| titleOfInvention | Sodium bicarbonate-coated microsphere and preparation method thereof |
| abstract | The invention provides a sodium bicarbonate-coated microsphere which mainly comprises sodium bicarbonate and ethyl cellulose, and the mass percentages of the components are as follows: 1.42 to 2.93 percent of sodium bicarbonate and 97.07 to 98.58 percent of ethyl cellulose. Firstly, dispersing a sodium bicarbonate aqueous solution in an acetonitrile solution of ethyl cellulose to prepare an internal oil phase (S/O), then injecting the internal oil phase into soybean oil containing span 80 to form S/O/O emulsion, then volatilizing the acetonitrile, and separating out the ethyl cellulose in the internal oil phase to form microspheres. The invention adopts ethyl cellulose microspheres to encapsulate sodium bicarbonate, and utilizes the microspheres to effectively encapsulate the sodium bicarbonate to realize the slow release of the sodium bicarbonate. |
