Aryl-containing Carboxylic Acid Or Derivative Of An Aryl-containing Dicarboxylic Acid Patents (Class 528/308)
  • Patent number: 11993708
    Abstract: Blends comprising an aromatic polyester polyol and a 1 to 10 wt. % of a fatty acid derivative are disclosed. The fatty acid derivative is a C8 to C18 fatty acid ester or a C8 to C18 fatty acid amide. Also disclosed are rigid PU or PU-PIR foams that comprise a reaction product of water, a catalyst, a foam-stabilizing surfactant, a polyisocyanate, a blowing agent, and the polyester polyol/fatty acid derivative blends. Surprisingly, low-temperature R-values of rigid foams based on pentane blowing agents can be improved significantly by using blends of aromatic polyester polyols and a minor proportion of readily available fatty acid derivatives. In some aspects, the difference between initial R-values of the foam measured at 75° F. and 40° F. is at least 5% greater than that of a similar foam prepared in the absence of the fatty acid derivative.

    Abstract: Disclosed are processes and systems for manufacturing polyethylene terephthalate (PET) and pre-polymer. The processes and systems use a variable pressure drop up-flow-pre-polymerizer configuration. The pressure profile in the UFPP can be selected to beneficially change the relative reaction rates of the polymerization and esterification reactions. This design maximizes the esterification carried out in the UFPP, while still producing a pre-polymer with the optimum carboxyl end groups concentration (e.g., about 30? equiv./g to 60? equiv./g) to maximize finisher productivity. This can result in a reduction of the size and cost of the esterifier required for a given plant throughput.
