There are many excellent merits:
(1) The selective absorption as the different size and shape of molecules, that is to say, it only absorbs those molecules of which the diameter is less than the pore size of molecular sieve.
(2) To those smaller polar molecules and the unsaturated molecules, it has the property of selective absorption. The bigger the[...] Details...  Allyl acetate
