Ukusetshenziswa kwe-5A Molecular Sieve, ukusebenza kokuphelelwa amanzi kwamanzi kwe-5A ye-molecular sieve kulula, futhi isisefo se-molecular singafakwa ngokuqondile ekususweni kwe-solvent, noma isisombululo negesi kungadlula ngokuqondile kumbhoshongo we-molecular sieve adsorption.Izisefo zamangqamuzana zinamandla okukhangisa futhi zingasusa amanzi kuzincibilikisi eziphilayo namagesi, kodwa azikhangisi izincibilikisi namagesi (njenge-tetrahydrofuran).Indlela yokuqala isebenzisa i-caustic soda yokuphelelwa amanzi emzimbeni, encibilika kalula emanzini, futhi akulula ukuyihlukanisa ne-tetrahydrofuran ngemva kokuphelelwa amanzi emzimbeni, futhi akulula ukuyibuyisela kabusha ngemva kokusebenzisa i-caustic soda, okwandisa izindleko.
Ukusebenzisa umhwamuko wamanzi njenge-ejenti ye-desorption ukuze uvale isihlungo se-molecular n-alkanes, isisefo se-molecular 5A singasusa ukungcola kwe-polar futhi sibuyisele umsebenzi wokusebenza we-molecular sieve ngemva kokushisa okuphansi kanye nokwelashwa kokushisa kwamanzi afudumele;phakathi nenqubo yokuvuselela, ama-cations ngaphakathi kwesakhiwo sekristalu se-molecular sieve shift , Bese evula ngemva kokwelashwa kokushisa okuphansi kokushisa ukuze kwandiswe impilo yesihlungo samangqamuzana.
Uma usebenzisa isisefo se-molecular 5A, uwoyela namanzi awuketshezi akufanele kusetshenziswe, futhi ukuthintana ngokuqondile namafutha namanzi aketshezi kufanele kugwenywe ngangokunokwenzeka.
Njengohlobo lwe-alkali metal aluminosilicate, isisefo se-molecular 5A sithandwa ngamakhasimende ekomisweni kwegesi noketshezi.Ingase futhi isetshenziselwe ukucwengwa kanye nokuhlanzwa kwegesi noketshezi, njengokukhipha i-H2.
