WebEthylamine can be used as a reagent: In the hydroamination reaction to prepare ethylamine derivatives by addition reaction with alkynes using the Ind 2 TiMe 2 catalyst.; To prepare … WebMay 16, 2024 · [OH −] = 0.006928 M pH = 11.85 Explanation: You are given some solution of ethylamine, an organic molecule, which gives off a basic solution in pure water. How do I know the solution will be basic and not acidic? Well, look at the Kb provided. The Kb is called the base dissociation constant. Ethylamine, also known as ethanamine, is an organic compound with the formula CH3CH2NH2. This colourless gas has a strong ammonia-like odor. It condenses just below room temperature to a liquid miscible with virtually all solvents. It is a nucleophilic base, as is typical for amines. Ethylamine is widely … See more Ethylamine is produced on a large scale by two processes. Most commonly ethanol and ammonia are combined in the presence of an oxide catalyst: CH3CH2OH + NH3 → CH3CH2NH2 + H2O In this reaction, … See more • Safety data at www.inchem.org • CDC - NIOSH Pocket Guide to Chemical Hazards See more Like other simple aliphatic amines, ethylamine is a weak base: the pKa of [CH3CH2NH3] has been determined to be 10.8 See more Ethylamine is a precursor to many herbicides including atrazine and simazine.
