Comparison of activity and selectivity of weakly basic anion-exchange catalysts for the aldolization of butyraldehyde with formaldehyde

Aldols are important intermediates in the production of polyols, which are raw material for lubricants, surface coatings, and synthetic resins. The activities and selectivities of gel-type and macroporous anion-exchange resin catalysts in the aldolization of butyraldehyde with formaldehyde in an aqueous environment were investigated at 60 °C. The experiments were carried out batchwise in a stirred glass reactor, and the reaction products were analyzed with high performance liquid chromatography. Two main products were observed, 2-ethyl-3-hydroxy-2-hydroxy-methylpropanal (trimethylolpropane aldol) and 2-ethyl-propenal (ethylacrolein). The product ratio was strongly dependent on the catalyst. The selectivity with respect to trimethylolpropane aldol varied within the range 2.7-7.3 for the catalysts investigated. Systematic kinetic experiments were carried out at 50-70 °C with the gel-type resin catalyst displaying the highest aldol selectivity. A kinetic model based on molecular mechanisms was able to describe the product distribution.

SEPARATION METHOD OF DIMETHYLOLBUTANAL AND PREPARATION METHOD OF TRIMETHYLOLPROPANE

The present specification relates to a separation method of dimethylolbutanal comprising: a step (A) of making n-butylaldehyde (n-BAL) react with formaldehyde (FA) under an alkylamine catalyst, thereby obtaining a dimethylolbutanal mixed product including dimethylolbutanal (DMB) and trimethylolpropane (TMP); and a step (B) of extracting 95% or more of DMB and 80% or more of TMP from the dimethylolbutanal mixed product by using a counter flow type extraction method using an organic solvent. In the step (B), the organic solvent has a flow rate of 70 to 110 g/min, the DMB mixed product has a flow rate of 40 to 70 g/min, and a weight ratio of the organic solvent to the DMB mixed product is 1.2 to 3. According to an embodiment of the present specification, the separation method can obtain DMB, at a high efficiency, which is used as a raw material for producing TMP. TMP can be obtained at a high efficiency by using the obtained DMB as a raw material for hydrogenation.COPYRIGHT KIPO 2019
