Nhanganyaya
Asidhi, inonziwo asidhi, inhengo yeorganic. Inotevera rondedzero yehunhu hwayo, kushandiswa, kugadzirira uye ruzivo rwekuchengetedza:
Zvakasikwa:
-Kuonekwa: asidhi ichena crystalline upfu.
-Molecular formula: C6H4BrNO2.
-Molecular uremu: 206.008g / mol.
-Kunyungudika nzvimbo: anenge 132-136 madhigirii Celsius.
-Stable pakamuri tembiricha uye soluble mune mamwe organic solvents.
Shandisa:
-asidhi inowanzoshandiswa seyakasvibiswa kana yepakati mune organic synthesis.
-Inogona kushandiswa kugadzira mutsara we nitrogen-ine heterocyclic compounds, zvakadai se pyridine uye pyridine derivatives.
-Inogonawo kushandiswa kugadzirira biologically active compounds, zvakadai semishonga yezvipembenene, mishonga uye dhayi.
Kugadzirira nzira:
-¾ asidhi inowanzogadzirirwa nekuita kwebromo-nicotinic acid. A common synthesis method ndeyekuita nicotinic acid ne bromoethanol pasi pe alkaline conditions, inoteverwa ne acidification kuti uwane chigadzirwa.
Zvekuchengetedza
-iyo asidhi inofanirwa kutevedzera general laboratory kuchengetedza maitiro panguva yekushandiswa.
-Inogona kukonzera kutsamwa kumaziso, ganda uye kufema turakiti, saka kusangana kwakananga kunofanira kudziviswa panguva yekushanda.
-mukuchengetedza uye kushandiswa kunofanira kuchenjerera kudzivisa kusangana neoxidants, yakasimba acids nezvimwe zvinhu, kuitira kuti udzivise zvinhu zvine ngozi kana maitiro.
-Kana zvichidikanwa, shanda munzvimbo ine mhepo yakanaka, kupfeka magirovhosi ekudzivirira, magirazi ekudzivirira uye masks ekudzivirira. Kana ukafemerwa kana kubuda, tsvaga rubatsiro kuna chiremba.
