Hi Scott; I notice my reactor drops a few degrees during the reaction too. I suspect this is due to that addition of methoxide which does warm a bit but is cooler than the reactor temperature for sure (but I have not bothered to do the heat calculations). Some reactions are endothermic

This is very interesting question as some ethanol based reaction are reported , not to need energy input ,and can go at lower temperature favourable but most of the reactor need energy , that is absorbing energy to release the products Pannirselvam P.VHi Scott;I notice my reactor drops a few

Hello Scott Hello, I was just wondering if anyone has observed a relation of reaction temperature to reaction completion. Based on (many) batches I have run (modified appleseed design) Aarghh!!! A crappleseed! LOL! I have always noted a decrease in temp after 1.5 - 2 hours of mixing
