Is phthalic acid soluble in hexane?
The solubility of phthalic anhydride was measured at 283-313 K under atmospheric pressure in ethyl acetate, n-propyl acetate, methyl acetate, acetone, 1,4-dioxane, n-hexane, n-butyl acetate, cyclohexane, and dichloromethane. The solubility of phthalic anhydride in all solvents increased with the increasing temperature.
Is phthalic acid soluble in ether?
Alfa Aesar™ Phthalic acid, 99% It serves as an organic reagent in the production of phthalates. It is used to prepare 1,3-cyclohexadiene by reduction using sodium amalgam. Soluble in water, alcohol and etherSoluble in alcohol. Slightly soluble in water, methanol and ether.
What is the melting point of phthalic acid?
^ Several melting points are reported, for example: (i) 480. K (NIST website), (ii) 210−211 °C with decomposition (Sigma-Aldrich on-line), (iii) 191 °C in a sealed tube (Ullmann's Encyclopedia of Industrial Chemistry), (iv) 230 °C with conversion to phthalic anhydride and water (J.T.Baker MSDS).
Which is the most toxic form of phthalic acid?
Typically phthalate esters are prepared from the widely available phthalic anhydride. Reduction of phthalic acid with sodium amalgam in the presence of water gives the 1,3-cyclohexadiene derivative. The toxicity of phthalic acid is low with LD 50 (mouse) of 550 mg/kg. The bacteria Pseudomonas sp. P1 degrades phthalic acid.
Which is an isomer of isophthalic acid?
Phthalic acid. Phthalic acid is an aromatic dicarboxylic acid, with formula C 6 H 4 (CO 2 H) 2. It is an isomer of isophthalic acid and terephthalic acid. Although phthalic acid is of modest commercial importance, the closely related derivative phthalic anhydride is a commodity chemical produced on a large scale.
Which is the best way to reduce phthalic acid?
Reduction of phthalic acid with sodium amalgam in the presence of water gives the 1,3-cyclohexadiene derivative. The toxicity of phthalic acid is low with LD 50 (mouse) of 550 mg/kg. The bacteria Pseudomonas sp. P1 degrades phthalic acid.
