  The present invention relates to a method for producing a furan-based compound using an ion exchange resin in the presence of an organic solvent. In the method for producing a furan-based compound according to the present invention, a furan-based compound is made from an aldose-type hexose compound in the presence of an organic solvent by using an anion exchange resin and a cation exchange resin. Thus, the aldose-type hexose compound obtained from biomass by simultaneously or consecutively using the anion/cation exchange resins as catalysts can be made into 5-hydroxymethyl-2-furfural (HMF) or alkyl ether derivatives thereof such as 5-alkoxymethyl-2- furfural (AMF) without using an expensive reagent. Also, since the selection of an organic solvent is not limitative and a heterogeneous catalyst can be used, separation and purification is easy and chemically stable AMF can be directly obtained. Further, the conversion efficiency of the aldose-type hexose compound is excellent, and the hexose compound can be used at a high concentration.

  本发明涉及一种在有机溶剂存在下使用离子交换树脂生产呋喃类化合物的方法。在根据本发明生产呋喃类化合物的方法中，通过使用阴离子交换树脂和阳离子交换树脂，在有机溶剂存在下从醛糖类己糖化合物制得呋喃类化合物。因此，同时或连续使用阴/阳离子交换树脂作为催化剂从生物质中获得的醛糖类己糖化合物，无需使用昂贵的试剂即可制成 5-羟甲基-2-糠醛（HMF）或其烷基醚衍生物，如 5-烷氧基甲基-2-糠醛（AMF）。此外，由于有机溶剂的选择不受限制，而且可以使用异相催化剂，因此分离和纯化非常容易，可以直接获得化学性质稳定的 AMF。此外，醛糖型己糖化合物的转化效率极高，而且可以高浓度使用己糖化合物。

  Provided herein is a method for producing 5-hydroxymethyl-2-furfural (HMF) from maize syrup containing fructose including a conversion step in which a reaction product containing the 5-hydroxymethyl-2-furfural is produced by mixing and heating the maize syrup, a dioxane solvent and a solid acid catalyst, thus providing an advantage that the solvent can be easily isolated and the isolated solvent can be reused because dioxane is used as the solvent, and an advantage that the catalyst can be easily isolated and the isolated catalyst can be easily reused because a nonuniform solid acid catalyst is used.

  本发明提供了一种从含有果糖的玉米糖浆中生产 5-羟甲基-2-糠醛（HMF）的方法，该方法包括一个转化步骤，在该步骤中，通过混合和加热玉米糖浆、二噁烷溶剂和固体酸催化剂，生成含有 5-羟甲基-2-糠醛的反应产物、由于使用二恶烷作为溶剂，因此具有易于分离溶剂和分离的溶剂可重复使用的优点；由于使用不均匀的固体酸催化剂，因此具有易于分离催化剂和分离的催化剂可重复使用的优点。

  The invention relates to a cap (300B) for an attenuated total reflectance infrared (ATR-IR) spectrometer, the ATR-IR spectrometer comprising an ATR-IR plate (200). The cap (300B) comprises an ATR- IR plate facing cap surface. When the ATR-IR plate facing cap surface is placed on the sample surface side of the ATR-IR plate (200), a sample cavity enclosing the sample is formed between the sample surface side of the ATR-IR plate (200) and the ATR-IR plate facing cap surface of the cap (300B). This sample cavity can be an air tight cavity. The cap may further comprise a bridge (322), which functions as cap securing means (322), as the cap (300B) is secured onto the ATR-IR plate (200) by a pressure clamp (108) and an arm (110) holding the pressure clamp (108) pressing on the bridge (322)..
