摘要:
Described are polyesters comprising (a) a dicarboxylic acid component comprising 2,5-furandicarboxylic acid residues; optionally, aromatic dicarboxylic acid residues and/or modifying aliphatic dicarboxylic acid residues and 1,4-cyclohexanedimethanol residues. The polyesters may be manufactured into articles such as fibers, films, bottles, coatings, or sheets.
摘要:
The invention relates to a catalyst composition comprising a mixed oxide of vanadium, titanium, and phosphorus. The titanium component is derived from a water-soluble, redox-active organo-titanium compound. The catalyst composition is highly effective at facilitating the vapor-phase condensation of formaldehyde with acetic acid to generate acrylic acid, particularly using an industrially relevant aqueous liquid feed.
摘要:
Extrusion blow molded (EBM) articles comprising a polyester having a dicarboxylic acid component and a glycol component. The dicarboxlyic acid component comprises at least 90 mole% terephthal- ic acid residues. The glycol component comprises at least 88 mole% ethylene glycol residues and 7 to 12 mole% residues of 1,4-cyclohexanedimethanol. Such EBM articles can exhibit reduced haze, reduced sharkskin, and/or increased compatibility in PET recycling.
摘要:
Disclosed is a process for the preparation of 1,4-cyclohexanedimethanol from terephthalic acid. Terephthalic acid is esterified with (4-methylcyclohexyl)methanol and the terephthalate ester hydrogenated to 1,4-cyclohexanedimethanol in a 2-stage process. The (4-methylcyclohexyl)methanol that is formed during the hydrogenation step is recycled to the esterification reaction. After removal of the (4- methylcyclohexyl)methanol from the crude hydrogenation product, the 1,4- cyclohexanedimethanol product can be recovered and purified by a phase separation and distillation.
