Specific uses include: Preparation of cotton candy essence. Preparation of kiwi essence. The deployment of melon essence. In addition, it is also used in the field of scientific research and has the characteristics of milk aroma and strawberry like aroma ============================================================================== The synthesis of maltol isobutyrate ester usually involves esterification reaction, using maltol and isobutyric anhydride as raw materials, and reacting in the presence of a catalyst. The specific process is as follows: Reaction system construction: In a three necked flask equipped with a stirrer, a dropping funnel, and an internal thermometer, toluene is added as the solvent, maltol, and sodium carbonate as the alkaline catalyst. Dropwise addition and reaction: Slowly add isobutyric anhydride at room temperature, and the dripping process lasts for about 1 hour. After the dropwise addition is complete, continue stirring the reaction for about 2 hours to allow the reaction to proceed fully. Post treatment: After the reaction is complete, stop stirring and wash the reaction solution with 15% sodium hydroxide solution to remove unreacted acid and catalyst, then wash with water. Separation and purification: The toluene solvent is recovered, and then the target product, maltol isobutyrate, can be obtained by vacuum distillation. This synthesis method is a commonly used route in laboratory and industrial production, characterized by easy availability of raw materials and relatively mild reaction conditions. Uses : used as food essence and spice, and used to prepare food essence Synonyms : no data Molecular Structure :
