Dibenzyl oxalate with the CAS number 7579 - 36 - 4 is a chemical compound that is widely used in various industries. Its molecular formula is C16H14O4, and it has a molecular weight of approximately 270.28 g/mol. The appearance of dibenzyl oxalate is typically a white crystalline powder. It has a relatively low solubility in water but is soluble in organic solvents such as ethanol and acetone. The melting point of this compound is around 71 - 73°C. These physical and chemical properties make it suitable for a variety of applications.
Dibenzyl oxalate has multiple uses in different fields. In the chemical industry, it serves as an important intermediate in the synthesis of other organic compounds. It can be used in the preparation of esters and amides through chemical reactions. In the fragrance and flavor industry, dibenzyl oxalate can contribute to the creation of unique scents and flavors due to its aromatic properties. It can also be used in the research and development of new materials, such as in the production of certain polymers where it can act as a cross - linking agent or a modifier to improve the material's properties.
When using dibenzyl oxalate, proper safety precautions should be taken. It is recommended to wear appropriate personal protective equipment, including gloves and safety glasses. In a laboratory or industrial setting, dibenzyl oxalate should be stored in a cool, dry place away from direct sunlight and sources of heat. When handling the compound, it should be done in a well - ventilated area to avoid inhalation of dust. For chemical reactions, the appropriate reaction conditions such as temperature, pressure, and reaction time should be carefully controlled according to the specific reaction requirements. Usually, it is added to the reaction system in a measured amount, and the reaction mixture should be stirred evenly during the reaction process.
Case 1: Synthesis of a New Ester
In a chemical research laboratory, a team of chemists aimed to synthesize a novel ester compound. They used dibenzyl oxalate as a key starting material. First, they dissolved dibenzyl oxalate in anhydrous ethanol in a round - bottom flask under a nitrogen atmosphere. Then, they added a specific alcohol and a catalytic amount of an acid catalyst. The reaction mixture was refluxed at a controlled temperature for several hours. After the reaction, the product was purified through a series of steps including extraction, washing, and distillation. The resulting ester had excellent properties and was potentially useful in the production of high - performance coatings.
Caso 2: Creación de fragancias
A fragrance company was developing a new perfume. They incorporated dibenzyl oxalate into the fragrance formula. The compound added a subtle, sweet, and floral note to the perfume. Through a combination of various fragrance components, the perfume was well - received in the market. The unique properties of dibenzyl oxalate allowed it to blend well with other scents and create a long - lasting and appealing fragrance.
