If you wish use a cold bath lower than -78 deg. C, avoid using dry ice
(CO2(s)) unless your slv is dried and even moisture will come in, use liquid
nitrogen and make sure you are doing it properly. Also use a thermometer to
monitor the temperature. Fisher Scientifc (www1.fishersci.com) sells these
kind of thermometers.

Also a good ref book that is useful *Purification of Laboratory Chemicals
(4th Edition)*, By: Armarego, W.L.F.; Perrin, D.D. (c) 1996 Elsevier (

Good Luck
