Abstract: A multistage tubular reaction system and method for preparing methylol derivatives of an aldehyde includes a tubular reaction system with a plurality of successive reactor stages comprising a plurality of jacketed reaction tubes provided with a cooling system adapted to control flow of a cooling medium through said jacketed reaction tubes. The cooling medium flow is controlled independently in different stages in response to temperature measurements in the reaction system to regulate temperature. In order to further reduce temperature spikes and byproduct generation, aldehyde is stepwise added to the production stream at a plurality of feed ports proximate to reaction tubes equipped with tube inserts to enhance mixing and heat transfer.

Abstract: A multistage tubular reaction system and method for preparing methylol derivatives of an aldehyde includes a tubular reaction system with a plurality of successive reactor stages provided with a formaldehyde containing feed stream. The system includes multiple feed ports for the staged addition of C2 or higher condensible aldehyde and/or base to the formaldehyde containing stream at a plurality of successive feed points to provide a production stream, which is progressively provided with additional reactants as the production stream advances through the successive reaction stages. Advantages include better temperature control and reduced byproduct formation.
