Pierre,
Use what you tools you have and adjust your reaction time accordingly. If the manufacturer's specs are available to you, check the rated gph of the pump at 3' of head pressure. Then multiply that volume by ~60% due to reductions caused by pumping a fluid far more viscous than water, which is what the specs will probably refer to. Divide that volume by the volume in the reactor and you've got a very crude guestimate of the number of turnovers per hour in your reactor. To judge an appropriate reaction time, pull an exact amount of fluid (200 ml would suffice) out of the reaction stream every half-hour or hour after an arbitrary initial ~1 hour reaction period. Presuming that the contents of the reactor are kept homogenous from the pump flow, the volume of the glycerol cocktail that settles out of each sample will give you a fair gauge as to when your reaction completed. The suggestion would be to continue the reaction for ~1/2 hour beyond the point where your glyc cocktail volume stabilized.
