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 question is the level at which it is produced. In the U.S. state of California, the allowable level is 10 nanograms/liter. [3] 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]
It is a colorless liquid that is widely available. It is prepared by the reaction of dimethylamine and formaldehyde: [1] 2 (CH 3) 2 NH + CH 2 O → [(CH 3) 2 N] 2 CH 2 + H 2 O. It is used for the dimethylaminomethylation reactions, the reaction being initiated by the addition of a strong, anhydrous acid: [2] [(CH 3) 2 N] 2 CH 2 + H + → (CH 3 ...
Dimethylethanolamine (DMAE or DMEA) is an organic compound with the formula (CH 3) 2 NCH 2 CH 2 OH.It is bifunctional, containing both a tertiary amine and primary alcohol functional groups.
Dimethylaminoethoxyethanol is manufactured by reacting dimethylamine and ethylene oxide. [2] Other methods are also available producing streams rich in the substance which then need to be further purified.
A magnitude 4.0 earthquake rattled parts of Southern California Sunday morning. ... Sunday's 3:51 a.m. earthquake was the fifth of magnitude 3 or higher detected in Ontario since early September ...
The ultimate products of its hydrolysis is titanium dioxide and dimethylamine: Ti(NMe 2) 4 + 2 H 2 O → TiO 2 + 4 HNMe 2. In a related reaction, the compound undergoes exchange with other amines, evolving dimethylamine. TMAT has been used in metalorganic chemical vapor deposition (MOCVD). [citation needed]
