example 1
[0019] Weigh the empty weight of the sample extraction cell ( M 0 is 107.3523g), take the sample in the sample extraction cell, weigh the mass M 1 It is 112.1583g, and the extraction cell is installed in the sample tray of the accelerated solvent extraction instrument; the sample is subjected to accelerated solvent extraction with a mixed solution of ethanol, benzene and ether (the ratio is 3:8:1), extraction conditions: furnace temperature 60°C, system pressure 1800psi, heating time 6min, extraction time 15min, cycle the extraction times 3 times according to this condition, then wash 3 times with acetone solution (3ml each time), nitrogen purging time 60s, remove the extraction pool and put it in an oven at 110℃, Dry to constant weight ( M 2 for 110.8106). The calculated degreasing residual rate is 72.0%, which is consistent with the standard method YC / T 347-2010 measurement result of 72.8%; and the whole extraction process takes about 1.5h, which is more time-saving tha...
