SWIM recently purchased a gallon of Dichloromethane(CH2Cl2)(Stabilized)(HPLC/GC) and has been having trouble w/ his MM pBenzo Wacker....Everything is the same chemically as the last 30 successful wackers except for the DCM...Could the DCM be the problem??
You are only using the DCM for extractions, right? In that case, it is NOT the DCM.
