CHLOROACETIC ACID SODIUM SALT - Reference Information
| LogP | -3.8 at 20℃ |
| EPA chemical information | Information provided by: ofmpub.epa.gov (external link) |
| use | used in organic synthesis of pesticides, medicines, etc. used in dye synthesis, also used as herbicide used in the synthesis of dyes, pesticides and herbicides used in medicine, chemical industry, etc. sodium chloroacetate is an important fine chemical product, widely used in petrochemical, organic chemical, synthetic pharmaceutical, pesticide, dye chemical, metal processing and other industrial production organic synthesis. Medicinal. Herbicide. Dye. |
| Production method | It is obtained by the reaction of chloroacetic acid and sodium hydroxide (or sodium carbonate). Dissolve chloroacetic acid in absolute ethanol, cool to below 20°C, and slowly add sodium hydroxide saturated solution. After the reaction is completed, the crystallization is precipitated by cooling. Filtration, washing with ethanol, distillation under reduced pressure, and drying to obtain the finished product. Generally, only an aqueous solution of sodium chloroacetate is needed in organic synthesis. In this case, the aqueous chloroacetic acid solution and sodium carbonate are reacted at 70°C to make the reaction pH 6.8-7 to obtain the required sodium chloroacetate solution. |
