Ubungozi Nokuphepha

Izimpawu Eziyingozi Xi - Irritant
Amakhodi Engozi R36/37/38 – Ukucasula amehlo, uhlelo lokuphefumula kanye nesikhumba.
R41 – Ingozi yokulimala okubi emehlweni
R37/38 – Ukucasula uhlelo lokuphefumula kanye nesikhumba.
I-R22 – Iyingozi uma igwinywe
Incazelo Yokuphepha I-S24/25 - Gwema ukuthintana nesikhumba namehlo.
S36/37/39 – Gqoka izingubo zokuzivikela ezifanele, amagilavu ​​kanye nokuvikela iso/ubuso.
S36 – Gqoka izingubo ezifanele zokuzivikela.
S26 – Uma uthintana namehlo, geza ngokushesha ngamanzi amaningi futhi ufune iseluleko sezokwelapha.

Okujwayelekile

Idatha Egunyaziwe Yedatha Eqinisekisiwe

Lo mkhiqizo yi-L-2-amino -3(B-indole) i-propionic acid. Kubalwa njengomkhiqizo omisiwe, okuqukethwe kwe-C11H12N202 akufanele kube ngaphansi kuka-99.0%.

Isici

Idatha Egunyaziwe Yedatha Eqinisekisiwe
  • Lo mkhiqizo umhlophe kuya kokuphuzi noma i-crystalline powder; Ayinaphunga.
  • Lo mkhiqizo uncibilika kancane emanzini, uncibilika kancane ku-ethanol, awuncibiliki ku-chloroform, uncibilika ku-formic acid; Incibilikisiwe kusixazululo sokuhlola i-sodium hydroxide noma i-dilute hydrochloric acid.

ukuzungeza okuthile

thatha lo mkhiqizo, ukunemba enesisindo, engeza amanzi ukuncibilikisa futhi quantitatively hlambulula ukwenza isixazululo equkethe mayelana 10mg lml ​​ngayinye, futhi unqume ngokomthetho (General rule 0621), ukuzungeza ethize kwaba -30.0 ° kuya -32.5 °.

Isingeniso

i-isomer engeyona eyemvelo ye-tryptophan

Ukuxilongwa okuhlukile

Idatha Egunyaziwe Yedatha Eqinisekisiwe
  1. amanani afanele omkhiqizo kanye nomkhiqizo wereferensi we-tryptophan kwachithwa emanzini futhi kwahlanjululwa ukuze kulungiswe isixazululo esiqukethe cishe i-10mg nge-1 ml ngayinye njengesixazululo sokuhlola nesixazululo sereferensi. Ngokuya kokuhlolwa kwesimo se-chromatographic ngaphansi kwamanye ama-amino acid, indawo nombala wendawo eyinhloko yesixazululo sokuhlola kufanele kufane naleyo yesixazululo sereferensi.
  2. I-spectrum yokumuncwa kwe-infrared yalo mkhiqizo kufanele ihambisane naleyo yokulawula (Spectrum set 946).
  • Okwedlule:
  • Olandelayo:
    • Bhala umyalezo wakho lapha futhi usithumelele wona
