Usage

Uses

Used in Textile Industry:
p-Phenylenediamine hydrochloride is used as a dyeing agent for textiles, providing coloration to fabrics. Its effectiveness in this application is due to its ability to bind with the fibers, resulting in a stable and long-lasting color.
Used in Fur Industry:
In the fur industry, p-Phenylenediamine hydrochloride is used as a dyeing agent for furs, ensuring that the fur maintains its color and appearance over time. p-phenylenediamine hydrochloride's ability to penetrate and bind with the fur fibers makes it a preferred choice for this application.
Used in Hair and Cosmetic Industry:
p-Phenylenediamine hydrochloride is used as a coloring agent in hair dyes and cosmetics, providing a wide range of color options. Its coloring properties allow for the creation of various shades and tones, making it a versatile ingredient in these products.
However, it is important to note that exposure to p-Phenylenediamine hydrochloride can potentially cause skin, eye, and respiratory tract irritation. Prolonged exposure might also have mutagenic effects. Therefore, careful handling and usage are necessary to minimize health risks associated with p-phenylenediamine hydrochloride.

Reduction of dinitrobenzenes by electron-carrying catalysts in the electrosynthesis of diaminobenzenes

The interaction of isomeric dinitrobenzenes (DNBs) with titanium(III), tin(II), and vanadium(II) chlorides, which are reducing agents used as electron carriers in the electrosynthesis of diaminobenzenes, has been studied. Rate constants of the reduction of isomeric DNBs and nitrophenylhydroxylamines by SnCl2 and TiCl3 in a 2 M water-alcohol solution (10 vol.% C2H5OH) of HCl were measured, and activation energies of the reduction of isomeric DNBs were determined. The rates of interaction of DNBs with the listed mediators increase in the series SnCl2 3 2. It is shown that the electrolysis of DNBs in the presence of an excess of these mediators makes it possible to obtain the corresponding diaminobenzenes with a yield of 60–90%.

Cobalt-Catalyzed Deoxygenative Hydroboration of Nitro Compounds and Applications to One-Pot Synthesis of Aldimines and Amides

The commercially available and bench-stable Co(acac)2 ligated with bis[(2-diphenylphosphino)phenyl] ether (dpephos) was employed for selective room temperature hydroboration of nitro compounds with HBPin (TOF up to 4615 h?1), tolerating halide, hydroxy, amino, ether, ester, lactone, amide and heteroaromatic functionalities. These reactions offered a direct access to a variety of N-borylamines RN(H)BPin, which were in situ treated with aldehydes and carboxylic acids to produce a series of aldimines and secondary carboxamides without the need for dehydrating and/or coupling reagents. Combination of these transformations in a sequential one-pot manner allowed for direct and selective synthesis of aldimines and secondary carboxamides from readily available and inexpensive nitro compounds.

Synthesis method of p-phenylenediamine hydrochloride

The invention relates to a synthesis method of p-phenylenediamine hydrochloride, which comprises the following steps: by using N, N-dimethylformamide as a solvent and tetramethyl ammonium bromide as aphase transfer catalyst, synthesizing p-phenylenediamine hydrochloride from p-phenylenediamine and hydrogen chloride under certain conditions and introducing hydrogen chloride into the N, N-dimethylformamide solution dissolved in p-phenylenediamine at a temperature of 10 DEG C and 30 DEG C. According to the method, hydrogen chloride is introduced into an N, N-dimethylformamide solution dissolvedin p-phenylenediamine at the temperature of 10 DEG C and 30 DEG C, the product yield is 99.50% or above, and the product purity is 99.90% or above.

A Modular Phosphorylated Glycoluril-Derived Molecular Tweezer for Potent Binding of Aliphatic Diamines

A molecular tweezer based on a glycoluril-derived framework bearing four phosphate groups was synthesized and shown to be capable of binding organic amines in aqueous solution. This work reports the Ka values for 30 complexes of this molecular tweezer and amine guests, determined by means of 1H NMR titrations. Both the hydrophobic cavity and the phosphate groups contribute to the binding. Bulkier molecules and molecules bearing negatively charged groups like carboxylates in amino acids bind less tightly due to a steric clash and coulombic repulsion. The narrow cavity and the strong ionic interactions of the phosphate groups with ammonium guests favor binding of aliphatic diamines. These binding properties clearly distinguish this system from structurally related molecular clips and tweezers.
