68515-43-5 Usage
Chemical Properties
Di-C9-11 phthalate (D911P) is a mixture of C9 and C11
esters of phthalic acid where different alcohols can be
esterified to the same molecule of phthalic acid. It is a
colorless, oily liquid. D911P is only minimally
soluble in water (＜0.1 mg/L). It has a neutral pH value.
Uses
D911P is used as a
plasticizer in vinyl formulations. Major end uses
include automotive vinyl, film, sheeting, and industrial
vinyl sealant.
Production Methods
D911P is commercially produced by catalyzed esterification
of phthalic anhydride with C9-11 alcohol blend utilizing
batch or continuous processes. The individual process steps
consist of a reaction step, excess alcohol removal,
drying, and filtration. The final product has a phthalate
ester content of well above 99.5%.
Flammability and Explosibility
Nonflammable
Check Digit Verification of cas no
The CAS Registry Mumber 68515-43-5 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 6,8,5,1 and 5 respectively; the second part has 2 digits, 4 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 68515-43:
(7*6)+(6*8)+(5*5)+(4*1)+(3*5)+(2*4)+(1*3)=145
145 % 10 = 5
So 68515-43-5 is a valid CAS Registry Number.
