  摘要：

  通式的α-烷基丙烯醛是通过通式的光学活性醛与甲醛之间的曼尼希反应制得的。从这些化合物中获得了相应的酸，腈和通式的支链烷烃。对这些合成中遇到的外消旋作用进行了评估，并在此基础上计算出了新化合物的最大分子旋转力。

  A process is described that uses a silver catalyst to convert methanol into formaldehyde in the presence of less than a stoichiometric amount of oxygen. The resulting formaldehyde is reacted without isolation with propionaldehyde over a commercially available anatase titania catalyst that is shown to be catalytically active towards the formation of methacrolein from formaldehyde and propionaldehyde with conversions and selectivities close to 90%. This titania catalyst is readily available, non-toxic, and can be used with formaldehyde and a variety of other aldehyde compounds to make α,β-unsaturated aldehyde compounds. This process benefits from low raw material costs and is economically advantaged due to the elimination of catalyst separation. This process shows promising stability and selectivity during lifetime studies, particularly when performed in the presence of a hydrogen carrier gas.

  A commercially available anatase titania catalyst is shown to be catalytically active towards the formation of methacrolein from formaldehyde and propionaldehyde with conversions and selectivities close to 90%. This titania catalyst is readily available, non-toxic, and can be used with formaldehyde and a variety of other aldehyde compounds to make α,β-unsaturated aldehyde compounds. This process benefits from low raw material costs and is economically advantaged due to the elimination of catalyst separation. An additional advantage of this method involves the ability of the catalyst to be fully regenerated after a calcination step at 450° C. in air. This process shows promising stability and selectivity during lifetime studies, particularly when performed in the presence of a hydrogen carrier gas.
