Reactivity Profile
ETHYLENE GLYCOL DI-N-BUTYL ETHER may react violently with strong oxidizing agents. May generate flammable and/or toxic gases with alkali metals, nitrides, and other strong reducing agents. May initiate the polymerization of isocyanates and epoxides. Relatively inert in other reactions, which typically involve the breaking of the carbon-oxygen bond.
Health Hazard
Moderately toxic by ingestion and skin contact. Irritates skin and eyes.
Fire Hazard
Special Hazards of Combustion Products: On decomposition, ETHYLENE GLYCOL DI-N-BUTYL ETHER emits acrid smoke and irritating fumes.
Purification Methods
Shake the ether with aqueous 5% Na2CO3, dry with MgSO4 and store it with chromatographic alumina to prevent peroxide formation. [Beilstein 1 III 2083, 1 IV 2382.]
Check Digit Verification of cas no
The CAS Registry Mumber 112-48-1 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, 4 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 112-48:
(5*1)+(4*1)+(3*2)+(2*4)+(1*8)=31
31 % 10 = 1
So 112-48-1 is a valid CAS Registry Number.

Preparation method for double-terminated glycol ether
-
Paragraph 0049; 0062; 0063, (2017/07/25)
The invention relates to a preparation method for double-terminated glycol ether. The preparation method comprises a step of introducing raw materials containing glycol monoether and monohydric ether alcohol into a reactor for contact and reaction with an acidic molecular sieve catalyst so as to produce double-terminated glycol ether, wherein reaction temperature is 50 to 300 DEG C, reaction pressure is 0.1 to 15 MPa, the mass space velocity of the glycol monoether in the raw materials is 0.01 to 15.0/h, and a mol ratio of monohydric ether alcohol to glycol monoether in the raw materials is 1-100: 1. The preparation method has the advantages that the catalyst has long single-pass life and can be repeatedly regenerated; the target product, i.e., double-terminated glycol ether has high yield and selectivity; energy consumption in separation of products is low; by-products have high economic value; production scale can be large or small; and application of the method is flexible.
