METHYL 2 5-DICHLORONICOTINATE (CAS# 67754-03-4)
| Kalasi Yowopsa | ZOKWIYA |
Mawu Oyamba
Methyl 2, ndi organic pawiri ndi mankhwala formula C7H4Cl2NO2. Zotsatirazi ndizofotokozera za katundu, ntchito, kukonzekera ndi chitetezo cha pawiri:
Chilengedwe:
- methyl 2, ndi madzi opanda mtundu.
-Ili ndi fungo lopweteka kwambiri.
-Pawiriyi imasungunuka mu organic solvent monga methanol kapena dichloromethane.
-Kusungunuka kwake kumakhala pafupifupi 43-47 ° C, ndipo kuwira kwake kumakhala pafupifupi 257-263 ° C.
Gwiritsani ntchito:
- methyl 2, yomwe imagwiritsidwa ntchito ngati njira yopangira mankhwala ophera tizilombo ndi tizilombo.
-Itha kugwiritsidwanso ntchito popanga zinthu zina mu organic synthetic chemistry.
Njira Yokonzekera:
- methyl 2, ikhoza kukonzedwa ndi izi:
1. Choyamba, 2,5-dichloronicotinic acid ndi esterified ndi formic acid.
2. Zomwe zimachitika nthawi zambiri zimachitika pansi pa acidic, ndi esterifying agent, monga mowa kapena asidi catalyst, amawonjezedwa kuti apititse patsogolo.
3. Pambuyo zimene anamaliza, chandamale mankhwala anapatukana ndi kuyeretsedwa kuchokera anachita osakaniza ndi distillation kapena m'zigawo.
Zambiri Zachitetezo:
- methyl 2, ndi mankhwala omwe amakwiyitsa omwe amatha kuwononga maso, khungu ndi mucous nembanemba.
-Valani zida zodzitetezera zoyenera monga magalasi, magolovesi ndi zovala zodzitchinjiriza pogwira ndi kugwiritsa ntchito.
-Ziyenera kukhala kutali ndi moto komanso kutentha kwambiri kuti ziteteze kuopsa kwa moto ndi kuphulika.
-Posunga ndi kusamalira, tsatirani mosamalitsa njira zoyendetsera chitetezo kuti mupewe kusakanikirana ndi kukhudzana ndi zinthu zina.
-Ngati mutalowetsedwa kapena mulowetsedwa, funsani kuchipatala mwamsanga ndikupereka pepala lachitetezo kapena chizindikiro cha mankhwala.
