Chemical Properties
colourless liquid
Definition
ChEBI: A polyether that consists of undecane in which the carbon atoms at positions 3, 6 and 9 are replaced by oxygen atoms.
General Description
Clear colorless viscous liquid.
Air & Water Reactions
Highly flammable. May be sensitive to prolonged exposure to air. Can form explosive peroxides. Vapor-air mixtures are explosive above the flash point. Water soluble.
Reactivity Profile
2-Ethoxyethyl ether is incompatible with strong acids. 2-Ethoxyethyl ether is also incompatible with strong oxidizing agents.
Fire Hazard
2-Ethoxyethyl ether is combustible.
Safety Profile
Moderately toxic by
ingestion. An experimental teratogen. Other
experimental reproductive effects. An eye
irritant. Flammable when exposed to heat or
flame. When heated to decomposition it
emits acrid smoke and irritating fumes. See
also GLYCOL ETHERS.
Purification Methods
Dry the ether with MgSO4, then CaH2 or LiAlH4, under N2. If sodium is used, the ether should be redistilled alone to remove any products which may be formed by the action of sodium on the ether. As a preliminary purification, the crude ether (2L) can be refluxed for 12hours with 25mL of conc HCl in 200mL of water, under reduced pressure, with slow passage of N2 to remove aldehydes and other volatile substances. After cooling, add sufficient solid KOH pellets (slowly and with shaking until no more dissolves) to give two liquid phases. The upper of these is decanted, dried with fresh KOH pellets, decanted, then refluxed over, and distilled from sodium. It can be passed through (alkaline) alumina prior to purification.

Check Digit Verification of cas no
The CAS Registry Mumber 112-36-7 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 2 respectively; the second part has 2 digits, 3 and 6 respectively.
Calculate Digit Verification of CAS Registry Number 112-36:
(5*1)+(4*1)+(3*2)+(2*3)+(1*6)=27
27 % 10 = 7
So 112-36-7 is a valid CAS Registry Number.

Paragraph 0050; 0051, (2016/10/17)
PROBLEM TO BE SOLVED: To provide a method for producing a (poly)alkylene glycol diether, introducing the oxyalkylene groups of the optional mole number of addition and optional terminal alkyl groups by using a metallosilicate catalyst having 10 to 1,000 ratio of SiO2/M2O3as an ether interchange reaction catalyst. SOLUTION: This method for producing the (poly)alkylene glycol diether includes a process of obtaining the (poly)alkylene glycol diether by the ether interchange reaction of a first (poly)alkylene glycol monoether with a second (poly)alkylene glycol monoether in the presence of the metallosilicate catalyst having 10 to 1,000 ratio of SiO2/M2O3(wherein, M is ≥1 kind selected from the group consisting of Al, Ga, Ge, B, Zn, P, Zr, Ti, Cr, Be, V and As).

SYNTHESIS OF DIALKYL ETHERS OF POLYETHYLENE GLYCOLS
Barnakov, Ch. N.,Volgin, A. A.
, p. 152 - 155 (2007/10/02)
Methods were developed for synthesis of dimethyl and diethyl ethers of polyethylene glycols in one step (without isolation of intermediates) with the general formula R(OC2H4)mOR, where R=CH3, C2H5 and m=2-6 (degree of polyglycolicity).As starting materials monomethyl and monoethyl ethers of polyethylene glycols of the formula R(OC2H4)nOH were used, where n=1-3.As reagents toluenesulfonyl chloride and methanesulfonyl chloride were used.
