Molecular Sieve

We offer molecular sieve 3a,4a,5a,13x. 3a (pore size 3 å): adsorbs nh3, h2o, (not c2h6), good for drying polar liquids. 4a (pore size 4 å): adsorbs h2o, co2, so2, h2s, c2h4, c2h6, c3h6, etoh. Will not adsorb c3h8 and higher hydrocarbons. Good for drying nonpolar liquids and gases. 5a (pore size 5 å): adsorbs normal (linear) hydrocarbons to nc4h10, alcohols to c4h9oh, mercaptans to c4h9sh. Will not adsorb isocompounds or rings greater than c4. 13x (pore size 10 å): adsorbs di-n-butylamine (not tri-n-butylamine). Useful for drying
