  • Towards a Sustainable Synthesis of Oxymethylene Dimethyl Ether by Homogeneous Catalysis and Uptake of Molecular Formaldehyde

    Catalyzed by trimethyloxonium salts, dimethoxymethane takes up monomeric gaseous formaldehyde instantaneously and forms high purity OMEn at temperatures of 25–30 °C. This new anhydrous approach using molecular formaldehyde and catalytic amounts of highly active trimethyloxonium salts represents a promising new step towards a sustainable formation of OMEn emanating from CO2 and H2.
    甲醛二甲基醚(OME n ; CH 3(-OCH 2-)n O-CH 3,n = 3-5)是一类新型的可持续合成燃料,由于其无烟燃烧而引起了越来越多的关注。本文提出了一种新颖的无水OME n合成路线。在三甲基氧鎓盐的催化下,二甲氧基甲烷瞬间吸收单体气态甲醛,并在25–30°C的温度下形成高纯度的OME n。这种使用分子甲醛和催化量的高活性三甲基氧鎓盐的无水新方法代表了可持续形成OME n的有希望的新步骤源于CO 2和H 2。
  • Rhenium oxide-modified H<sub>3</sub>PW<sub>12</sub>O<sub>40</sub>/TiO<sub>2</sub>catalysts for selective oxidation of dimethyl ether to dimethoxy dimethyl ether

    日期:——
    An efficient rhenium oxide-modified H3PW12O40/TiO2 catalyst is found for a new synthesis of dimethoxy dimethyl ether from dimethyl ether oxidation. The effects of Re loading, H3PW12O40 content and different feedstocks on the performance of Re–H3PW12O40/TiO2 were investigated. The results showed that DMM2 selectivity was significantly improved up to 60.0%, with 15.6% of DME conversion over 5% Re–20% H3PW12O40/TiO2. NH3-TPD, NH3-IR, Raman spectra, H2-TPR, XPS and TEM were used to extensively characterize the structure and surface properties of the catalysts. The introduction of H3PW12O40 significantly affected the structure and reducibility of surface rhenium oxide species, in addition to increasing the acidity of the catalyst. The increased number of Lewis acid sites and weak acid sites and the optimal ratio of Re4+/Re7+ of Re–H3PW12O40/TiO2 were favorable for the formation of DMM2 from DME oxidation. The possible reaction pathway of DME oxidation to DMM2 was proposed.
    发现了一种高效的铼氧化物修饰的H3PW12O40/TiO2催化剂,可用于从二甲醚氧化合成二甲氧基二甲醚。研究了铼负载量、H3PW12O40含量及不同原料对Re–H3PW12O40/TiO2催化剂性能的影响。结果显示,5% Re–20% H3PW12O40/TiO2催化剂的二甲醚转化率为15.6%,而DMM2选择性显著提高至60.0%。研究使用了NH3-TPD、NH3-IR、拉曼光谱、H2-TPR、XPS和TEM等方法对催化剂的结构和表面特性进行了广泛表征。H3PW12O40的引入显著影响了表面铼氧化物物种的结构和可还原性,同时增加了催化剂的酸度。Lewis酸位点和弱酸位点的数量增加,以及Re–H3PW12O40/TiO2中Re4+/Re7+的最佳比率,有利于二甲醚氧化生成DMM2。提出了二甲醚氧化生成DMM2的可能反应路径。

    The invention relates to a reaction system and process for continuously preparing polymethoxy dimethyl ether (DMM 3-8 ) by a continuous acetalization reaction between an aqueous formaldehyde solution or paraformaldehyde and methanol in the presence of a functionalized acidic ionic liquid as a catalyst. The reaction system of the invention preferably comprises a formaldehyde-concentrating unit, a vacuum-drying unit, an acetalization reaction unit, a product-separating unit and a catalyst-regenerating unit. The process of the invention uses aqueous formaldehyde solution as an initial raw material, which is concentrated in the formaldehyde-concentrating unit to a concentrated formaldehyde of 50˜80 wt. %, and vacuum-dried to paraformaldehyde, or uses paraformaldehyde as raw material directly, then obtains DMM 3-8 by an acetalization reaction. The raw materials of the reaction used in the invention are cheap and available easily, and the utilization rate of formaldehyde is high; an efficient separation between the catalyst and product, as well as the reuse of the catalyst and raw materials, are realized by a separation mode of combining extraction and rectification together.
