Minsheng brand AB-8 macroporous resin

Minsheng brand AB-8 macroporous resin Product Description I. Introduction: AB-8 is a styrene monomer in the presence of porogen to obtain a high surface area adsorbent, good ball strength, even narrow aperture distribution, is a non-polar macroporous resin. Acid, good thermal stability, the effective absorption of various small organic molecules, desorption is high. Second, product specifications: Appearance milky white opaque spherical particles weakly polar polar surface area 480-520 m2 / g average pore size of 13-15 nm pore volume of 0.73-0.77 ml / g porosity of 42-46% wet true density of 1.05-1.97 g / ml Shipping weight 0.62-0.72 g / ml water content 60-70% 3, Application: 1. Small molecule organic extraction and recovery 2. Saponins, flavonoids, terpenoids, polyphenols, isolated alkaloids extracted. 3. Extraction of natural pigments isolated. 4. Antibiotics, herbal extracts separated. Fourth, the product uses: 1. Pretreatment: from ethanol to 1BV / h speed Guozhu, to double the outflow of fluid turbulence is not muddy up the water, then washed with water until no alcohol taste. 2. Feed liquid into the column requirements: free of sediment, neutral or acidic, tannin removal. 3. Feed rate: 1 ~ 4BV / h. 4. Common desorption solution: 2% ~ 5% NaOH, ethanol, methanol, acetone. 5. Desorption flow rate: 0.5 ~ 2BV / h. Fifth, the corresponding product: HP-21 Xingtai people's livelihood Resin Technology Co., Ltd.
