Abstract: An improved pressure vessel comprising a polymer inner bladder inside a containment envelope is provided which is well-suited for transporting hazardous materials therewithin via air transport. The improved pressure vessel features a seal placed over the closure of the containment envelope which has been found to suppress failure of the pressure vessel by creep which occurs as a result of the high internal pressure that the pressure vessel experiences at high altitudes. The seal also serves to indicate whether or not the containment envelope has been tampered with after having been sealed.

Abstract: The invention herein provides a method to improve retention of tensile properties upon aging in poly(trimethylene terephthalate) cast film. The method involves first nucleating the poly(trimethylene terephthalate) resin prior to film formation and controlling the quench temperature during casting of the film. The quench temperature should be controlled to a temperature in the range of from about 10° C. below the Tg of the poly(trimethylene terephthalate) to about 15° C. above the Tg of the poly(trimethylene terephthalate).
Abstract: This invention relates to a process for producing 5-methyl-N-aryl-2-pyrrolidone, 5-methyl-N-cycloalkyl-2-pyrrolidone, and 5-methyl-N-alkyl-2-pyrrolidone by reductive amination of levulinic acid with nitro compounds utilizing a metal catalyst, which is optionally supported.

Abstract: Disclosed herein are processes for the recovery of 1,3-propanediol from an aqueous feed stream. The present invention involves contacting an aqueous feed stream that comprises water, 1,3-propanediol, and at least one contaminant with at least one solvent extractant to form a mixture. The mixture is separated into a first phase and a second phase. The second phase comprises a majority of the water from the aqueous feed stream. The first phase comprises solvent extractant and at least some of the 1,3-propanediol that was present in the aqueous feed stream. The weight ratio in the first phase of 1,3-propanediol to any one contaminant present is greater than the weight ratio of 1,3-propanediol to the same contaminant in the aqueous feed stream prior to the aqueous feed stream being contacted with the solvent extractant. The first phase can be removed from the separated second phase in order to recover the 1,3-propanediol.
