Cov qauv ntawm lub vijtsam molecular

Cov qauv molecular sieve tau muab faib ua peb theem:

Cov qauv tseem ceeb: (silicon, aluminium tetrahedra)

 kev 11

nws cov cai hauv qab no tau pom thaum lub silicon-oxygen tetrahedra txuas nrog:

(A) Txhua tus pa atom hauv tetrahedron tau sib koom

(B) Tsuas yog ib qho oxygen atoms tuaj yeem sib koom ntawm ob lub tetrahedra uas nyob ib sab

(C) Ob qho khoom siv txhuas tsis txuas ncaj qha

Secondary qauv-ntiv nplhaib

 kev 22

Secondary qauv---multivariate nplhaib

 kev 33

Tertiary structure---- tawb

Cov chav tsev thib ob txuas ntxiv nrog rau ib leeg los ntawm kev sib txuas ntawm cov pa oxygen los ua ib qho chaw peb sab polyhedr, hu ua lub qhov los yog qhov kab noj hniav, tawb yog lub ntsiab structural unit tsim cov zeolite molecular sieve; xws li hexagonal kem tawb, cubic (v) tawb, a tawb, B tawb, yim-sided zeolite tawb, thiab lwm yam.

Cages tau npaj ntxiv los tsim cov pob txha zeolite
