- Preparation of Phthalocyanine Green G Microcapsule
- Release date: November 07, 2019 Hits: 11 Category: News
Take a certain amount of phthalocyanine green G and dissolve it in toluene, add distilled water, and use styrene-maleic acid as a dispersing emulsifier. In the emulsifier, homogenize at a speed of 10000r / min-12000r / min for 10-20 O / W emulsion was formed in a minute; the pulse-formaldehyde prepolymer was mixed with the emulsion, and the catalyst was added in batches to reduce the pH of the medium. It was observed with a microscope that the polymer began to deposit on the surface of the capsule core. After that, heat to 70 ° C, continue to cover and gradually solidify. Keep the temperature for 1 hour when the pH value drops to 2-1.5, adjust the pH value with sodium hydroxide = 7, centrifuge and dry after cooling to obtain a free-flowing spherical solid. Microcapsules.
Use a microscope to monitor the entire process of microencapsulation; use scanning electron microscopy (SEM) to observe the surface morphology, particle size, and distribution of microcapsule products; use a particle size distribution analyzer to determine the average particle size of microcapsules; Buried rate.
