  • Fluoride-free and low concentration template synthesis of hierarchical Sn-Beta zeolites: efficient catalysts for conversion of glucose to alkyl lactate
    作者:Xiaomei Yang、Jingjing Bian、Jianhao Huang、Weiwen Xin、Tianliang Lu、Chen Chen、Yunlai Su、Lipeng Zhou、Feng Wang、Jie Xu

    Hierarchical Sn-Beta was prepared by a hydrothermal postsynthesis method. It shows higher catalytic activity for conversion of glucose to alkyl lactate than microporous Sn-Beta hydrothermally synthesized in fluoride media.

    采用水热后合成法制备了分级Sn-Beta催化剂。与在氟化物介质中水热合成的微孔Sn-Beta相比,它对葡萄糖转化为烷基乳酸的催化活性更高。
  • Brønsted acid ionic liquid catalyzed formation of pyruvaldehyde dimethylacetal from triose sugars
    作者:Shunmugavel Saravanamurugan、Anders Riisager
    DOI:10.1016/j.cattod.2012.07.001
    日期:2013.2
    A series of sulfonic acid functionalized ionic liquids (SO3H-ILs) have been synthesized, characterized and investigated as catalysts for the conversion of the triose sugars, 1,3-dihydroxyacetone (DHA) and glyceraldehyde (GLA), to pyruvaldehyde dimethylacetal (PADA) in methanol. Depending on the reaction conditions and the applied SO3H-ILs a good yield of up to 52% of PADA was obtained. Under identical
    合成,表征和研究了一系列磺酸官能化的离子液体(SO 3 H-ILs),作为将三糖,1,3-二羟基丙酮(DHA)和甘油醛(GLA)转化为丙酮醛二甲基缩醛( PADA)在甲醇中。取决于反应条件和所施加的SO 3 H-IL,获得高达52%的PADA的良好产率。在相同的反应条件下,使用另一种SO 3 H-IL可获得高达49%的PADA衍生物1,1,2,2-四甲氧基丙烷(TMP)。
  • Stereochemical aspects of the formation of diastereoisomeric 3-acetyl-2-(polyacetoxyalkyl)-5-phenyl-2,3-dihydro-1,3,4-oxadiazoles

  • Tin-catalyzed conversion of trioses to alkyl lactates in alcohol solution
    作者:Yukiko Hayashi、Yoshiyuki Sasaki
    DOI:10.1039/b501964h
    日期:——
    Tin chlorides, SnCl2 and SnCl4.5H2O are excellent catalysts for the reactions of trioses, dihydroxyacetone and glyceraldehyde with alcohols (MeOH, EtOH and nBuOH) to give alkyl lactates, whose reaction mechanism involves the intermediary formation of pyruvic aldehyde followed by its esterification, which is distinctively promoted by tin halides.
    氯化锡,SnCl2和SnCl4.5H2O是三糖,二羟基丙酮和甘油醛与醇(MeOH,EtOH和nBuOH)反应生成乳酸烷基酯的极佳催化剂,其反应机理涉及丙酮醛的中间形成,然后进行酯化,由卤化锡显着促进。
  • Reactions of alcohols with α-alkoxyacroleins at room temperature
    作者:N. A. Keiko、Yu. A. Chuvashev、L. G. Stepanova、M. G. Voronkov

    日期:1998.12
    medium at 20°C under kinetically controlled conditions is the Markovnikoff addition at the C=C bond to form 2,2-dialkoxypropanals (methylglyoxal ketals). Under conditions of thermodynamic control, subsequent acetalization of the aldehyde group occurs to form 1,1,2,2-tetraalkoxypropanes. When the duration of the reaction is further increased in the absence of a water acceptor, the ketal group undegroes hydrolysis
    醇与 α-烷氧基丙烯醛在酸性介质中在动力学控制条件下于 20°C 反应的第一阶段是在 C=C 键上进行马尔可夫尼科夫加成以形成 2,2-二烷氧基丙醛(甲基乙二醛缩酮)。在热力学控制条件下,醛基随后发生缩醛化以形成 1,1,2,2-四烷氧基丙烷。当在不存在水受体的情况下进一步增加反应持续时间时,缩酮基团不进行水解并形成甲基乙二醛缩醛。开发了一种制备甲基乙二醛缩酮的方法。
