Mawu Oyamba
Acid (acid) ndi organic pawiri ndi mankhwala formula C6H4ClNO2.
Chilengedwe:
Acid ndi woyera mpaka kuwala wachikasu crystalline olimba ndi fungo lapadera. Imasungunuka mu zosungunulira za organic, monga ethanol, dimethyl sulfoxide ndi dichloromethane, koma imakhala ndi kusungunuka kochepa m'madzi. Imakhala yokhazikika mumlengalenga ndipo imawola pakatentha kwambiri.
Gwiritsani ntchito:
Acid ndi yofunika organic wapakatikati, amene chimagwiritsidwa ntchito kaphatikizidwe ena organic mankhwala. Ikhoza kugwiritsidwa ntchito pokonza mankhwala ophera tizilombo, mankhwala osokoneza bongo, utoto ndi kugwirizana kwa mankhwala.
Njira Yokonzekera:
Acid ikhoza kupangidwa ndi njira zosiyanasiyana, zomwe zimagwiritsidwa ntchito nthawi zambiri zimaphatikizapo izi:
1. 2-picolinic acid chloride imayendetsedwa ndi chloroacetic acid kuti ipange mankhwala omwe akuwongolera mothandizidwa ndi chothandizira komanso pansi pamikhalidwe yoyenera.
2. amachita 2-pyridyl methanol ndi carbonic acid kolorayidi, ndiyeno hydrolyze ndi asidi kupeza asidi.
Zambiri Zachitetezo:
Kawopsedwe wa asidi ndi otsika, komabe m'pofunika kulabadira otetezeka ntchito. Pewani kukhudza khungu, maso ndi kupuma, ndipo valani magolovesi oteteza, magalasi ndi masks ngati kuli kofunikira. Pewani kukhudzana ndi oxidizing agents ndi zinthu zoyaka moto mukamagwiritsa ntchito ndikusunga. Iyenera kusungidwa pamalo owuma, olowera mpweya wabwino, kutali ndi moto. Mukalowetsedwa kapena kupumira, pitani kuchipatala mwamsanga.
