    摘要:
    本发明涉及一种以多聚甲醛二甲基醚PODEn(2≦n≦8)为原料制备双酚F的方法,其主要步骤是:酸催化条件下,苯酚与多聚甲醛二甲基醚发生羟基烷基化反应得到目标产物。上述反应在无水或者有水存在条件下均可进行。因多聚甲醛二甲基醚在苯酚和水中具有良好的溶解性,双酚F合成体系呈现为均相体系,有利于传热和传质。另外多聚甲醛二甲基醚具有定量缓释甲醛的效果,反应温和、易于控制,副反应较少,不易生成三酚和酚醛树脂等副产物,具有高收率、高选择性的优点。

  • 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。

    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.

    Polyoxymethylene dimethyl ethers (PODMEn) have been synthesized in moderate yields by the reaction of methylal (PODME1) and paraformaldehyde catalyzed by rare earth compounds. The activities of catalyst in the reaction were investigated and the results show that La3+/SO42- has a high value. The influencing factors of reaction such as catalyst amount, reaction temperature, time, pressure and mole ratio of methylal (PODME1) to paraformaldehyde were also investigated. The appropriate reaction conditions i.e., n(paraformaldehyde)/n(methylal) = 1.60, catalyst amount of 1 %, 130 °C, 6 h and 0.5 MPa. Under the above conditions, methylal conversion rate and selectivity of PODME2-8 is 81.6 and 75.5 %, respectively. In addition to, the combustion and emission characteristics of PODME2-8 added diesel was compared with the diesel, polyoxymethylene dimethyl ethers (PODME2-8) not only improved the combustion characteristics of diesel, but improved the low temperature fluidity.
    在稀土化合物的催化下,通过甲缩醛(PODME1)和多聚甲醛的反应,以中等产率合成了聚氧亚甲基二甲醚(PODMEn)。对反应中催化剂的活性进行了研究,结果表明 La3+/SO42- 的活性值较高。此外,还研究了催化剂用量、反应温度、时间、压力和甲缩醛(PODME1)与多聚甲醛的摩尔比等反应影响因素。合适的反应条件为:n(多聚甲醛)/n(甲缩醛) = 1.60、催化剂用量 1%、130 °C、6 小时和 0.5 兆帕。在上述条件下,PODME2-8 的甲缩醛转化率和选择性分别为 81.6% 和 75.5%。此外,将添加 PODME2-8 的柴油的燃烧和排放特性与柴油进行了比较,发现聚氧亚甲基二甲醚(PODME2-8)不仅改善了柴油的燃烧特性,而且提高了低温流动性。
