Characteristics and Classifications of a Surfactant Surfactant refers to a substance that can significantly change the interface state of the solution system by adding a small amount. It has fixed hydrophilic and lipophilic groups, which can be aligned...
What Are the Ways to Distinguish Fatty Amine from Aromatic Amines? Amines are widely used, and the earliest development of the dye industry is based on aniline. Some amines are necessary for life-sustaining activities, but some are very harmful to health. Many amine ...
Application Fields of Poly Vinyl Pyrrolidone Ⅰ. Application of poly vinyl pyrrolidone in medicine and healthPoly vinyl pyrrolidone has excellent physiological inertia, does not participate in human metabolism, and has excellent biocompatibility...
Application of Fatty Amine Surfactants Fatty amine refers to a large group of organic amine compounds with carbon chain length in the range of C8-C22. Like general amines, it is divided into four categories: primary amine, secondary amine,...
Methods for Preparing Poly Vinyl Pyrrolidone Poly vinyl pyrrolidone is divided into four levels according to its average molecular weight. It is usually expressed by K value, and different K values represent the corresponding PVP average molecul...
Synthetic Methods and Use of Isopropylamine Isopropylamine is an organic substance with a chemical formula of C3H9N. Its aqueous solution is alkaline, and its mixture with air is highly explosive. It can react with oxidants. Its vapor is heavie...
Biodegradability of Cationic Surfactants Ⅰ. Biodegradability of cationic surfactantsSince cationic surfactants have strong bactericidal properties and are easily adsorbed on suspended solids, it is difficult to distinguish whether they are ...
