2-(chloromethyl)-5-(trifluoromethyl)-1 3 4-oxadiazole(CAS# 723286-98-4)
Mawu Oyamba
2-(chloromethyl) -5-(trifluoromethyl) -1,3,4-oxadiazole ndi organic pawiri ndi chilinganizo C4H2ClF3N2O.
Chilengedwe:
2-(chloromethyl) -5-(trifluoromethyl) -1,3,4-oxadiazole ndi madzi achikasu otumbululuka kapena olimba. Ili ndi kukhazikika kwamafuta ambiri komanso kusakhazikika kwamankhwala. Izo sizisungunuka m'madzi kutentha kwa firiji, sungunuka mu zosungunulira zina monga ethanol ndi ether. Pawiri amatha kudziwika ndi njira monga nyukiliya maginito resonance ndi mass spectrometry.
Gwiritsani ntchito:
2-(chloromethyl) -5-(trifluoromethyl) -1,3,4-oxadiazole ili ndi phindu linalake la ntchito m'munda wa chemistry. Nthawi zambiri amagwiritsidwa ntchito ngati wapakatikati mu kaphatikizidwe ka organic kaphatikizidwe kazinthu zina. Kuphatikiza apo, imagwiritsidwanso ntchito ngati reagent yofufuza m'munda wa mankhwala ophera tizilombo ndi mankhwala.
Njira Yokonzekera:
2-(chloromethyl) -5-(trifluoromethyl) -1,3,4-oxadiazole ikhoza kupangidwa ndi njira zosiyanasiyana. Zotsatirazi ndi njira yodziwika yokonzekera:
1. Onjezani chothandizira (monga triethylamine) ku anhydrous organic reaction solvent system.
2. Onjezani kuchuluka kwa methyl 3-chloropropionate ndi methyl trifluoroformate ku zosungunulira.
3. Zomwe zimachitikazo zimachitika pa kutentha koyenera pansi pa mlengalenga, ndipo nthawi zambiri zimakhala zofunikira kutenthetsa zomwe zimasakanikirana.
4. Sefa kapena distillation kupeza mankhwala, pambuyo kuyeretsedwa koyenera ndi kuyanika kupeza choyera mankhwala.
Zambiri Zachitetezo:
2-(chloromethyl) -5-(trifluoromethyl) -1,3,4-oxadiazole nthawi zambiri imakhala yotetezeka ikagwiritsidwa ntchito ndikusungidwa bwino. Komabe, monga organic pawiri, zitha kuvulaza thanzi la anthu komanso chilengedwe. Pogwiritsira ntchito ndi kusamalira, ayenera kutsatira njira zoyenera zotetezera, ndikupewa kukhudzana mwachindunji. Malangizo okhudzana ndi chitetezo cha pawiri ayenera kuwerengedwa mosamala ndikutsatiridwa. Ngati ndi kotheka, ntchitoyo iyenera kuchitidwa motsogozedwa ndi akatswiri ogwira ntchito.
