Detailed Manufacturing Process of Basic Green 4 The production of high-purity Basic Green 4 (Malachite Green, CAS 2437-29-8 ) involves a meticulously controlled multi-step synthesis process designed to yield a product with consistent color strength, solubility, and minimal impurities. Moneidechem adheres to rigorous quality protocols, ensuring that every batch meets or exceeds international standards. Key Raw Materials: Dimethylaniline: A crucial amine precursor. Benzaldehyde: Provides the central carbon backbone. Hydrochloric Acid or Sulfuric Acid: Used for pH control and catalysis. Oxidizing Agents: Typically lead dioxide or manganese dioxide, essential for color formation. Manufacturing Process Flow: Step 1: Condensation Benzaldehyde reacts with two equivalents of dimethylaniline in the presence of an acid catalyst (e.g., concentrated HCl). This forms Leucomalachite Green , a colorless precursor. Step 2: Oxidation The Leucomalachite Green is then oxidized using agents like lead dioxide or manganese dioxide. This step removes two hydrogen atoms, forming the conjugated system responsible for the vibrant green color of Basic Green 4 . Step 3: Salt Formation & Purification The oxidized product is reacted with an acid (e.g., oxalic acid, hydrochloric acid) to form the stable salt form, which is the commercial Basic Green 4 . Subsequent steps include filtration, washing, drying, and milling to achieve desired purity and particle size. Step 4: Quality Control Each batch undergoes rigorous testing for assay, solubility, moisture content, heavy metals, and color strength to ensure it meets Moneidechem's exacting specifications and industry standards like ISO 9001 and REACH regulations.
