6、.1 Filter paper, coarse 3.2 Ethyl ether, ACS 3.3 Trichloroethylene, ACS 4.0 PROCEDURE 4.1 Place approximately 10 grams of samples, weighed to the nearest 0.01 gram, into a 500 milliliter Erlenmeyer flask. 4.2 Add 40 milliliters of trichloroethylene and place the flask on the steam bath for 30 minute
7、s. 4.3 Remove from the steam bath and cool to room temperature. 4.4 Filter the contents through a coarse filter paper collecting the filtrate in the 250 milliliter beaker which has been previously weighed to the nearest 0.1 milligram. 4.5 Wash the flash three times with 10 milliliter portions of tri
8、chloroethylene, passing the washings through the filter into the tared beaker. 4.6 Wash the oil from the filter paper using trichloroethylene, collecting the washing in the tared beaker. 4.7 Place the beaker on a steam bath and evaporate the trichloroethylene.
