A novel continuous static reactor concept improves mass transfer in two- phase chem. reactions between 1- 2 orders of magnitude. The current paradigm for chemical reactions between two liquids. requires energy- intensive mixing to disperse droplets of one phase in the continuous phase. The new reactor contacts a continuous free phase with a continuous phase constrained to a multitude of fibers. Phases come out of the reactor cleanly separated. An etherification reaction, a dehydrochlorination reaction, a transesterification reaction, and a vegetable oil neutralization were evaluated in fiber reactors.

The synthesis of soybean oil phosphate ester polyol (SOPEP) from epoxidized soybean oil (ESBO) reaction with phosphoric acid and water was investigated. The variables investigated were oxirane content of the ESBO, phosphoric acid and water stoichiometry, temp. of the reaction, rate of addn. of phosphoric acid and water, and solvent used. Changes in these variables on product parameters such as hydroxyl no., acid no., and viscosity contribute to improved adhesion, corrosion resistance, and provide water dispersibility if desired.

Static, Non-Dispersive FiberReactor™ (FR) Technology with Broad Applications for Two-Phase Chemical Reactions and Extractions.
The FR is a reactor/extractor/separator for 2 phase chemical reactions that is non-dispersive and static with 60X greater mass transfer area that gives instantaneous phase separation.
