General Description
Diammonium phthalate is a chemical compound with the molecular formula (NH4)2C8H4O4. It is a salt of phthalic acid and is commonly used as a plasticizer in the production of PVC and other polymers. Diammonium phthalate is also used as a flame retardant in various applications, including textiles and electronics. It is a white, crystalline powder that is soluble in water and has a relatively low vapor pressure. The compound is not considered to be highly toxic, but prolonged exposure to high concentrations may cause irritation to the respiratory system and skin. Overall, diammonium phthalate is a versatile chemical with various industrial applications, particularly in the production of plastics and flame retardants.
Check Digit Verification of cas no
The CAS Registry Mumber 523-24-0 includes 6 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 3 digits, 5,2 and 3 respectively; the second part has 2 digits, 2 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 523-24:
(5*5)+(4*2)+(3*3)+(2*2)+(1*4)=50
50 % 10 = 0
So 523-24-0 is a valid CAS Registry Number.

Page/Page column 9, (2015/07/07)
The invention relates to a process to produce phthalimides by heating diammonium phthalate in the presence of aromatic solvents and to a process to produce phthalimides by heating diammonium phthalate in the presence of aromatic solvents for their recycled use during the ion exchanger production process. The diammonium phthalate is prepared by making use of the phthalic acid salts solution resulted from the ion exchanger production process.
