Amine gas plant at a natural gas field. Amine gas treating, also known as amine scrubbing, gas sweetening and acid gas removal, refers to a group of processes that use aqueous solutions of various alkylamines (commonly referred to simply as amines) to remove hydrogen sulfide (H 2 S) and carbon dioxide (CO 2) from gases.
The addition of hydrogen and an amino group (NR 2) using reagents other than the amine HNR 2 is known as a "formal hydroamination" reaction. Although the advantages of atom economy and/or ready available of the nitrogen source are diminished as a result, the greater thermodynamic driving force, as well as ability to tune the aminating reagent ...
Amine. In chemistry, amines (/ ə ˈ m iː n, ˈ æ m iː n /, [1] [2] UK also / ˈ eɪ m iː n / [3]) are compounds and functional groups that contain a basic nitrogen atom with a lone pair.Formally, amines are derivatives of ammonia (NH 3), wherein one or more hydrogen atoms have been replaced by a substituent such as an alkyl or aryl group [4] (these may respectively be called alkylamines ...
Usually, the amine reacts as the nucleophile with another organic compound acting as the electrophile. This sense of reactivity may be reversed for some electron-deficient amines, including oxaziridines, hydroxylamines, oximes, and other N–O substrates. When the amine is used as an electrophile, the reaction is called electrophilic amination.
Polyetheramines are a group of chemicals that are aliphatic organic species based on both ether and amine groups. They are produced by reacting either ethylene oxide or propylene oxide with polyols and then aminating them.
With a potential government shutdown looming ahead of the holidays, here's what you need to know if mail services will be impacted by it.
The Leuckart reaction is the chemical reaction that converts aldehydes or ketones to amines.The reaction is an example of reductive amination. [1] The reaction, named after Rudolf Leuckart, uses either ammonium formate or formamide as the nitrogen donor and reducing agent.
Directions The day before: Slice bread into 1" cubes and leave out overnight to dry out. (Alternately, place bread on a baking sheet and bake at 200º for 20 minutes, then let cool.)
