Common organic solvents, commonly used in organic solvents, have selectively dissolved organic matter. When acetone is present in the aqueous solution, it can inhibit the dissociation of substance in solution. Colorimetric determination of cobalt and iron with sulfur. Color reaction test for barium and strontium. Micro analysis was used as a fixing agent, the tissue of the hardening and dehydration. Extraction of various components in animals and plants.

Urgent rescue: inhalation: quickly from the scene to the fresh air. Maintain airway patency. If breathing is difficult, give oxygen. If the breath stops, immediately carry out artificial respiration. Medical treatment.

Ingestion: drink plenty of warm water, vomiting, medical treatment.

Skin contact: remove contaminated clothing, wash the skin with soap and water thoroughly.

Eye contact: to lift the eyelids, with the flow of water or saline rinse. Medical treatment.

Fire extinguishing methods: fire extinguishing agent: Anti - soluble foam, dry powder, carbon dioxide, sand. Invalid water use.

Fire precautions: as far as possible the containers from fire to open. Water spray to keep the container cool until the end of the fire. If the containers in the fireground have discoloration or from security

The sound of the pressure relief device shall be immediately evacuated.
