Overview

Excerpt from University of Kansas Science Bulletin, Vol. 28 The preparation of thallous formate from the metal can be carried out in a number of ways. A simple method consists of first con verting it into thallous hydroxide. This can be done by placing shavings of the metal in an evaporating dish and adding enough water to almost cover the metal. If part of the metal is left exposed to the air the metal is gradually converted into thallous hydroxide by the action of the oxygen of the air and of the water. The thallous hydroxide can then readily be converted into the formate by treat ing it with formic acid. The excess of formic acid can be removed by evaporation at 100 C. This method serves very well, but it re quires much patience and time to prepare the thallous hydroxide. About the Publisher Forgotten Books publishes hundreds of thousands of rare and classic books.
