Dear Mr. Kamal
Nice to see your point about TP handling. The excess can be removed by nitrogen flushing v easily. Thanks. Sudhir Kumar [email protected] |

Flushing with N2 takes too long. Depending on scale, you may want to quench with methanol (this makes dimethyl carbonate) which can be removed when you evaporate your solvent. Of course, methanol may react with your isocyantate too....
