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.
Method for synthesis of vinyl acetate

Paragraph 0131; 0134; 0136, (2016/12/16)
The invention relates to a method for synthesis of vinyl acetate. The method mainly solves the problem that the existing vinyl acetate preparation method utilizing methyl acetate carbonylation and carboxide cracking has a low yield and low selectivity. The method provided through the invention comprises methyl acetate carbonylation for ethylidene diacetate preparation and ethylidene diacetate cracking for vinyl acetate preparation. A carbonylation catalyst comprises a carrier and rhodium, copper, lanthanum and lithium on the carrier. The carrier is at least one of silicon oxide and alumina. The method well solves the technical problem and can be used for vinyl acetate industrial production.
