4-Fluorocinnamaldehyde - Introduction
trans-4-fluorocinnamaldehyde is an organic compound with the chemical formula C9H9FO. The following is a description of the properties, uses, preparation and safety information of trans-4-fluorocinnamaldehyde:
Nature:
trans-4-fluorocinnamaldehyde is a colorless to light yellow liquid with a special aromatic odor. It has a density of about 1.15g/cm³, a boiling point of about 267-269°C, and a flash point of about 118°C. It is stable at room temperature, but easy to decompose when exposed to heat. The solubility of trans-4-fluorocinnamaldehyde is better, and the solubility in alcohol and ether solvents is higher.
Use:
trans-4-fluorocinnamaldehyde is mainly used as a synthetic raw material in flavors and spices for flavoring and flavoring. It can also be used to synthesize other organic compounds, such as drugs, dyes and pesticides.
Preparation Method:
The preparation of trans-4-fluorocinnamaldehyde can be achieved by fluorination of cinnamaldehyde. One commonly used method is the reaction of cinnamaldehyde with hydrogen fluoride to give trans-4-fluorocinnamaldehyde. The specific reaction conditions and the choice of catalyst will affect the efficiency and yield of the reaction.
Safety Information:
trans-4-fluorocinnamaldehyde is relatively stable under general conditions, but it is still necessary to pay attention to safe operation. Contact with skin and eyes may cause irritation and eye damage, so wear appropriate personal protective equipment when using. Avoid inhalation of its vapor, if inhalation occurs, should immediately move to fresh air. Care should be taken to avoid contact with fire and exposure to high temperatures during storage and handling.
