534-07-6 - Introduction
1,3-Dichloroacetone is an organic compound with the chemical formula (CH3CO)2CHCl. The following is a description of the properties, uses, formulation and safety information of 1,3-Dichloroacetone:
Nature:
1,3-Dichloroacetone is a colorless liquid with a pungent odor. It has higher density, lower boiling point, soluble in water, alcohols and ether solvents. It is a flammable liquid and can react violently with strong oxidants.
Use:
1,3-Dichloroacetone is widely used in organic synthesis. It can be used as an intermediate in the preparation of organic compounds for the synthesis of chemicals such as drugs, dyes and pesticides. In addition, it can also be used as a solvent for industrial applications such as rubber processing and metal surface treatment.
Preparation Method:
The preparation of 1,3-Dichloroacetone is usually obtained by reacting butyraldehyde with hydrogen chloride under acidic conditions. In this reaction, butyraldehyde first undergoes an addition reaction with hydrogen chloride to form 1,1-dichloropropanol, and then undergoes a dehydration reaction to form 1,3-Dichloroacetone.
Safety Information:
1,3-Dichloroacetone is an organic compound, and it is necessary to pay attention to safety during use. It is an irritant substance that may cause irritation and damage when in contact with the skin, eyes, or respiratory system. It is also a flammable liquid that needs to be stored and handled to avoid contact with strong oxidants and ignition sources. Use should wear appropriate protective equipment to ensure that the operation is carried out in a well-ventilated place. In case of contact or inhalation, emergency treatment should be carried out immediately and medical help should be sought.
