Watermelon Ketone CAS 28940-11-6

What is Watermelon ketone?

Watermelon ketone is a chemical substance, a perfume compound with special smell, and its molecular formula is C10H10O3.
Watermelon ketone powder is colorless crystalline powder with unique watermelon flavor. It is insoluble in water but soluble in common organic solvents such as ethyl acetate and dichloromethane. Watermelon ketone has the general physical and chemical properties of alkyl ketones, for example, it has certain electrophilicity and can undergo nucleophilic addition reaction under the attack of common electrophilic reagents such as format reagents.

Watermelon ketone structure contains a ketone carbonyl structure and two ether bond units, which has good chemical conversion properties. The ether bond in its structure can be broken and decomposed under strong acid conditions, and the existence of ketocarbonyl makes it undergo nucleophilic addition reaction with common format reagents to obtain the corresponding third-order alcohol derivatives. It should be noted that in order to ensure its unique physical aroma and chemical stability, the substance should be stored in a sealed low-temperature environment (2-8 degrees refrigerator).

Product Specification

What are the raw materials needed to prepare watermelon ketone?

1. Raw materials and solvents:
The main raw material for preparing watermelon ketone is watermelon peel or watermelon juice. Usually, fresh and mature watermelons are selected as raw materials, and watermelon ketone is obtained by extraction or distillation. In addition, some solvents, such as ethanol and acetone, may be needed in the preparation process to dissolve and extract the target compound.

2. Catalysts and reaction AIDS:
In the process of preparing watermelon ketone, it may be necessary to use catalysts and reaction AIDS to promote the reaction and improve the yield. Common catalysts include enzymes, acids or metal catalysts, which are used to accelerate the reaction rate and improve the selectivity. Reaction auxiliaries, such as solvent system regulator and temperature regulator, can optimize the reaction conditions and improve the yield and purity.

3. Separation and purification agent:
After the preparation of watermelon ketone, it may be necessary to carry out separation and purification operations to obtain high-purity target compounds. In this process, commonly used separation and purification agents include activated carbon, silica gel column, gel dialysis and so on. These dosage forms can separate the target compound from other impurities through adsorption, chromatography and other functions, and achieve the purpose of purification.

4. Auxiliary agents and additives:
In the process of preparing watermelon ketone, some auxiliaries and additives can also be used to improve the quality and performance of the product. For example, antioxidants can be added to delay the oxidation process of watermelon ketone, or preservatives can be added to extend the shelf life of the product. These auxiliaries and additives should be selected and used according to specific product requirements and regulatory requirements.
