2-alkyl anthraquinone is of great industrial value, not only as a chemical intermediate for the synthesis of dark high-quality dyes but also as an efficient pulping additive in the papermaking process. It is also widely used in medicine and pesticides, etc. Among the 2-alkyl anthraquinone, 2-methyl anthraquinone and 2-ethyl anthraquinone are the most common, and 2-alkyl anthraquinone can be modified according to different needs to synthesize the target compound.
In terms of dyes, 2-methylanthraquinone is chlorinated or nitrated first, and then a wide variety of anthraquinone dyes can be synthesized. Statistics show that there are as many as hundreds of anthraquinone dyes.
In the papermaking process, 2-methylanthraquinone is a very efficient additive that can penetrate into the interior of the wood chip and be reduced to 2-methylanthrahydroquinone, which is unstable and easily oxidized, where the redox cycle in the process, the components in the wood chips are oxidized, which aggravates the reaction and improves the efficiency of pulping.
In medicine, alkylanthraquinones also have very significant medicinal value. According to continuous research at this stage, the antibacterial, anti-inflammatory, antiviral, and tumor-killing effects of anthraquinone compounds have been continuously explored, and some of them have been applied to actual disease-fighting work.

Product Name: Ag Nanoparticles Aqueous Dispersion
Product Ag Nanoparticles Aqueous Dispersion CAS No. 7440-22-4 Appearance Gray Powder Purity 99.9% APS 30 nm (Can be customized) Ingredient Ag Product Code NCZ-NSC414/20 Silver Ag Dispersion Description :
There are many ways silver nanoparticles can be synthesized; one method is through monosaccharides. This includes glucose, fructose, maltose, maltodextrin, etc., but not sucrose.
Ag Nanoparticles Aqueous Dispersion is also a simple method to reduce silver ions back to silver nanoparticles as it usually involves a one-step process. There have been methods that indicated that these reducing sugars are essential to the formation of silver nanoparticles.
Many studies indicated that this method of green synthesis, specifically using Cacumen platycladi extract, enabled the reduction of silver. Additionally, the size of the nanoparticle could be controlled depending on the concentration of the extract. Ag Nanoparticles Aqueous Dispersion that the higher concentrations correlated to an increased number of nanoparticles.
Smaller nanoparticles were formed at high pH levels due to the concentration of the monosaccharides. Another method of silver nanoparticle synthesis includes the use of reducing sugars with alkali starch and silver nitrate.
The reducing sugars have free aldehyde and ketone groups, which enable them to be oxidized into gluconate. The monosaccharide must have a free ketone group because to act as a reducing agent it first undergoes tautomerization. Besides, if the aldehydes are bound, it will be stuck in cyclic form and cannot act as a reducing agent.
For example, glucose has an aldehyde functional group that can reduce silver cations to silver atoms and is then oxidized to gluconic acid. The reaction for the sugars to be oxidized occurs in aqueous solutions.
The capping agent is also not present when heated.The growth of nanoseeds involves placing the seeds into a growth solution. The growth solution requires a low concentration of a metal precursor, ligands that will readily exchange with preexisting seed ligands, and a weak or very low concentration of reducing agent. The reducing agent must not be strong enough to reduce metal precursors in the growth solution in the absence of seeds.
Otherwise, the growth solution will form new nucleation sites instead of growing on preexisting ones (seeds). Growth is the result of the competition between surface energy (which increases unfavorably with growth) and bulk energy (which decreases favorably with growth).
The balance between the energetics of growth and dissolution is the reason for uniform growth only on preexisting seeds (and no new nucleation). Growth occurs by the addition of metal atoms from the growth solution to the seeds, and ligand exchange between the growth ligands (which have a higher binding affinity) and the seed ligands.
The range and direction of growth can be controlled by nano speed, the concentration of metal precursor, ligand, and reaction conditions (heat, pressure, etc.). Controlling stoichiometric conditions of growth solution controls the ultimate size of the particle. For example, a low concentration of metal seeds to metal precursors in the growth solution will produce larger particles.
Capping agent has been shown to control the direction of growth and thereby shape. Ligands can have varying affinities for binding across a particle. Differential binding within a particle can result in dissimilar growth across particles. This produces anisotropic particles with nonspherical shapes including prisms, cubes, and rods.

Ag-Doped Antibacterial Nanopowder Dispersion
Product Ag-Doped Antibacterial Nanopowder Dispersion CAS No. 7440-22-4 Appearance Gary Purity 99.9% APS 30 nm(Can be customized) Ingredient Ag Product Code NCZ-NSC430/20 Ag-Doped Antibacterial Nanopowder Dispersion Description :
Ag-Doped Antibacterial Nanopowder Dispersion is nanoparticles of silver of between 1 nm and 100 nm in size. While frequently described as being ‘silver’ some are composed of a large percentage of silver oxide due to their large ratio of surface to bulk silver atoms.
Numerous shapes of Ag-doped Antibacterial Nanopowder Dispersion can be constructed depending on the application at hand. Commonly used silver nanoparticles are spherical, but diamond, octagonal, and thin sheets are also common.
Their extremely large surface area permits the coordination of a vast number of ligands. The properties of silver nanoparticles applicable to human treatments are under investigation in laboratory and animal studies, assessing potential efficacy, toxicity, and costs.
The most common methods for nanoparticle synthesis fall under the category of wet chemistry or the nucleation of particles within a solution.
This nucleation occurs when a silver ion complex, usually Ag-Doped Antibacterial Nanopowder Dispersion, is reduced to colloidal silver in the presence of a reducing agent. When the concentration increases enough, dissolved metallic silver ions bind together to form a stable surface.
The surface is energetically unfavorable when the cluster is small because the energy gained by decreasing the concentration of dissolved particles is not as high as the energy lost from creating a new surface.
When the cluster reaches a certain size, known as the critical radius, it becomes energetically favorable, and thus stable enough to continue to grow.
This nucleus then remains in the system and grows as more silver atoms diffuse through the solution and attach it to the surface.
When the dissolved concentration of atomic silver decreases enough, it is no longer possible for enough atoms to bind together to form a stable nucleus.
At this nucleation threshold, new nanoparticles stop being formed, and the remaining dissolved silver is absorbed by diffusion into the growing nanoparticles in the solution.
As the particles grow, other molecules in the solution diffuse and attach to the surface. This process stabilizes the surface energy of the particle and blocks new silver ions from reaching the surface.
The attachment of these capping/stabilizing agents slows and eventually stops the growth of the particle.
The most common capping ligands are trisodium citrate and polyvinylpyrrolidone (PVP), but many others are also used in varying conditions to synthesize particles with particular sizes, shapes, and surface properties.
There are many different wet synthesis methods, including the use of reducing sugars, nitrate reduction, reduction via sodium borohydride.
The silver mirror reaction, the polyol process, seed-mediated growth, and light-mediated growth. Each of these methods, or a combination of methods, will offer differing degrees of control over the size distribution as well as distributions of geometric arrangements of the nanoparticle.
