Hi! After BS's wacker i washed it as read. Then i distilled it to obtain MDP2P. After the DCM the MDP2P came over, but a lot (about 150ml !) of black tar was left. After cooling it was nearly impossible to get rid of it, used a lot of aceton and sand to 'wash' it out. What has happened ? Why this much tar ? Did i ran the MM wacker too hot ? I have read that this is not good. Thanx
