Answer 1

According to the preparation of lower-sulfur content expand-able graphite with potassium permanganate as oxidant, 2.0 g of nature flake graphite (200 mesh), 1.0 g of potassium permanganate, and 8.0 g perchloric acid were placed into a dry three-necked bottle equipped with a thermometer, and a stirrer, and putted the bottle into water bath kettle. The mixture was continually stirred for 40 min at 35˚C, then was washed to neutrality with water and dried at the temperature of 60˚C to produce the dry expandable graphite. A 500 ml silica beaker containing 1 g of the sulfur-free expandable graphite was put into a microwave oven at 1000˚C for 20 s, and finally the sulfurfree expanded graphite (EG) was obtained.
