117-83-9 Usage
Chemical Properties
The empirical formula of dibutoxyethyl phthalate (DBEP) is
C20H30O6. It is a colorless liquid, with a density
of 1.063.It is soluble in organic solvents and fairly
insoluble in water.
Uses
It is used as a plasticizer for polyvinyl
chloride, polyvinyl acetate, and other resins.
Definition
ChEBI: A phthalate ester obtained by the formal condensation of both the carboxy groups of phthalic acid with two molecules of 2-butoxyethanol.
Production Methods
DBEP is formed by the esterification of glycol monobutyl
ether with phthalic anhydride in the presence of a catalyst
(sulfuric acid or p-toluenesulfonic acid) or noncatalytically
at high temperature.
Safety Profile
Mildly toxic by ingestion. Whenheated to decomposition it emits acrid smoke andirritating fumes.
Check Digit Verification of cas no
The CAS Registry Mumber 117-83-9 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 7 respectively; the second part has 2 digits, 8 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 117-83:
(5*1)+(4*1)+(3*7)+(2*8)+(1*3)=49
49 % 10 = 9
So 117-83-9 is a valid CAS Registry Number.
