action between glycerol and phthalic acid. The molecular structure of the polyesters is strongly influenced by the molar ratio between the monomers. An equimolar mixture of glycerol and phthalic acid should produce polyester with alcohols group, even if the esterifica-tion proceeds in quantitative yield. Therefore, the polyester POLF I

Resins made with phthalic anhydride can be practically cooked up to only a relatively modest molecular weight before decarboxylation by loss of PA places a practical limit on the extent of condensation. Ortho-phthalic based unsaturated polyester alkyds will generally be condensed to (by GPC) 800 to 1,000 number average molecular weights.

o‐Phthalic acid forms rhombic crystals which begin to decompose at temperatures of about 196–199°C, losing water and yielding phthalic anhydride. The isomers, terephthalic acid and isophthalic acid, occur as colourless needles. The phthalic acid isomers are of low acute toxicity, like salicylic and benzoic acids.
Here limiting reagent is phthalic anhydride; hence yield should be calculated from its amount. Molecular formula of phthalic anhydride = C 8 H 4 O 3. Molecular formula of anthranilic acid = C 7 H 7 NO 2. Molecular weight of phthalic anhydride = 148 g/mole. Molecular weight of anthranilic acid = 137 g/mole. Theoretical yield:

Phthalic acid is an aromatic dicarboxylic acid, with formula C6H4(COOH)2. Phthalic acid is used mainly in the form of the anhydride to produce other chemicals such as dyes, perfumes, saccharin, phthalates and many other useful products. Phthalic acid, when found in tissues or biofluids arises from exposure to these phthalate products.
Phthalic anhydride is a principal commercial form of phthalic acid. It was the first anhydride of a dicarboxylic acid to be used commercially. This white solid is an important industrial chemical, especially for the large-scale production of plasticizers for plastics.
Phthalic anhydride is the organic compound with the formula C 6 H 4 (CO) 2 O. It is the anhydride of phthalic acid. Phthalic anhydride is a principal commercial form of phthalic acid. It was the first anhydride of a dicarboxylic acid to be used commercially.
Urine was also taken from a control group of 22 persons not occupational exposed to phthalic anhydride. Phthalic anhydride is converted to phthalic acid in the presence of water. Phthalic acid concentration in the urine was measured after esterification with methanol by electron capture gas chromatography, and expressed in terms of urinary creatinine. Urine samples were also subjected to …

PHTHALIC ACID is a carboxylic acid. This chemical is sensitive to exposure to extreme heat. This compound reacts violently with nitric acid. It is incompatible with sodium nitrite. It is also incompatible with oxidizers. (NTP, 1992).
I need help finding the molar mass to get the molecular formula. Terephthalic acid is an important chemical used in the manufacture . asked by sean P. on April 25, 2010; Chemistry [sumone help me please :(] 0.250g of phthalic acid is dissolved in 40.00cm^3 of 0.100 mol dm^-3 NaOH.
Terephthalic acid is one isomer of the three phthalic acids. It finds important use as a commodity chemical, principally as a starting compound for the manufacture of polyester (specifically PET), used in clothing and to make plastic bottles. It is also known as 1, 4-benzenedicarboxylic acid, and it has the chemical formula C6H4(COOH)2. -- Wikipedia.
