Usage

General Description

2-Aminoethoxyethanol, also known as AEE, is a chemical compound with the formula C4H11NO2. It is a colorless, hygroscopic liquid that is soluble in water and has a faint ammonia-like odor. AEE is commonly used as a solvent and in the production of a variety of products, such as cosmetics, detergents, and paints. It is also used as a stabilizer for pesticide formulations, as well as in the manufacturing of pharmaceuticals and textile chemicals. AEE is known for its ability to dissolve various substances, making it a valuable ingredient in many industrial and commercial applications. However, it is important to handle AEE with care, as it can cause skin and eye irritation, and prolonged or repeated exposure can lead to respiratory issues.

Supramolecular compound nano-carrier as well as preparation method and application thereof

The invention discloses a supramolecular compound nano-carrier as well as a preparation method and application thereof, and relates to the technical field of polymer chemistry and biological detection engineering. According to the supramolecular compound nano-carrier disclosed by the invention, a two-dimensional nanosheet supramolecular structure system generated by self-assembly is driven by an anion induction effect, and a supramolecular compound nano-carrier is of a single-layer nanosheet supramolecular structure constructed by a highly-oriented one-dimensional nanorod. A hydrophobic perylene group part is used as a skeleton part for constructing the highly-oriented one-dimensional nanorod, and the charge density of a single-layer nanosheet can be regulated and controlled. The surface of the water-soluble multivalent hydrophilic part can be loaded with DNAzyme deoxyribozyme for specific detection of heavy metal ions through electrostatic interaction, and the water-soluble multivalent supramolecular compound nano sensor is constructed. Based on a fluorescence change mechanism caused by specific cutting of heavy metal ions, The fluorescence detection of the heavy metal ions in food and biological tissues is realized, and the detection effect of the heavy metal ions is greatly enhanced.

METHOD FOR PRODUCING ALKANOL AMINES BY HOMOGENEOUSLY CATALYZED ALCOHOL AMINATION

PROBLEM TO BE SOLVED: To provide a method for producing alkanol amines by alcohol amination of diols using ammonia under elimination of water. SOLUTION: The invention relates to a method for producing alkanol amines which comprise a primary amino group (-NH2) and a hydroxyl group (-OH), by alcohol amination of diols comprising two hydroxyl groups (-OH) using ammonia under elimination of water. The reaction is homogeneously catalyzed in the presence of at least one complex catalyst which contains at least one element selected from groups 8, 9 and 10 of the periodic table and at least one donor ligand.
