To quickly assess the difficulty of the text, read a short excerpt:
Knowing the weight of the dish empty and the dish and ester, we can get the weight of the esters formed* The porcelain dishes including the tar are al-> ways kept in the vacuum dessicator* When the method was first tried, there were two alternatives: Digitized by Google Digitized by Google 13 Pirst*— Bring the reaction mixture into the ex- traction funnel, etc*, as above described • Second ♦—Evaporate the solvent in a porcelain dish, thus eliminating the possibility of a loss in esters by the s...olubility of the solvent in the alkaline water solution. IThe residue was then taken up by CHCl- and brought into the extraction funnel. This also would elim- inate the greater part of the Hglg formed* Bxperiment About 0*5 gm« of Eg salt ^ B c.o. CH^I -t- 5 c«c« ether were heated at 100^ for two to three hours and ex- tracted by the first method. The weight of the esters was 0.109 grams. Another tube run along with this one and extracted by the second method gave as the weight of esters 0.0406 grams.
