 Characteristics and Advantages High-purity GLDA is favored because of its unique advantages: Green and environmentally friendly, derived from nature: The main raw material for the synthesis of GLDA comes from the natural amino acid - L-glutamic acid, which means that over 48% of the carbon in its products comes from renewable resources. Its most prominent advantage is its excellent biodegradability, which can be rapidly and thoroughly degraded in the natural environment, avoiding the problem of persistent residue of traditional chelating agents (such as EDTA) in the environment [ccitation:10]. Strong chelating ability: The GLDA molecule has four carboxylic acid groups and can form stable complexes with various metal ions such as calcium (Ca²⁺), magnesium (Mg²⁺), and iron (Fe²⁺/³⁺). Its chelating ability is even superior to that of traditional EDTA. More importantly, it can maintain high solubility and high activity within a wide pH range from acidic to alkaline. Safe and gentle:...

  Molecular properties and technical advantages of aniline: Outstanding performance of multi-functional platform molecules Aniline (C₆H₅NH₂, CAS 62-53-3 ), as the simplest primary aromatic amine, has a unique molecular structure that makes it an indispensable multifunctional platform molecule in the field of chemical engineering. In the aniline molecule, the amino group is directly connected to the benzene ring, forming a stable conjugated system. This structure endows it with excellent nucleophilicity and coordination ability, which is the basis for its wide application in multiple fields. The latest technological breakthroughs have significantly enhanced the performance of aniline. Through the nano-coating technology , the oxidation induction period of aniline has been significantly extended from 48 hours to 600 hours, greatly enhancing the stability of the product. The compound application with ionic liquids increases the solubility of aniline in organic substances by 5 to 8 ti...
