1,3-Benzenedicarboxylic acid, bis[4-(chlorocarbonyl)phenyl] ester, also known as terephthalic acid bis(4-chlorocarbonylphenyl) ester, is a complex organic compound with the chemical formula C18H10Cl2O6. It is a derivative of terephthalic acid, where two 4-chlorocarbonylphenyl groups are esterified to the carboxylic acid groups of the benzene ring. 1,3-Benzenedicarboxylic acid, bis[4-(chlorocarbonyl)phenyl] ester is an important intermediate in the synthesis of various polymers, particularly polyesters, and is used in the production of polyethylene terephthalate (PET), a widely used plastic material. The presence of the chlorocarbonyl group allows for further chemical reactions, making it a versatile building block in the chemical industry.

96123-43-2 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 96123-43-2 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 9,6,1,2 and 3 respectively; the second part has 2 digits, 4 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 96123-43:
(7*9)+(6*6)+(5*1)+(4*2)+(3*3)+(2*4)+(1*3)=132
132 % 10 = 2
So 96123-43-2 is a valid CAS Registry Number.

Poly(1,3,4-oxadiazole-ester-amide)s

Sava, Ion,Iosip, Mariana-Dana,Bruma, Maria

, p. 515 - 523 (2007/10/03)

New aromatic poly (1,3,4-oxadiazole)s containing both amide and ester groups in the main chain have been synthesized and their properties have been determined and compared with those of wholly aromatic polyamides and poly(1,3,4-oxadiazole)s. These polymers show good thermal stability, with the initial decomposition temperature around 360°C and the glass transition temperature in the range 190°C-270°C. They are easily soluble in certain solvents such as N-methylpyrrolidinone, N,N′-dimethylacetamide and N,N′-dimethylformamide, and can be cast from solutions into thin flexible films.

Fluorinated poly(benzoxazole-ester)s

Sava, Ion,Hamciuc, Corneliu,Bruma, Maria,Hamciuc, Elena

, p. 1161 - 1166 (2007/10/03)

New poly(benzoxazole-ester)s were prepared by polycondensation of bis(o-aminophenol), such as 2,2-bis(3-amino-4-hydroxyphenyl)hexafluoropropane, with diacid chlorides containing ester groups. The soluble polymer precursor resulting from the first step of polycondensation in N-methylpyrrolidinone (NMP) at low temperature was processed into thin flexible films, which were then thermally treated to reach the fully cyclized structure of poly(benzoxazole-ester)s, as observed by infrared spectra.

Aromatic polyesters containing heterocyclic units

Hamciuc, Elena,Hamciuc, Corneliu,Sava, Ion,Belomoina, Natalyia M.,Brumǎ, Maria

, p. 327 - 333 (2007/10/03)

Aromatic poly(phenylquinoxaline-esters) have been synthesized by solution polycondensation of bis(hydroxyphenylquinoxaline)s with two diacid chlorides containing preformed ester units. Also, poly(phenylquinoxaline-esters) containing pendent imide rings have been synthesized by the same procedure using bis(hydroxyphenylquinoxalines) and two diacid chlorides containing preformed imide rings. All these polymers were characterized by infrared spectra, elemental analysis, viscometric measurements and thermogravimetric data.
