Abstract
SEVERAL organic acids1–4 have been used for the quantitative precipitation of thorium. By a careful control of the pH value, thorium may be separated from the rare earths. The precipitate in most cases is rather of indefinite composition, and for a quantitative determination, it has to be ignited to thorium oxide and weighed. We have been engaged in investigating derivatives of cinnamic acid to see if they possess any advantages over other acids which have been employed hitherto.
