112-73-2 Usage
Chemical Properties
clear colorless to yellowish liquid
Uses
Different sources of media describe the Uses of 112-73-2 differently. You can refer to the following data:
1. Butyl diglyme is used to extract gold from
hydrochloric acid solutions containing other metals. Treatment of the diglyme
extract with hydrogen or oxalic acid precipitates the ionic gold as gold powder.
2. Extraction of precious metalsDiethylene glycol dibutyl ether is used as a solvent in Grignard reactions. It is also used as solvents in gold refining, decorative inks for ceramics and digital inks. It finds application in electrochemistry, gas absorption, extractant and high boiling reaction medium. It is also used in fuel, lubricant, textile and medicine.
Reactivity Profile
Bis(2-butoxyethyl)ether may react violently with strong oxidizing agents. Incompatible with nitric acid. May form salts with strong acids and addition complexes with Lewis acids. In other reactions, which typically involve the breaking of the carbon-oxygen bond, relatively inert.
Health Hazard
May be harmful by inhalation, ingestion and skin absorption. Causes eye and skin irritation. Material is irritating to mucous membrane and upper respiratory tract.
Flammability and Explosibility
Nonflammable
Safety Profile
Moderately toxic by
ingestion. Mddly toxic by skin contact.
Experimental reproductive effects. A skin
and eye irritant. See also GLYCOL
ETHERS. Combustible when exposed to
heat or flame. To fight fire, use foam or
alcohol foam. When heated to decomposition it emits acrid smoke and
irritating fumes.
Purification Methods
Dibutylcarbitol is freed from peroxides by slow passage through a column of activated alumina. The eluate is then shaken with Na2CO3 (to remove any remaining acidic impurities), washed with water, and stored with CaCl2 in a dark bottle [Tuck J Chem Soc 3202 1957]. [Beilstein 1 IV 2395.]
Check Digit Verification of cas no
The CAS Registry Mumber 112-73-2 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, 7 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 112-73:
(5*1)+(4*1)+(3*2)+(2*7)+(1*3)=32
32 % 10 = 2
So 112-73-2 is a valid CAS Registry Number.

Process for the preparation of cyclic esters and method for purification of the same
-
Page/Page column 11, (2010/11/30)
The present invention provides a process for production of a cyclic ester by depolymerization of an aliphatic polyester. In the process, a mixture containing the aliphatic polyester and a specific polyalkylene glycol ether, which has a boiling point of 230-450° C. and a molecular weight of 150-450, is heated under normal or reduced pressure to a temperature at which depolymerization of the aliphatic polyester takes place. Then, a substantially homogeneous solution phase, consisting of the melt phase of the aliphatic polyester and the liquid phase of the polyalkylene glycol ether, is formed. Heating of the solution phase is continued to form the cyclic ester by depolymerization and distil out the cyclic ester together with the polyalkylene glycol ether, and then the cyclic ester is recovered from the distillate. The present invention also provides a process for purification of a crude cyclic ester by use of the specific polyalkylene glycol ether described above.
