Nhanganyaya
Asidhi (asidhi) inhengo yeorganic ine kemikari formula C6H4ClNO2.
Zvakasikwa:
Asidhi ichena kusvika kuchiedza checrystalline crystalline yakasimba ine kunhuhwirira kwakakosha. Inonyungudika mune mamwe organic solvents, senge ethanol, dimethyl sulfoxide uye dichloromethane, asi ine yakaderera solubility mumvura. Yakagadzikana mumhepo uye inoora pakupisa kukuru.
Shandisa:
Acid chinhu chakakosha chepakati chepakati, chinoshandiswa zvakanyanya mukugadzirwa kwemamwe ma organic compounds. Inogona kushandiswa mukugadzirira kwemishonga yezvipembenene, zvinodhaka, dhayi uye coordination compounds.
Kugadzirira nzira:
Acid inogona kugadzirwa nenzira dzakasiyana siyana, nzira dzinowanzo shandiswa dzinosanganisira mbiri dzinotevera:
1. 2-picolinic acid chloride inobatwa ne chloroacetic acid kuti ibudise chigadzirwa chakanangwa nerubatsiro rwechigadziri uye pasi pemamiriro akakodzera.
2. react 2-pyridyl methanol ne carbonic acid chloride, uye ipapo hydrolyze ne acid kuti iwane asidi.
Zvekuchengetedza
Iyo toxicity yeasidhi yakaderera, asi zvichiri kudikanwa kuterera kune yakachengeteka kushanda. Dzivisa kusangana zvakananga neganda, maziso uye turakiti rekufema, uye pfeka magirovhosi ekudzivirira, magirazi uye masks kana zvichidikanwa. Dzivisa kusangana neoxidizing agents uye zvinhu zvinopisa panguva yekushandisa uye kuchengetedza. Inofanira kuchengetwa munzvimbo yakaoma, ine mhepo yakanaka, kure nemoto. Kana ukamwiwa kana kufemerwa, tsvaga kurapwa nekukasika.
