High Molecular Weight Alkyl Amine Nitrites and Hydrohalides¹

Abstract

NOTES 2381We estimate the over-all uncertainty in our combustion value as less than 0.025%, corresponding to a limit of 370 cal. for the molal heat of combustion. In this connection it is interesting to note that the earlier values of Stohmann,6 Roth and and BriilP now appear surprisingly good, as these exceed our present result by only 0.06 0.05 and 0.03010, respectively. On the other hand, the value reported by Barker' in 1925 is 0.45% higher than our result.
