage
Chemical Properties
clear liquid
Uses
Different sources of media describe the Uses of 111-55-7 differently. You can refer to the following data:
1. Solvent for oils, cellulose esters, explosives, etc.
2. EGDA imparts excellent flow properties in baking lacquers and enamels and where thermoplastic acrylic resins are used. It is also a good solvent for cellulosic coatings and can be used in some ink systems such as screen inks. It has found use as a perfume fixative, and has reported applications in waterborne adhesives.
3. Ethylene glycol diacetate may be used as an acyl donor for the in situ generation of peracetic acid, during the chemoenzymatic synthesis of caprolactone. It may be employed as a precursor for the enzymatic synthesis of poly (ethylene glutarate).
General Description
Colorless liquid with a mild pleasant odor. Density 9.2 lb /gal. Flash point 191°F. Boiling point 369°F. Combustible but requires some effort to ignite. Used in the manufacture of perfumes, printing ink, lacquers and resins.
Air & Water Reactions
Water soluble.
Reactivity Profile
Ethylene glycol diacetate reacts with aqueous 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 with caustic solutions. Flammable hydrogen is generated with alkali metals and hydrides.
Health Hazard
Inhalation is not hazardous. Liquid causes mild irritation of eyes. Ingestion causes stupor or coma.
Fire Hazard
Ethylene glycol diacetate is combustible.
Flammability and Explosibility
Notclassified
Safety Profile
Moderately toxic by
intraperitoneal route. Mildly toxic by
ingestion and skin contact. An eye irritant.
Combustible when exposed to heat or
flame; can react with oxidzing materials. To
fight fire, use alcohol foam, CO2, dry
chemical. When heated to decomposition it
emits acrid smoke and irritating fumes.
Purification Methods
Dry the di-ester with CaCl2, filter (excluding moisture) and fractionally distil it under reduced pressure. [Beilstein 2 IV 1541.]
Check Digit Verification of cas no
The CAS Registry Mumber 111-55-7 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, 5 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 111-55:
(5*1)+(4*1)+(3*1)+(2*5)+(1*5)=27
27 % 10 = 7
So 111-55-7 is a valid CAS Registry Number.

A convenient and sustainable method for the synthesis of glycol diesters was developed through the depolymerization of polyethylene glycols (PEGs) with carboxylic acids using proton-exchanged montmorillonite as an efficient solid acid catalyst. Several functionalized glycol diesters were obtained in good yields from PEGs and readily available carboxylic acids. Upon reaction completion, the catalyst could be easily separated by filtration and reused with its activity remaining unchanged.

Paragraph 0023-0028, (2017/02/24)
The invention discloses a method for synthesizing glycol diacetate under the catalytic action of an acidic immobilized ionic liquid. Under the catalytic action of an acidic immobilized ionic liquid, ethylene glycol and acetic acid used as raw materials are directly esterified to synthesize the glycol diacetate in a batch rectification tower, wherein the acidic immobilized ionic liquid is an acidic ionic liquid immobilized on the surface or in the pores of a support. The method has the advantages of high reaction selectivity, mild conditions, high raw material conversion rate and the like, and the catalyst can be easily separated from the reaction system and is recyclable. The glycol diacetate yield of the method can reach 99.4%, and the reaction selectivity can reach 99.5% above.
