2287-83-4 Usage
General Description
ITACONIC ACID DI(2-ETHYLHEXYL) ESTER is an organic compound that is derived from itaconic acid and 2-ethylhexanol. It is commonly used as a plasticizer in the production of polymers, resins, and adhesives to improve flexibility and durability. It is also used as a raw material in the synthesis of various industrial chemicals, including lubricants, surfactants, and coatings. Due to its low toxicity and environmental friendliness, ITACONIC ACID DI(2-ETHYLHEXYL) ESTER is widely used in the manufacturing of consumer products such as food packaging, medical devices, and consumer electronics.
Check Digit Verification of cas no
The CAS Registry Mumber 2287-83-4 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 2,2,8 and 7 respectively; the second part has 2 digits, 8 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 2287-83:
(6*2)+(5*2)+(4*8)+(3*7)+(2*8)+(1*3)=94
94 % 10 = 4
So 2287-83-4 is a valid CAS Registry Number.

A series of itaconate esters, e.g. dimethyl itaconate, dibutyl itaconate and diisooctyl itaconate, were synthesized using solid acid SO4 2-/MxOy (M = Ti4+, Fe3+, Zr4+, Al3+) and SO42-/TiO2-SiO2 modified with lanthanide ion (Ln = La3+, Ce4+, Sm 3+) as catalysts. It was found that SO4 2-/TiO2-SiO2 modified with lanthanide ion were of the same excellent catalytic activity as sulfuric acid (H2SO 4). Moreover, Ln～SO42-/TiO 2-SiO2 is of excellent stability. Take La 3+～SO42-/TiO2-SiO2 for example, the influence of the preparation conditions on catalytic performance was in detail examined by Py-FTIR, NH3-FTIR, XRD and NH3-TPD, and the optimum preparation conditions were obtained. Furthermore, the effective separation of product combined with the recyclable catalyst is expected to contribute to the development of clean and environmental friendly strategy for the synthesis of itaconate esters.
