Precipitation polymerizationContinuous processDroplet-based millifluidicsAcrylic acidSupercritical CO2In this work, the flow of immiscible fluids in microchannels is studied. Flow pattern diagrams obtained in microfluidic chips are presented. Monodisperse droplets or parallel flows are obtained depending on the...
Amines work well, and the resulting complex can be activated by amine acceptors such as isocyanates, acid chlorides or sulfonyl chlorides [79]. Aldehydes and organic acids have also been used as deblockers [80,81]. The amine has a major effect on polymerization reactivity, and so the amine...

3-hydroxy-2-methylpropionic acid over TiO2at 210 °C to methacrylic acid with high purity exceeding 90 % and a yield over 85 % [31]. The same approach was for catalytic dehydration of 3HP to AA. The effect of the substrate flow rate on the dehydration step was tested in a continuous ...
Scheme 3. Continuous flow reactor device. The residence time of the fluids in the expanded bed was regulated by changing the flow rate of the pump. As the reactive fluids flow upward, the catalyst resin floats upward and the expanded bed forms. The pressure inside the column remains below 1...
wherein the at least one polymerization reactor is at least one of a continuous reactor or a semi-batch reactor; and passing at least a portion of the polypropiolactone outlet stream to an acrylic acid production zone comprising a thermolysis reactor that receives the at least a portion of the...
An initial charge containing 58.51 g butyl acrylate, 25.21 g 2-hydroxypropyl acrylate, 9.37 g t-octyl acrylamide, 5.94 g acrylic acid, 132.0 g ethyl acetate (solvent), and 0.17 g 2,2′-azobisisobutyronitrile (AIBN) (polymerization initiator) was prepared and charged to a 2-L 4-neck round...
Acrylic acid has a very high polymerizability, and a solid substance is frequently formed by a polymerization reaction in the step of distillation and purification, whereby a trouble such as clogging of devices takes place, which tends to hinder a constant continuous operation. Therefore, by addin...
Furfural and acrolein are known to act as detrimental chain terminators in acrylic acid polymerization reactions. Also, furfural and/or acrolein are known to have adverse effects on the color of purified product and/or to subsequent polymerized products. In addition to the acrylic acid and the al...
