Abstract: A procedure is presented for the determination of dimethylamine in crude liquors containing, in addition to dimethylamine, monomethylamine, trimethylamine and trimethylamine oxide. The sample is treated with nitrous acid which destroys most of the monomethylamine, converts dimethylamine to dimethylnitrosamine, and leaves trimethylamine and trimethylamine oxide substantially unaffected. The establishment of the alkalinity at treating has been difficult according to F.L. ENGLISH but in our experiment, that alkalinity is got simply comparatively. The dimethylnitrosamine is determined polarographically. We can recognized the following fact, by the above mentioned method, that is, long-dried sardine sample contains dimethylamine, and on the contrary fresh does not.
