Khoom npe: MOR zeolites (toluene disproportionation)
Khoom Description
MOR zeolites, tseem hu ua MFI zeolite, yog crystalline silicoaluminophosphate nrog cov qauv tshwj xeeb. Nws muaj kev sib txuas ntawm SiO4 thiab AlO4 tetrahedra los ntawm cov txuas txuas oxygen, ua ib qho kev ua haujlwm nrog ib qho - cov kab sib txuas. Cov qauv siv lead ua yog nyob rau hauv cov kab ke monoclinic thiab zoo li rab koob - zoo li tus lossis fibrous crystals, feem ntau yog xim dawb. Qhov siab tshaj plaws thiab qhov tsawg kawg nkaus pore diameters yog 0.7nm thiab 0.58nm, feem, nrog qhov nruab nrab ntawm 0.66nm. Cov channel tseem ceeb yog tsim los ntawm 12- cov nplhaib sib koom, thiab cov silicon-rau-aluminium ratio (SiO2/Al2O3 molar ratio) nyob ntawm 8 txog 20.
Hauv cov qauv siv lead ua ntawm silicalite-1, tsis yog tsuas yog plaub- koom nrog, rau - koom nrog, thiab yim- koom nrog rings tam sim no, tab sis kuj tseem muaj feem tseem ceeb ntawm tsib- cov tswv cuab rings. Cov tsib- cov nplhaib sib koom ua ke, sib koom ob lub tetrahedra. Paired tsib- cov tswv cuab rings tuaj yeem txuas ntxiv nrog lwm khub ntawm tsib- cov nplhaib sib koom ua ke los ntawm cov choj txuas oxygen, ua plaub- cov nplhaib sib koom ntawm cov ntsiab lus sib txuas. Yog tias cov nplhaib ntxiv txuas nrog zoo ib yam, yim- koom nrog thiab kaum ob{17}} cov nplhaib tuaj yeem tsim tau. Cov siv lead ua ntawm silicalite-1 yog tsim los ntawm ntau cov txheej txheem sib dhos ua ke thiab txuas rau hauv qhov tsim nyog. Raws li qhov tshwm sim, cov siv lead ua muaj ntau txoj kab ncaj nraim nrog txoj kab uas hla loj tshaj plaws yog cov cylindrical pores tsim los ntawm kaum ob - cov nplhaib sib koom, uas yog cov channel tseem ceeb ntawm silicalite-1. Tus ntoo khaub lig- ntu ntawm cov kab no zoo li elliptical, nrog lub axis loj ntawm 0.695nm thiab me me axis txoj kab uas hla ntawm 0.581nm. Lawv zoo li cov hlab ntim thiab sib txawv ntawm lub tawb -zoo li qhov pores ntawm A, X, thiab Y zeolites. Hauv kev xyaum, lub cylindrical pores muaj qee qhov kev sib tw, txhais tau hais tias cov khaubncaws sab nraud povtseg tsis zoo tag nrho tab sis muaj qee qhov kev hloov pauv. Yog li ntawd, qhov nruab nrab txoj kab uas hla yuav txo los ntawm 0.66nm mus rau 0.4nm. Cov kab me me tseem txuas cov channel tseem ceeb ntawm silicalite-1, tab sis lawv qhov pore loj (kwv yees li 0.39nm) yog qhov me me dhau rau feem ntau cov molecules nkag. Lawv tsuas yog ua haujlwm nkag thiab tawm txoj hauv kev hauv cov channel loj. Hais txog kev nkag mus rau molecular, cov siv lead ua ntawm silicalite-1 tuaj yeem txiav txim siab muab qhov chaw ob sab, thaum A-hom, X-hom, thiab Y-hom zeolites paub txog lawv qhov chaw peb sab.
Khoom zoo
MOR zeolite muaj qhov zoo li hauv qab no:
