摘要： Provided is a method for preparing a diol. In the method, a saccharide and hydrogen as raw materials are contacted with a catalyst in water to prepare the diol. The employed catalyst is a composite catalyst comprised of a main catalyst and a cocatalyst, wherein the main catalyst is a water-insoluble acid-resistant alloy; and the cocatalyst is a soluble tungstate and/or soluble tungsten compound. The method uses an acid-resistant, inexpensive and stable alloy needless of a support as a main catalyst, and can guarantee a high yield of the diol in the case where the production cost is relatively low.

摘要： Disclosed is an acid-resisting alloy catalyst comprising nickel, one or more rare earth elements, stannum and aluminum. The acid-resistant alloy catalyst is low-cost and stable, and does not need a carrier, and can be stably used in continuous industrial production, thus achieving a low production cost.

摘要： Syrup dispensing cups are provided that include a body structure that includes a first polyester or co-polyester resin with one or more first co-monomers incorporated into the first resin at a first mol % and having an intrinsic viscosity from about 0.45 dL/g to about 1.3 dL/g when measured at a temperature of 25 C. The body structure has a first opening that is sealed with a first sealing layer and a second opening sealed with a second sealing layer, in which each sealing layer includes a second PET-based co-polyester resin having one or more second co-monomers incorporated into the second resin at a second mol %, and the ratio of the first mole % to the second mol % is less than 1. Methods for or enhancing the shelf-life of syrup dispensing cups are also provided.

摘要： This disclosure provides effective methods for expanding the processing window for poly(ethylene furanoate) (PEF) and poly(ethylene furanoate) co-polymer (PEF co-polymer) polyester preforms, such that these preforms can be beneficially used in the fabrication of bottles and containers, including bottles for carbonated soft drinks. The processing window is expanded by, for example, pre-conditioning the PEF or PEF co-polymer preform prior to stretch blow-molding by contacting the PEF or PEF co-polymer preform with water or high (>50%) relative humidity air for a desired time period and at a temperature greater than or equal to ambient temperature, to take advantage of the unique and unexpected properties afforded the preform by water sorption at these temperatures.
