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.
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 ...
The Canadian province of Ontario set the standard at 9 ng/L. The potential problem is greater for recycled water that can contain dimethylamine. [4] Further, NDMA can form or be leached during treatment of water by anion exchange resins. [5]
1-Ethyl-3-(3-dimethylaminopropyl)carbodiimide (EDC, EDAC or EDCI) is a water-soluble carbodiimide usually handled as the hydrochloride. [1] It is typically employed in the 4.0-6.0 pH range. It is generally used as a carboxyl activating agent for the coupling of primary amines to yield amide bonds.
