m-Chlorocinnamaldehyde - Introduction
3-chorocinnamaldehyde is a compound with the chemical formula C9H9ClO and the structural formula C6H5CH = CHC(O)C(C1 = CC = CC = C1)OCl. The following is a description of the nature, use, formulation and safety information of 3-chorocinnamaldehyde:
Nature:
1. Appearance: colorless to yellowish liquid.
2. Boiling Point: about 200 ° C.
3. Density: about 1.21 g/cm.
4. Solubility: soluble in organic solvents, such as alcohol and ether, insoluble in water.
Use:
1. Spices: 3-chroocinnamalhyde can be used as a spice additive, giving the product a rich and warm cinnamon fragrance, often used in essential oils, perfumes, soaps and cosmetics.
2. Chemical synthesis intermediates: 3-chroocinnamaldehyde is used in drug synthesis and is often used as a starting material for synthetic compounds.
Preparation Method:
The preparation of 3-chorocinnamaldehyde generally goes through the following steps:
1. Cinnamaldehyde reacts with chlorosulfonic acid to obtain the corresponding sulfonate.
2. The sulfonation reaction is carried out to obtain the hydroxylated product of the sulfonate ester.
3. Finally, through nucleophilic substitution reaction, the hydroxyl group is replaced by chloro to generate 3-chlorocinnamalhyde.
Safety Information:
1. 3-chorocinnamalhyde is irritating and may cause irritation to the eyes, skin and respiratory tract, so protection should be paid attention to when using.
2. Avoid inhaling its vapor during operation and maintain good ventilation conditions.
3. After contact with skin, wash with detergent and water immediately.
4. Avoid reacting with strong oxidants to avoid dangerous substances.
5. Storage should be away from fire and high temperature, keep the container closed to prevent volatilization and overflow.
