摘要：The present disclosure relates, according to some embodiments, to

compositions, apparatus, methods, and systems that may be used to produce polyols, forexample, polyether polyols with a narrow range of molecular weights, with little if anyunsaturated byproducts, in a sustained and/or continuous reaction, with efficient heattransfer, and/or at high production rates. For example, in some embodiments, teachingsof the disclosure may be used to produce polyether polyols in a continuous loop flowprocess. A continuous loop flow process may be practiced such that heat is effectivelytransferred and/or product properties (e.g., range of molecular weights) arecontrollable. For example, a continuous loop flow process may use one or morecontinuous flow loops comprising a heat exchanger, a means to move material aroundeach loop, inlets for catalyst, monomer, initiator or starter, and an outlet for polyolproduct.
