⚗️ Chemical & Physical Properties
3-Chlorophenoxyacetic acid appears as a white to pale yellow crystalline solid with no distinct odor. Its colorless and odorless nature distinguishes it from common food items that may have more vibrant colors and aromas.
With a molar mass of 200.62 g/mol and a density of 1.41 g/cm^3, 3-Chlorophenoxyacetic acid is significantly heavier compared to common food items such as water (18.02 g/mol, 1.00 g/cm^3) and sucrose (342.30 g/mol, 1.59 g/cm^3), making it denser and more massive.
3-Chlorophenoxyacetic acid has a melting point of 154-157°C and a boiling point of 210°C at atmospheric pressure. These values are higher than those of most common food items like butter (melting point: 32-35°C, boiling point: 150°C) and sugar (melting point: 160-186°C), indicating its greater stability at high temperatures.
3-Chlorophenoxyacetic acid is moderately soluble in water and exhibits low viscosity. This contrasts with common food items like salt (very soluble) and honey (high viscosity), highlighting its distinct solubility and viscosity characteristics compared to typical edibles.
🏭 Production & Procurement
3-Chlorophenoxyacetic acid is typically produced through the reaction of 3-chlorophenol with chloroacetic acid in the presence of a base catalyst. This results in the formation of 3-Chlorophenoxyacetic acid, which can then be further purified through techniques such as crystallization or distillation to obtain a high-quality product.
In terms of procurement and transportation, 3-Chlorophenoxyacetic acid is commonly available for purchase from chemical suppliers or manufacturers. It is often transported in liquid form in drums or containers that are specially designed to prevent leaks or spills. Due to its chemical nature, proper precautions must be taken during handling and transportation to ensure safety and prevent contamination.
When procuring 3-Chlorophenoxyacetic acid, it is essential to ensure that suppliers comply with regulations and safety standards for handling hazardous chemicals. This includes proper labeling, documentation, and storage of the product to prevent any accidents or mishaps during transport. Careful consideration should be given to the quantities required and the appropriate measures needed to handle and store the chemical safely upon receipt.
⚠️ Safety Considerations
Safety considerations for 3-Chlorophenoxyacetic acid include its potential as a skin irritant, eye irritant, and respiratory irritant. It is advisable to wear appropriate personal protective equipment such as gloves, goggles, and a respirator when handling this chemical. Additionally, it should be stored in a cool, dry, well-ventilated area away from incompatible materials such as strong oxidizers.
Hazard statements for 3-Chlorophenoxyacetic acid typically include “Causes skin irritation,” “Causes serious eye irritation,” and “May cause respiratory irritation.” These statements indicate the potential dangers associated with exposure to this chemical and underscore the importance of taking necessary precautions to avoid contact with skin, eyes, and lungs.
Precautionary statements for 3-Chlorophenoxyacetic acid may include “Wear protective gloves/protective clothing/eye protection/face protection,” “Avoid breathing dust/fume/gas/mist/vapors/spray,” and “Wash thoroughly after handling.” These statements emphasize the importance of using proper protective equipment, avoiding inhalation of the chemical, and practicing good hygiene to minimize the risk of exposure and adverse effects.
🔬 Potential Research Directions
One potential research direction for 3-Chlorophenoxyacetic acid is its agricultural applications, particularly as an herbicide or plant growth regulator. Studies may focus on its effectiveness in controlling weeds or promoting crop growth while minimizing environmental impact.
Another area of interest could be the environmental fate and toxicology of 3-Chlorophenoxyacetic acid. Research may investigate its persistence in soil and water systems, as well as its potential impact on non-target organisms. Understanding its behavior in the environment is crucial for assessing potential risks to ecosystems.
Furthermore, research could explore the biochemical mechanisms of action of 3-Chlorophenoxyacetic acid in plants or other organisms. This may involve studying its interaction with cellular processes or its effects on gene expression. Insights into its mode of action could inform the development of more targeted and efficient herbicides or growth regulators.
