Production Methods
DUP is manufactured by the reaction of phthalic anhydride
with undecanol in the presence of an acid catalyst.
Air & Water Reactions
Insoluble in water.
Reactivity Profile
Diundecyl phthalate reacts with acids to liberate heat along with alcohols and acids. Strong oxidizing acids may cause a vigorous reaction that is sufficiently exothermic to ignite the reaction products. Heat is also generated by interaction with caustic solutions. Flammable hydrogen is generated by mixing with alkali metals and hydrides. Can generate electrostatic charges [Handling Chemicals Safely, 1980. p. 250].
Fire Hazard
Diundecyl phthalate is probably combustible.
Flammability and Explosibility
Notclassified
Check Digit Verification of cas no
The CAS Registry Mumber 3648-20-2 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 3,6,4 and 8 respectively; the second part has 2 digits, 2 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 3648-20:
(6*3)+(5*6)+(4*4)+(3*8)+(2*2)+(1*0)=92
92 % 10 = 2
So 3648-20-2 is a valid CAS Registry Number.

Process for producing carboxylic acid esters and catalysts therefor
-
, (2008/06/13)
A process for producing carboxylic acid esters by the following steps: a) preparation of a reaction mixture containing an alcohol and a carboxylic acid and/or a carboxylic anhydride and/or a carboxylic acid ester and or a partially esterified carboxylic acid, b) heating of this mixture to the suitable reaction temperature in the presence of a solid polysiloxane insoluble in the reaction medium and having sulphonic acid groups with intensive thorough mixing accompanied by continuous separation of the reaction water which forms, wherein the polysiloxane used as the catalyst in modified by treatment with a soluble aluminum, titanium or zirconium compound, and the spherical particles thereof have a diameter of 0.01 to 3 mm, a specific surface of 0.1 to 1200 m2 /g, a specific pore volume of 0.01 to 6.0 ml/g and a bulk density of 50 to 1000 g/l.
