Mawu Oyamba
Acid (asidi) ndi organic pawiri. Zotsatirazi ndizofotokozera za chikhalidwe chake, kagwiritsidwe ntchito, kapangidwe ndi chitetezo:
Chilengedwe:
-Maonekedwe: Mawonekedwe ofala ndi oyera mpaka oyera oyera a kristalo.
- Malo osungunuka: Malo osungunuka a pawiri nthawi zambiri amakhala pa 100-105 ° C.
-Kusungunuka: Kumakhala ndi kusungunuka kwabwino muzitsulo zina za polar, monga ethanol, dimethyl sulfoxide, ndi zina zotero. Koma kusungunuka m'madzi kumakhala kochepa.
Gwiritsani ntchito:
-asidi ndi gawo lomwe limagwiritsidwa ntchito kwambiri pakupanga organic synthesis. Itha kugwiritsidwa ntchito popanga mitundu yosiyanasiyana ya pyrazole kapena pyrimidine.
-Pawiriyi itha kugwiritsidwanso ntchito ngati zopangira m'munda wamankhwala.
Njira Yokonzekera:
-Kukonzekera kwa asidi kungapezeke mwa kuchitapo kanthu. Njira yodziwika bwino yopangira ndikuyamba kuchokera ku pyrazole ndipo potsirizira pake kuphatikizira chandamale chandamale kudzera muzotsatira zamankhwala.
-Njira yeniyeni yokonzekera ingasiyane malinga ndi cholinga cha kafukufuku, kupezeka kwa deta, ndi zina zotero, ndipo mukhoza kutchula zolemba zoyenera za sayansi kapena zovomerezeka kuti mudziwe zambiri.
Zambiri Zachitetezo:
- asidi nthawi zambiri imakhala yokhazikika yogwiritsidwa ntchito moyenera ndikusungidwa. Komabe, monga momwe zimakhalira ndi mankhwala aliwonse, amafunikabe kusamaliridwa.
-Zitha kukhala zokwiyitsa, ndiye ziyenera kusamala kuti musakhudze khungu, maso kapena kupuma.
-Pogwiritsa ntchito ndikugwira, tsatirani njira zolondola za labotale ndi njira zodzitetezera, ndikuwonetsetsa kuti mpweya wabwino uzikhala woyenera.
