112-60-7 Usage
Chemical Properties
Tetraethylene glycol is a high-boiling, clear liquid of low volatility. hygroscopic. It is completely miscible with water and a wide variety of organic solvents. insoluble in benzene, toluene, or gasoline. Combustible. For certain aliphatic hydrocarbons, it has a very slight affinity. Tetraethylene glycol is used as a coupling agent for blending water-soluble and water-insoluble compounds in such formulations as lubricants, glues, cork and textile products, etc.
Uses
Different sources of media describe the Uses of 112-60-7 differently. You can refer to the following data:
1. Solvent for nitrocellulose, plasticizer, lacquers,
coating compositions.
2. Tetraethylene glycol is used as a solvent to dissolve water-insoluble compounds. It is employed as a nitrocellulose solvent, a plasticizer, a natural gas desiccant, a hydraulic fluid and in lacquers and coatings. Furthermore, it is used in the synthesis of tetraethylene glycol methacrylate monomer. It acts as a chemical intermediate and acts as a solvent for the manufacturing of inks and dyes. In addition, it serves as a coupling agent in the production of textile lubricants and formulations.
Production Methods
Tetraethylene glycol is prepared commercially by adding
ethylene oxide to ethylene glycol, diethylene glycol, or water
in the presence of a suitable catalyst.
General Description
Colorless to straw-colored liquid with a mild odor. Sinks and mixes with water.
Air & Water Reactions
Water soluble.
Reactivity Profile
Bis[2-(2-hydroxyethoxy)ethyl] ether is a ether-alcohol derivative. The ether being relatively unreactive. Flammable and/or toxic gases are generated by the combination of alcohols with alkali metals, nitrides, and strong reducing agents. They react with oxoacids and carboxylic acids to form esters plus water. Oxidizing agents convert alcohols to aldehydes or ketones. Alcohols exhibit both weak acid and weak base behavior. They may initiate the polymerization of isocyanates and epoxides. May attack some forms of plastics [USCG, 1999].
Health Hazard
Compound is nonirritating. No symptoms observed by any exposure route.
Flammability and Explosibility
Nonflammable
Safety Profile
Mildly toxic by ingestion. A sktn and eye irritant. Combustible when exposed to heat or flame; can react with oxidzing materials. To fight fire, use alcohol foam, water, CO2, dry chemical. When heated to decomposition it emits acrid smoke and irritating fumes.
Check Digit Verification of cas no
The CAS Registry Mumber 112-60-7 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, 6 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 112-60:
(5*1)+(4*1)+(3*2)+(2*6)+(1*0)=27
27 % 10 = 7
So 112-60-7 is a valid CAS Registry Number.

Photocatalytic Degradation of Hexaethylene Glycol

, p. 1608 - 1614 (2017/08/29)
Abstract: Polyethylene glycol (PEG) photodegradation was studied in water under UV irradiation in the presence of catalytic amount of TiO2 using hexaethylene glycol as a model compound. Full conversion was achieved in 7 h with an average quantum yield around 1%. Formic acid was found to be the main intermediate and was slower to oxidize into CO2 (traces remains after 24 h). The other intermediates [lower PEG, oxidized PEG (formates, aldehydes and acids, acetic acid)] of the photodegradation have also been identified and quantified. A mechanism based on previous literature but also taking into account these new observations is proposed. Graphical Abstract: [Figure not available: see fulltext.].

, (2008/06/13)
This invention pertains generally to valency molecules, such as valency platform molecules which act as scaffolds to which one or more molecules may be covalently tethered to form a conjugate. More particularly, the present invention pertains to valency platform molecules which comprise a carbamate linkage (i.e., —O—C(=O)—N). In one aspect, the present invention pertains to valency platforms comprising carbamate linkages, which molecules have the structure of any one of Formulae I, II, or III, shown in FIG. 1. In one aspect, the present invention pertains to valency platforms comprising carbamate linkages, which molecules have the structure of any one of Formulae IV, V, or VI, shown in FIG. 8. The present invention also pertains to methods of preparing such valency platform molecules, conjugates comprising such valency platform molecules, and methods of preparing such conjugates.
Method for blood coagulation on hard tissues
-
, (2008/06/13)
A method of using resorbable waxes for coagulation of blood on endogenous hard tissue, especially bone, which waxes consist of waxy polyester-oligomers of hydroxybarboxylic acids which are viscous to solid at body temperature. On the basis of their structure, these waxes are degradable by endogenous metabolic mechanism, wherein the rate of degradation can be adjusted.
