Abstract

The invention discloses a D-(-)-3-phosphoglycerate bonded silica gel grease adsorbent, and relates to the technical field of grease adsorbents. The D-(-)-3-phosphoglycerate bonded silica gel grease adsorbent is prepared from the following steps: (1) sodium silicate and sulfuric acid are taken as raw materials, and gelling, acidifying treatment, aging, washing, chambering and drying are performed on the raw materials to obtain silica gel; (2) the silica gel and 3-bromopropanol are reacted to obtain an intermediate I; (3) the intermediate I and D-(-)-3-phosphoglyceric acid are reacted to obtainD-(-)-3-phosphoglycerate chiral molecule bonded grease silica gel; (4) the D-(-)-3-phosphoglycerate chiral molecule bonded grease silica gel is washed, and then is vacuum dried at room temperature toobtain the finished product D-(-)-3-phosphoglycerate bonded silica gel grease adsorbent; and (5) after the finished product D-(-)-3-phosphoglycerate bonded silica gel grease adsorbent passes inspection, packaging and storage are performed on the finished product. The prepared modified grease silica gel adsorbent has high selective adsorption on phospholipid and saponin in grease and the adsorptionrate reaches above 98%.

Description

technical field [0001] The invention belongs to the technical field of grease adsorbents, in particular to a D-(-)-3-phosphoglycerate-bonded silica gel grease adsorbent. Background technique [0002] Phospholipids are present in the cells of all animals and plants. Animal phospholipids are mainly derived from animal brain tissue, liver, kidney, eggs and muscle tissue. Plant phospholipids mainly exist in oil seeds, and most of them exist in the colloidal phase, and exist in a combined state with proteins, sugars, fatty acids, bacteriodols, vitamins and other substances. Mainly distributed in seeds, nuts and grains, such as corn, cottonseed, rapeseed, peanut and sunflower seeds contain a certain amount of phospholipids. Saponins exist in the plant kingdom and are composed of sapogenins, sugars, uronic acids or other organic acids, and are also widely distributed in seeds, nuts and grains. Both phospholipids and saponins are surfactants, which have strong emulsification and ...
