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.
In chemistry, ammonolysis (/am·mo·nol·y·sis/) is the process of splitting ammonia into + +. [1] Ammonolysis reactions can be conducted with organic compounds to produce amines (molecules containing a nitrogen atom with a lone pair, :N), [2] or with inorganic compounds to produce nitrides.
In chemistry, aminolysis (/am·i·nol·y·sis/) is any chemical reaction in which a molecule is lysed (split into two parts) by reacting with ammonia (NH 3) or an amine. [1] The case where the reaction involves ammonia may be more specifically referred to as ammonolysis .
Conversely, the related carbodiimide 1-Ethyl-3-(3-dimethylaminopropyl)carbodiimide (EDC) is often used for solution-phase peptide couplings as its urea byproduct can be removed by washing during aqueous work-up.

One example is Kapton where the repeat unit consists of two imide groups derived from aromatic tetracarboxylic acids. [3] Another example of polyimides is the polyglutarimide typically made from polymethylmethacrylate (PMMA) and ammonia or a primary amine by aminolysis and cyclization of the PMMA at high temperature and pressure, typically in ...
An example of a solvolysis reaction is the reaction of a triglyceride with a simple alcohol such as methanol or ethanol to give the methyl or ethyl esters of the fatty acid, as well as glycerol. This reaction is more commonly known as a transesterification reaction due to the exchange of the alcohol fragments. [2]
CH 3 COSK + RX → CH 3 COSR + KX. The analogous alkylation of an acetate salt is rarely practiced. The alkylation can be conducted using Mannich bases and the thiocarboxylic acid: CH 3 COSH + R' 2 NCH 2 OH → CH 3 COSCH 2 NR' 2 + H 2 O. Thioesters can be prepared by condensation of thiols and carboxylic acids in the presence of dehydrating ...
A diamine is an amine with exactly two amino groups.Diamines are used as monomers to prepare polyamides, polyimides, and polyureas.The term diamine refers mostly to primary diamines, as those are the most reactive.
