Abstract
Methods, systems, and computer-readable media for providing a continuous flow synthesis process including two or more multiphase reactions for producing a diphenyl siloxane product. Reactants and supporting substances are continuously added in-line of the continuous flow path to eliminate downtime associated with batch processes and increase the overall yield of the synthesis over time.

A method of synthesis of diphenyl cyclic siloxanes within a continuous flow system, the method comprising:
- mixing a chlorosilane substance and a solvent to form a chlorosilane-solvent mixture;
- providing, into a first reactor of the continuous flow system, the chlorosilane-solvent mixture and an acid scavenger substance;
- reacting, in the first reactor of the continuous flow system, the chlorosilane-solvent mixture and an acid scavenger substance to form a first reaction product;
- providing, into a separator, the first reaction product to remove one or more waste products from the first reaction product;
- providing, into a second reactor of the continuous flow system, the first reaction product and a methanol substance;
- and
- reacting, in the second reactor of the continuous flow system, the first reaction product and the methanol substance to form a diphenyl cyclic siloxane product.
