Isingeniso

I-2-Mercapto-5-(trifluoromethyl)pyridine iyinhlanganisela yezinto eziphilayo enefomula yamakhemikhali ethi C6H4F3NS. Izici zayo eziyinhloko zimi kanje:

 

1. Ukubukeka: uketshezi oluqinile olungenambala noma oluphuzi olukhanyayo;

2. ukunyibilika: ukuncibilika otshwaleni, i-ether nezinye izincibilikisi eziphilayo, ezingancibiliki emanzini;

3. iphunga: inephunga elikhethekile le-thiol.

 

I-2-Mercapto-5-(trifluoromethyl)pyridine inokusetshenziswa okuyinhloko okulandelayo:

 

1. i-catalyst: ingasetshenziswa njenge-catalyst in organic synthesis reaction, iqhaza ekuhlanganiseni kwe-thiol, i-carboxylic acid ne-ketone;

2. Ukuhlaziywa kwamakhemikhali: kungasetshenziselwa ukukhishwa kwesigaba esiqinile, ikholomu yechromatography nezinye izindlela zokuhlaziya amakhemikhali;

3. I-flame retardant: njenge-flame retardant ku-organic synthesis, isetshenziselwa ukuthuthukisa ukumelana nokushisa kwezinto;

4. I-organic synthesis: ingasetshenziselwa ukuhlanganiswa kwezibulala-zinambuzane, odayi be-fluorescent nezinye izinhlanganisela eziphilayo.

 

I-2-Mercapto-5-(trifluoromethyl)pyridine ilungiswa ikakhulukazi ngezindlela ezilandelayo:

 

1. etholwe ngokusabela i-3-mercaptopyridine ne-trifluoromethyl compound;

2. usebenzisa ama-chloropyridine amabili kanye ne-mercapto amino hydrofluoride reaction synthesis.

 

Uma usebenzisa i-2-Mercapto-5-(trifluoromethyl)pyridine, udinga ukunaka imininingwane yokuphepha elandelayo:

 

1. Inhlanganisela ingase ibe yingozi empilweni lapho ithinta isikhumba, amehlo noma ukuhogela, futhi ukuthintana okuqondile kufanele kugwenywe;

2. sebenzisa inqubo yokugqoka izinto zokuzivikela ezifanele, njengamagilavu, izibuko, njll;

3. gwema ukuthintana namakhemikhali anjengama-oxidants kanye ne-hydrofluoric acid ukuze ugweme ukusabela okuyingozi;

4. indawo yokugcina impahla kufanele ibekwe endaweni epholile, enomoya omuhle, kude nomlilo kanye nemithombo yokushisa;

5. ekusetshenzisweni nasekugcinweni kwenqubo kufanele ihambisane ngokuqinile nezinqubo zokuphepha ezifanele ukuze kuqinisekiswe ukuphepha.
