| Hazard Information | Back Directory | [Description]
2, 4-Dichloro-3, 5-Xylenol (DCMX), is a white to light yellow flake. DCMX is a secure and efficient antiseptic. It’s slightly soluble in water (20oC, 0.2g/L), very soluble in organic solvents such as alcohol, ether, ketone, etc., and dissolves in solutions of alkali hydroxides. It’s frequently used in industry fields such as personal care products such as hand-cleaning detergent, soap, dandruff control shampoo, and healthy products, such as film, glue water, oiled, textile, paper making, etc. | [Chemical Properties]
light beige powder | [Uses]
Bacteriostat in soaps; mold inhibitor, preservative. | [Preparation]
2,4-Dichloro-3,5-dimethylphenol is obtained by reaction of 4-chloro-3,5-dimethylphenol with N-chloroacetamide in glacial acetic acid with concentrated HCl. | [Production Methods]
2,4-Dichloro-3,5-dimethylphenol is obtained by reaction of 4-chloro-3,5-dimethylphenol with N-chloroacetamide in glacial acetic acid with concentrated HCl. It is used as a preservative in aqueous functional fluids and as a microbicide in disinfectants, but in comparison with 4-Chloro-3,5-Dimethylphenol is of lesser importance because it has a more intense smell and is less soluble in water.
| [Solubility in organics]
2,4-Dichloro-3,5-dimethylphenol is soluble in alkali solutions, and readily soluble in organic solvents. | [Solubility in water]
It has a solubility in water of 0.2 g/L at 20 °C. | [Properties and Applications]
