Nhanganyaya
3-choro-5-(trifluoromethyl)pyridine is an organic compound ine chemical formula C≡H₂ ClFΛ N. Imvura isina ruvara kusvika kune yakachenuruka uye inonhuwa. Iyi inotevera rondedzero yechimiro, kushandiswa, kugadzirira uye chengetedzo ruzivo rwe3-choro-5-(trifluoromethyl)pyridine:
Zvakasikwa:
-Kuwanda: 1.578 g/mL
-Kubikira nzvimbo: 79-82 ℃
-Kunyungudika: -52.5 ℃
-Solubility: Soluble in organic solvents senge ethanol, ether uye dichloromethane, inonyungudika zvishoma mumvura.
Shandisa:
-Sema reagents uye epakati mune organic synthesis, anoshandiswa mukugadzirisa kwemishonga yezvipembenene, zvinodhaka uye mamwe organic komisheni.
-Kutsvagisa mumunda wemishonga, senge mukugadzirwa kwemishonga inorwisa cancer uye biomarkers.
Kugadzirira nzira:
3-chloro-5-(trifluoromethyl)pyridine inogona kugadzirwa nenzira mbiri dzinotevera:
1. Kushandisa pyridine sechinhu chakasvibiswa, chlorination reaction inoitwa pamberi pehydrochloric acid, uye ipapo trifluoromethylation reaction inoitwa pamberi pe sodium trifluoromethylate.
2. Kushandisa 3-picolinic acid sechinhu chakasvibiswa, chlorination reaction inoitwa pamberi pe thionyl chloride, uye ipapo trifluoromethylation reaction inoitwa pamberi pe trifluoromethyl mercaptan.
Zvekuchengetedza
- 3-chloro-5-(trifluoromethyl)pyridine inogumbura uye inogona kukonzera kushatirwa mukubata neganda nemaziso. Izvo zvinodikanwa kupfeka matanho ekudzivirira akakodzera paunenge uchishandisa, sekupfeka magirazi ekudzivirira, magirovhosi uye zvipfeko zvekudzivirira.
-Dzivisa kufema mhute yaro uye ona kuti kuvhiya kunoitwa munzvimbo ine mhepo inofefetera.
-Paunenge uchichengeta, chengeta mumudziyo wakavharwa, kure nemoto uye oxidizing agents.
-Pakurasa tsvina, ibate uye uirase maererano nemitemo yenzvimbo.
-Ndokumbira utarise iyo yakakodzera Safety Data Sheet (SDS) kuti uwane rumwe ruzivo rwekuchengetedza.
