Alcohols. 
Methyl Alcohol. CH 3 OH. 
A quantity of acetone-free methyl alcohol (from Kahlbaum) was converted into the 
oxalate by Dittmar and Fawsitt’s process (‘Trans. Hoy. Soc. Edin./ 33, 2,510). 
After standing for two months over dry potassium carbonate, the product was coho- 
bated wdth quicklime, and allowed to remain in contact with fresh lime for a week. 
This process was repeated, and the resulting liquid was put over anhydrous copper 
sulphate for ten days; the alcohol, which was coloured bluish-green from the presence 
of a small cjuantity of dissolved CuS 04,.2 CH 3 OH (Forcrand, ‘ Compt. Rend.,’ 
102 , 551), was siphoned off and distilled. It boiled between 65°'24 and 65°'49; 
n — 25°'3 ; t = 28° (emergent column). Bar., 771'7 millims. Corrected and reduced 
b.p. = 64°-96.
