Answer #1

Recrystallization principle involves compound should be insoluble in solvent at room temperature and soluble at high temperature.

DMSO is also called as a universal solvent as it dissolves all the organic compounds in it at room temperature. Also, if there is any compound which can be crystallized at low temperature, DMSO becomes more difficult as melting point of DMSO is 18 °C. If temperature is lowered then DMSO will precipitate.

therefore we can't use DMSO as recrystllization solvent.

Explain briefly why recrystallization can never result in 100% mass recovery even if you used pure material. Also explain why mass recovery is greater if you cool to 0 degrees C rather than room temperature. Explain very briefly why mass recovery is reduced if you use an excess amount of boiling solvent and why washing product crystals with excessive amounts of solvent especially warm solvent can result in reduced mass recovery.
