1-Propanone, 1-(4,4-dimethyl-2-thioxo-3-oxazolidinyl)- - Introduction
4,4-Dimethyl-3-acetamide oxazolidin-2-sulfur, also known as DEET, is a commonly used mosquito repellent.
Its properties include the following:
1. Appearance: DEET is a colorless liquid that can be evaporated at room temperature;
2. Solubility: DEET can be dissolved in many organic solvents, such as alcohols, ketones and ethers, and can also be dissolved in some non-polar solvents;
3. Stability: DEET can be stored for a long time under stable conditions.
The use of DEET mainly focuses on the following two aspects:
1. mosquito repellent: DEET has a good repellent effect, often used to make anti-mosquito liquid, anti-mosquito spray and other products;
2. Solvent: Because DEET can be dissolved in a variety of organic solvents, it is often used as a solvent, for example, it can be used in industry to synthesize rubber.
DEET preparation method generally through the following steps:
1. with methyl isocyanate as raw material, and Mr. ethanol into formylglycine ethyl ester;
2. The formylglycine ethyl ester is reacted with thiocyanate to obtain 4,4-dimethyl-3-acetamide oxazolidin-2-sulfur.
Regarding safety information, DEET has a certain degree of toxicity, so you need to pay attention to the following matters when using it:
1. Avoid contact with eyes, mouth and damaged skin;
2. long-term or excessive contact may cause irritation and damage to the skin and eyes;
3. Try to avoid direct inhalation to avoid adverse effects on the respiratory tract;
4. Avoid contact with fire and high temperature materials to avoid fire or explosion.
