    摘要： This invention provides a process a process for recovering terephthalic acid from pulverized products of spent polyethylene terephthalate. This process comprises (1) a decomposition reaction step where the pulverized products of spent polyethylene terephthalate are continuously subjected to decomposition reaction in ethylene glycol in the presence of alkali, which is equimolar or excessmolar relative to the polyethylene terephthalate, so that salt of terephthalic acid and ethylene glycol can be continuously obtained; (2) a solid-liquid separation, dissolution, impurities-removing step where the ethylene glycol is separated from decomposition reaction slurry of salt of terephthalic acid and ethylene glycol, and the solid salt of terephthalic acid is dissolved into water, while insoluble impurities are removed; (3) a neutralization, crystallization step, where solution of said salt of terephthalic acid is neutralized with acid so that terephthalic acid can be crystallized; (4) a solid-liquid separation, washing step where slurry of terephthalic acid crystals is subjected to solid-liquid separation so that the terephthalic acid crystals can be obtained and washed; and (5) a drying, pulverization step where the washed terephthalic acid crystals are dried and pulverized.

    摘要： An improved liquid transfusing bottle made of flexible material of the type using no air venting needle. It includes a barrel portion, a shoulder portion and a bottom portion and parting lines extend on both the side faces in the vertical direction. The barrel portion is formed with ribs or recessed area of which contour line is so designed that a distance as measured from the parting line decreases toward the center part of the bottle from the shoulder portion or the bottom portion. As a residual volume of liquid in the bottle decreases, the barrel portion is deformed in the flattened configuration along the contour lines of the ribs or the recessed parts in such a manner that the shorter diameter thereof is reduced. Deformation of the barrel portion is achieved without any occurrence of twisting, breaking or the like of the bottle and liquid in the bottle is smoothly discharged therefrom at a constant speed during operation of transfusion.

    摘要： In a thermoplastic polyester, a compound having at least two ethylenically unsaturated groups and/or oxirane rings in one molecule is coated as a crosslinking agent on the outer surface of the polyester substrate, or a polyester composition containing this crosslinking agent is laminated on the polyester substrate as the inner surface layer, and the crosslinking agent or the crosslinking agent-containing polyester composition is irradiated with ionizing radiant rays or ultraviolet rays. In this processed vessel, the dimension stability and rigidity are highly improved, and deformation under heat and/or pressure can be effectively prevented.
