摘要： The present invention relates to a method for preparing acrylic acid, more specifically to a method for preparing acrylic acid under the neutral condition at high yield in a short time without using a base, which can be performed under the neutral condition without using the base, unlike the prior art in which base is essentially used, by producing acrylic acid using the supported catalyst having a specific composition when preparing acrylic acid by oxidation of allyl alcohol.
Particularly, the preparation method of the present invention can recover acrylic acid rather than acrylic acid salt as a final product, and thus has an advantage that the overall process cost can be reduced by eliminating essential processes in the prior art, such as ion exchange after the acidification process required for the conversion of acrylic acid salt to acrylic acid.
摘要翻译：本发明涉及一种制备丙烯酸的方法，更具体地说，涉及一种不使用碱而在短时间内在中性条件下制备丙烯酸的方法，该方法可以在不使用碱的情况下在中性条件下进行，与基本上使用碱的现有技术不同，当通过烯丙醇的氧化制备丙烯酸时，使用具有特定组成的负载型催化剂生产丙烯酸。特别地，本发明的制备方法可以回收丙烯酸而不是丙烯酸盐作为最终产物，因此具有如下优点：通过消除现有技术中的基本工艺，如离子交换之后的离子交换，可以降低整体工艺成本将丙烯酸盐转化为丙烯酸所需的酸化过程。

摘要： The present invention relates to a sealing tool for a pouch type secondary battery, which seals a pouch provided with an electrode assembly therein, the sealing tool including: a holder elevatably disposed on each of upper and lower sides of the pouch; and a sealing block coupled to the holder to contact the pouch by the elevation of the holder, thereby sealing the pouch. The sealing block and the holder are spaced apart from each other to define a space therebetween.
According to the present invention, a spacing member is interposed between the holder and the sealing block of the sealing tool to define a space into which the sealing block is deformable, thereby minimizing the deformation of a sealing surface of the sealing block. Thus, the sealing part of the pouch may have a uniform thickness to prevent an electrolyte within the pouch from leaking to the outside.

摘要： Disclosed herein are an electrode assembly including a plurality of unit cells folded by a continuous separation film wherein the unit cells are arranged on the separation film such that electrode taps of the unit cells face each other, the separation film has openings corresponding to the electrode taps of the unit cells, and the electrode assembly is manufactured by folding the unit cells in the longitudinal (lengthwise) direction of the separation film while the unit cells are disposed such that the electrode taps of the unit cells are inserted into the corresponding openings, and an electrochemical cell, such as a secondary battery, including the same. The electrode assembly according to the present invention is a hybrid type electrode assembly solving the problems of the jelly-roll type electrode assembly and the stacking type electrode assembly. Consequently, when external impacts are applied to the electrode assembly, for example, the electrode assembly falls, it is possible to minimize the occurrence of internal short circuits and thus to improve the safety of the electrode assembly. Furthermore, it is possible to perform the process for impregnating (wetting) the electrolyte into the electrodes in a short time during the assembly of the electrochemical cell.
