Isticmaalka 5A Molecular Sieve, hawlgalka fuuq-bax ee 5A shaandho molecular waa mid fudud, shaandhada molecular si toos ah ayaa loo gelin karaa ka saarista dareeraha, ama xalka iyo gaasta si toos ah ayaa loo sii marin karaa munaaradda shaandhada molecular.Shaandhooyin molecular ah waxay leeyihiin awood adsorption oo door ah waxayna ka saari karaan biyaha dareerayaasha organic iyo gaaska, laakiin ha ku milmin dareerayaasha iyo gaaska (sida tetrahydrofuran).Habka asalka ah waxa uu fuuq baxa u isticmaalaa soodhaha caustic, taas oo si fudud ugu milmay biyaha, mana fududa in laga sooco tetrahydrofuran ka dib fuuqbaxa, mana fududa in dib loo warshadeeyo ka dib marka la isticmaalo soodhaha, taas oo kordhisa qiimaha.
Isticmaalka uumiga biyaha sida wakiilka wasakhaysan si loo demiyo shaandhada molecular n-alkanes, shaandhada molecular ee 5A waxay ka saari kartaa qaar ka mid ah wasakhowga polar waxayna dib u soo celin kartaa hawsha shaqada ee shaandhada molecular ka dib heerkulka hoose iyo daaweynta kulaylka biyaha diiran;inta lagu guda jiro habka dib u cusboonaysiinta, cations gudahood qaab-dhismeedka crystalline ee shift shaandho molecular , Ka dibna fur ka dib daawaynta kulaylka hoose si ay u kordhiyaan nolosha shaandho molecular.
Marka la isticmaalayo 5A shaandho molecular, saliid iyo biyo dareere ah waa in aan la isticmaalin, iyo taabashada tooska ah ee saliidda iyo biyaha dareeraha ah waa in laga fogaado inta ugu badan ee suurtogalka ah.
Sida nooc ka mid ah aluminosilicate birta alkali, 5A shaandho molecular waxaa doorbiday macaamiisha qalajinta gaaska iyo dareeraha.Waxa kale oo loo isticmaali karaa sifaynta iyo nadiifinta gaaska iyo dareeraha, sida soo saarista H2.
