NOVELTY - Preparation of sheet or granular phenoxycarboxylic acid raw traditional medicine involves adding organic solvent to phenoxycarboxylic acid soluble salt water solution, then adding acid to acidify the solution or adding acid into the phenoxycarboxylic acid soluble salt water solution to acidify, then adding organic solvent, then standing and layering, separating the organic solvent from the organic phase and then granulating and tableting the obtained phenoxy carboxylic acid medicine liquid to prepare granular or sheet-shaped phenoxy carboxylic acid raw medicines.    USE - For preparation of sheet or granular phenoxycarboxylic acid raw traditional medicine (claimed).    ADVANTAGE - The method reduces the use amount of the waste water, reduces dust, generates new raw material shape which is more environment friendly and safe; reduces the raw material in the salt, does not need washing process, obviously reduces the dosage of water, reduces the post waste water processing pressure which is more environment-friendly, and prepares powder that has specific surface area is much larger, good liquidity, convenient to store, is capable of effectively preventing.    DETAILED DESCRIPTION - Preparation of sheet or granular phenoxycarboxylic acid raw traditional medicine involves adding organic solvent to phenoxycarboxylic acid soluble salt water solution, then adding acid, or adding acid to acidify the solution or adding acid into the phenoxy carboxylic acid soluble salt water solution to acidify, then adding organic solvent, then standing and layering, separating the organic solvent from the organic phase, and then granulating and tableting the obtained phenoxycarboxylic acid medicine liquid to prepare granular or sheet-shaped phenoxycarboxylic acid raw medicines; or adding acid to the phenoxycarboxylic acid soluble salt water solution to acidify, then adding organic solvent, standing and layering, separating the organic phase and evaporating the organic solvent, and then granulating and tableting the obtained phenoxycarboxylic acid medicine liquid to prepare granular or sheet-shaped phenoxycarboxylic acid raw medicines.
