The substituent R next the amine methylene bridge is an electron-withdrawing group. The original 1928 publication by Thomas S. Stevens [ 2 ] concerned the reaction of 1-phenyl-2-(N,N-dimethylamino)ethanone with benzyl bromide to the ammonium salt followed by the rearrangement reaction with sodium hydroxide in water to the rearranged amine.
The amine concentration in the absorbent aqueous solution is an important parameter in the design and operation of an amine gas treating process. Depending on which one of the following four amines the unit was designed to use and what gases it was designed to remove, these are some typical amine concentrations, expressed as weight percent of ...
These properties are influenced by a 400-450 °F (204-232 °C) continuous use temperature and a glass transition of 500 °F (260 °C). Bismaleimide resin synthetic pathway and structure This thermoset polymer type is merged into composites as a prepreg matrix used in electrical printed circuit boards , and for large scale structural aircraft ...
Techron is a patented fuel additive developed by Chevron Corporation and sold in its fuel operations (including Texaco and Caltex).It contains a polyether amine-based detergent, which is purported to dissolve deposits in automotive engines and prevent them from building up.
A nitrogen bound to both a good electrofuge and a good nucleofuge is known as a nitrenoid (for its resemblance to a nitrene). [2] Nitrenes lack a full octet of electrons are thus highly electrophilic; nitrenoids exhibit analogous behavior and are often good substrates for electrophilic amination reactions.
