Product Name: Factory Supply liquid sodium ethoxide cas 141-52-6 With Best Price
CAS Number: 141 - 52 - 6
Appearance: It is a liquid under normal conditions. Its color and clarity can vary depending on the purity and manufacturing process. Generally, high - purity liquid sodium ethoxide appears as a clear, colorless to slightly yellowish liquid.
Chemical Formula: C₂H₅ONa
Molecular Weight: 68.05 g/mol
Boiling Point: Approximately 91°C at 1 atm
Flash Point: Around 28°C
Solubility: It is highly soluble in ethanol and other polar solvents, which makes it a versatile reagent in various chemical reactions.
1. Chemical Synthesis: Liquid sodium ethoxide is a crucial base in many organic synthesis reactions. It can be used in the Claisen condensation reaction, where it promotes the formation of carbon - carbon bonds between esters. This reaction is widely used in the production of pharmaceuticals, fragrances, and agrochemicals.
2. Fuel Additives: It can be used as an additive in biofuels. By reacting with certain components in biofuels, it can improve the fuel's combustion performance and stability, reducing emissions and enhancing engine efficiency.
3. Detergent Production: In the manufacturing of detergents, liquid sodium ethoxide can be used in the saponification process. It reacts with fatty acids to form soap and glycerol, which are the main components of many detergents.
1. Storage: Store liquid sodium ethoxide in a cool, dry, and well - ventilated area. Keep it away from sources of heat, open flames, and moisture. It should be stored in a tightly sealed container made of a compatible material, such as a glass or a special plastic container resistant to its corrosive nature.
2. Handling: When handling liquid sodium ethoxide, wear appropriate personal protective equipment (PPE), including safety goggles, gloves, and a lab coat. Avoid contact with skin, eyes, and clothing. In case of contact, immediately flush the affected area with a large amount of water and seek medical attention.
3. Reaction Conditions: In chemical reactions, carefully control the reaction temperature, pressure, and the ratio of reactants. Add liquid sodium ethoxide slowly to the reaction mixture to avoid violent reactions, especially when it is used in highly exothermic reactions.
Caso 1: Síntesis farmacéutica
A pharmaceutical company was synthesizing a new anti - inflammatory drug. They used liquid sodium ethoxide in the Claisen condensation step. The reaction was carried out in a three - necked flask under an inert nitrogen atmosphere. By precisely controlling the reaction temperature at 60°C and adding liquid sodium ethoxide drop - wise over a period of 30 minutes, they were able to obtain a high - yield (over 80%) of the desired intermediate product. This intermediate was then further processed to form the final anti - inflammatory drug, which passed the preliminary clinical trials.
Case 2: Biofuel Improvement
A biofuel producer added a small amount (about 1%) of liquid sodium ethoxide to their biodiesel product. After thorough mixing, they conducted engine tests. The results showed that the modified biodiesel had a 10% reduction in particulate matter emissions and a 5% increase in fuel efficiency. This improvement not only met the environmental regulations but also enhanced the market competitiveness of their biofuel.
