I-Triphenylphosphine: ilungu lama-phosphine e-tertiary
I-Triphenylphosphine (TPP) iyilungu lama-phosphine asezikhundleni eziphezulu, okuyi-phosphane, lapho ama-hydrogen amathathu ethathelwa indawo ngamaqembu e-phenyl. Inendima njenge-ejenti yokunciphisa kanye ne-NMR chemical shift reference compound. Iyi-ligand ebalulekile esetshenziswa ekusabeleni kwe-Wittig kokwenziwa kwe-alkene. Lokhu kusabela kuhilela ukwakheka kwe-alkyliden-etriphenylphosphoranes kusukela esenzweni se-butyllithium noma esinye isisekelo ku-quarternary halide. I-Triphenylphosphine isetshenziselwa ukuhlanganisa ama-organic compounds ngenxa ye-nucleophilicity yayo kanye nohlobo lokunciphisa.

Ukusetshenziswa
I-Triphenylphosphine iqala ngokuhlanganiswa ne-oleum ukuze yakhe i-trisulfonic acid.
I-Triphenylphosphine ingasetshenziswa ekwakhiweni kwe-Wittig. Iyi-ligand ejwayelekile ekuhlaziyweni okufanayo.
I-Triphenylphosphine isetshenziswa ekwakhiweni kwe-organophosphorus intermediate, i-trimethyl phosphite ngendlela yokushintshana kwe-ester. Bese kuthi uchungechunge lwezibulala-zinambuzane ze-organophosphorus ezifana ne-dichlorvos, i-monocrotophos kanye ne-phosphamidon lungatholakala kabanzi.
Ngaphezu kwalokho, ingasetshenziswa njengeziqinisi ekwakhiweni kwerabha nama-resin, ama-antioxidants ku-polyvinyl chloride, kanye nezinto zokusetshenziswa ekwakhiweni kwama-alkyd resin nama-polyester resin.
Ukupakisha Nokuthumela

Ingaletha ngolwandle nangomoya
Gcina futhi ugcine
Isikhathi sokuphila: Izinyanga ezingama-24 kusukela ngosuku lokwenziwa kwento epakishweni lokuqala elingavulwanga, igcinwe endaweni epholile neyomile kude nokukhanya kwelanga okuqondile, amanzi.
Indawo yokugcina izinto enomoya, Ukomisa okuphansi kwezinga lokushisa, Ihlukaniswe nama-oxidants, ama-acid.
