Abstract

The invention discloses a catalyst for preparing hydroxyl-terminated aldehyde through hydroformylation of epoxyalkane, and a preparation method and application thereof. According to the preparation method, a cobalt precursor reacts with synthetic gas under the action of a sulfur-containing auxiliary agent so as to obtain a crude catalyst product. The catalyst provided by the invention is applied to preparation of hydroxyl-terminated aldehyde through hydroformylation of epoxyalkane and can inhibit yield reduction caused by hydrogenation of aldehyde, so heavy components by-produced in aldol condensation are reduced, and selectivity of 3-hydroxypropionaldehyde.

Description

technical field

[0001] The invention relates to a catalyst and its preparation method and application, in particular to a catalyst for preparing hydroxyl-terminated aldehyde by hydroformylation of alkylene oxide, its preparation method and application. Background technique

[0002] 3-Hydroxypropanal is an effective antibacterial agent, which can be used in food preservation and auxiliary treatment in the medical field. As a chemical intermediate, 3-hydroxypropionaldehyde can be further oxidized to produce monomers such as acrylic acid and acrylate, and it can also be polymerized to produce some polymer derivatives and resins. The most interesting application of 3-hydroxypropionaldehyde is further hydrogenation to generate 1,3-propanediol, which can be used to synthesize polyester materials with excellent properties—polytrimethylene terephthalate (PTT).

[0003] At present, the synthesis of 3-hydroxypropionaldehyde mainly consists of the following methods: ethylene oxide hyd...
