Further, TBBPA structurally mimics the thyroid hormone thyroxin (T 4) and can bind more strongly to the transport protein transthyretin than T 4 does, likely interfering with normal T 4 activity. TBBPA likely also suppresses immune responses by inhibiting expression of CD25 receptors on T cells , preventing their activation, and by reducing ...
Epichlorohydrin (abbreviated ECH) is an organochlorine compound and an epoxide. Despite its name, it is not a halohydrin . It is a colorless liquid with a pungent, garlic-like odor, moderately soluble in water, but miscible with most polar organic solvents . [ 4 ]
Bisphenol A (BPA) is a chemical compound primarily used in the manufacturing of various plastics.It is a colourless solid which is soluble in most common organic solvents, but has very poor solubility in water.
The bisphenols (/ ˈ b ɪ s f ɪ n ɒ l /) are a group of industrial chemical compounds related to diphenylmethane; commonly used in the creation of plastics and epoxy resins. [1] [2] [3] Most are based on two hydroxyphenyl functional groups linked by a methylene bridge.
HOC 6 H 4 CH 2 OH + HOC 6 H 5 → (HOC 6 H 4) 2 CH 2 + H 2 O 2 HOC 6 H 4 CH 2 OH → (HOC 6 H 4 CH 2) 2 O + H 2 O. The diphenol (HOC 6 H 4) 2 CH 2 (sometimes called a "dimer") is called bisphenol F, which is an important monomer in the production of epoxy resins. Bisphenol-F can further link generating tri- and tetra-and higher phenol oligomers.
Bisphenol A diglycidyl ether slowly hydrolyzes to 2,2-bis[4(2,3-dihydroxypropoxy)phenyl)propane (bis-HPPP). Similarly, DGEBA reacts with acrylic acid to give vinyl ester resins . The reaction results in opening of the epoxide ring, generating unsaturated esters at each terminus of the molecule.
AGE is prepared commercially by the etherification of allyl alcohol with epichlorohydrin. Hydrogen chloride, the byproduct of their condensation, is removed with a base. [5] The synthesis of allyl glycidyl ether by condensation of allyl alcohol and epichlorohydrin. AGE can also be synthesized by monoepoxidation of diallyl ether. [6] [7]
4-Isopropylphenol is an organic compound with the formula (CH 3) 2 CHC 6 H 4 OH. The molecule consists of an isopropyl group affixed to the para ( p -) position of phenol . The compound, a white solid, is produced by the alkylation of phenol with propylene and is relevant to the production of the commodity chemical bisphenol A (BPA).
