Umxholo wesinyithi waseTshayina 15529-49-4 10.5% tris(triphenylphosphine)ruthenium(ii) chloride Umvelisi kunye noMzi-mveliso

15529-49-4 umxholo wesinyithi 10.5% tris(triphenylphosphine)ruthenium(ii) chloride

Inkcazo emfutshane:

Iikhatalyst zesinyithi ezixabisekileyo ziintsimbi ezintle ezisetyenziswa kakhulu kushishino lweekhemikhali ngenxa yokukwazi kwazo ukukhawulezisa inkqubo yeekhemikhali. Igolide, i-palladium, iplatinum, i-rhodium, kunye nesilivere zezinye zemizekelo yeentsimbi ezixabisekileyo.

Iintshayelelo

Iikhatalyst zesinyithi ezixabisekileyo zisinyithi ezixabisekileyo ezisetyenziswa kakhulu kushishino lweekhemikhali ngenxa yokukwazi kwazo ukukhawulezisa inkqubo yeekhemikhali. Igolide, i-palladium, iplatinum, i-rhodium, kunye nesilivere zezinye zemizekelo yeesinyithi ezixabisekileyo. Iikhatalyst zesinyithi ezixabisekileyo zezo ziquka amasuntswana esinyithi axabisekileyo asasazeke kakhulu axhaswe kwindawo ephezulu efana nekhabhoni, i-silica, kunye ne-alumina. Ezi khatalyst zinezicelo ezininzi kumashishini ahlukeneyo. Ikhatalyst nganye yesinyithi exabisekileyo ineempawu ezizodwa. Ezi khatalyst zisetyenziselwa ikakhulu ukusabela kokwenziwa kwezinto eziphilayo. Izinto ezifana nemfuno ekhulayo evela kumacandelo okusetyenziswa kokugqibela, iinkxalabo zokusingqongileyo kunye neziphumo zazo zomthetho ziqhuba ukukhula kwemarike.

Iimpawu ze-catalysts zesinyithi esixabisekileyo

1. Umsebenzi ophezulu kunye nokukhetha kweentsimbi ezixabisekileyo kwi-catalysis

Iikhatalyst zesinyithi ezixabisekileyo zenziwe ngamasuntswana esinyithi axabisekileyo asasazeke kakhulu kwizixhobo ezinomphezulu ophezulu njengekhabhoni, isilika, kunye ne-alumina. Amasuntswana esinyithi aqhelekileyo afunxa i-hydrogen kunye ne-oxygen ngokulula emoyeni. I-hydrogen okanye i-oxygen isebenza kakhulu ngenxa yokufunxa kwayo i-dissociative nge-d-electron evela kwiqokobhe leeathom zesinyithi ezixabisekileyo.

2. Uzinzo

Iintsimbi ezixabisekileyo zizinzile. Azikwazi ukwenza ii-oxide ngokulula ngokuzitshisa. Ii-oxide zeentsimbi ezixabisekileyo, kwelinye icala, azizinzile kangako. Iintsimbi ezixabisekileyo azinyibiliki lula kwisisombululo se-asidi okanye se-alkaline. Ngenxa yozinzo oluphezulu lobushushu, i-catalyst yentsimbi exabisekileyo isetyenzisiwe njengee-catalysts zokucoca igesi yokukhupha umoya kwiimoto.
