Dimethylamine is a weak base and the pKa of the ammonium CH 3-NH + 2 -CH 3 is 10.73, a value above methylamine (10.64) and trimethylamine (9.79). Dimethylamine reacts with acids to form salts, such as dimethylamine hydrochloride, an odorless white solid with a melting point of 171.5 °C.
In the form of boric acid, price per boron contained. Min. 99% pure. 6: C: Carbon: 2.267: 200 (5.54 × 10 18 kg) 0.122: 0.28: 2018: EIA Coal [19] In the form of anthracite, price per carbon contained, assuming 90% carbon content. There is a wide variation of price of carbon depending on its form.
The same vinamidinium salt 1,1,5,5-tetramethyl-1,5-diazapentadienium chloride is also formed in the reaction of 3-dimethylaminoacrolein with dimethylamine hydrochloride in 70% yield. [21] The two-step reaction of dimethylamine and 70% perchloric acid with 3-dimethylaminoacrolein forms the same iminium salt (herein referred to as 1,3-bis ...
Methylamine has been produced industrially since the 1920s (originally by Commercial Solvents Corporation for dehairing of animal skins). [4] This was made possible by Kazimierz Smoleński [] and his wife Eugenia who discovered amination of alcohols, including methanol, on alumina or kaolin catalyst after WWI, filed two patent applications in 1919 [5] and published an article in 1921.
