Umenzi Ixabiso Elihle P-TOLUENESULFONYLISOCYANATE (PTSI) CAS 4083-64-1

inkcazo emfutshane:

I-P-TOLUENESULFONYLISOCYANATE (PTSI) yi-isocyanate esebenzayo enye. I-P-TOLUENESULFONYLISOCYANATE (PTSI) inomsebenzi ophezulu kwaye inokusabela kwi-diisocyanates eziqhelekileyo, ezifana ne-TDI kunye ne-HDI, kunye namanzi kwi-polyols kunye nezinyibilikisi. I-carbamate ephumayo ayinyusi i-viscosity yenkqubo. Ingxaki kukuba ubuthi be-oxazolidine kunye nezinye izinto ezikhupha amanzi emzimbeni bukhulu; I-P-TOLUENESULFONYLISOCYANATE (PTSI) isabela namanzi ukuvelisa i-carbon dioxide kunye ne-toluenesulfamide, ngoko ke i-P-TOLUENESULFONYLISOCYANATE (PTSI) ayinakusetyenziswa ngokuthe ngqo kwiifomyula zepeyinti kwaye isetyenziswa ngokubanzi ekupheliseni amanzi emzimbeni ngaphambi kokuphelelwa ngamanzi emzimbeni. Ukususa i-1g yamanzi kwisinyibilikisi, malunga ne-12g ye-PTSI iyimfuneko ngokwethiyori, kodwa ubungakanani bokwenyani kufuneka bube ngaphezulu kunobu.

Ukusetyenziswa kwe-PTSI

I-1.p-Toluenesulfonyl isocyanate yi-reagent esetyenziselwa ukulungisa i-acetylated syn-1,2-diols, i-1 oxazolidin-2-ones, i-2 2,3-diamino acids, i-3 kunye ne-N-tosylcarbonamides.4

2. Yi-reagent esetyenziselwa ukulungiselela i-syn-1,2-diols e-acetylated, i-oxazolidin-2-ones, i-2,3-diamino acids, kunye ne-N-tosylcarbonamides. I--Toluenesulfonyl isocyanate isetyenziswe njenge-reagent ye-derivatization ekumiselweni kwe-3-α-hydroxy tibolone kwi-plasma yomntu yi-LC-MS/MS. Ikwasetyenziswa kwi-reagent ye-derivatization kuhlalutyo olulinganayo lwe-diethylene glycol kunye ne-propylene glycol kwiimveliso zamayeza yi-HPLC kwaye njenge-reagent ekulungiseleleni i-syn-1,2-diols e-acetylated, i-oxazolidin-2-ones, i-2,3-diamino acids kunye ne-N-tosylcarbonamides.

Imigaqo yokuhlawula: TT/BL yetyala kunye nezinye izinto ezixoxiswana ngazo.
