Answer:
Concept:
The chemical substance with the formula C6H4(CO)2O is phthalic anhydride. It is phthalic acid's anhydride. The main commercial form of phthalic acid is phthalic anhydride. It was the first commercially used dicarboxylic acid anhydride. This white solid is an essential industrial chemical, especially in the production of plasticizers on a large scale. Around 3 million tonnes were thought to be produced worldwide annually in 2000.

Answer:
White Lustrous Crystals With a Particular Smell a colourless to white, glossy substance that resembles needles and has a light, distinguishing smell.
Phthalic anhydride appears as a needle-shaped, colourless to white, glossy solid with a faintly distinguishing odour. By eating or inhalation, it is moderately harmful, and it irritates the skin. Flash point 305°F Melting point 64°F corrosive solution is created when combined with water. used in the production of materials like synthetic resins.
The cyclic dicarboxylic anhydride of phthalic acid is called phthalic anhydride. It plays the part of an allergy. It is a 2-benzofuran and cyclic dicarboxylic anhydride.
Phthalic anhydride exposure could result from its use as a chemical intermediary in the plastics sector. Humans who have been exposed to phthalic anhydride experience irritation of the eyes, respiratory system, and skin, but no long-term damage is seen. Workers exposed to phthalic anhydride experienced bronchitis, and irritation of the skin and respiratory tract mucous membranes as chronic (long-term) symptoms. Studies on animals show that long-term inhalation of phthalic anhydride vapour damages lung cells by congesting, irritating, and swelling them. There are no research on the impact of phthalic anhydride on human reproduction, development, or cancer. Phthalic anhydride has not been designated as carcinogenic by the EPA.
