-Solubility: Inonyungudika zvishoma mumvura, inonyungudika mune zvakajairika organic solvents senge ethanol, ether uye benzene
Shandisa:
Inowanzoshandiswa sepakati mune organic synthesis uye inogona kushandiswa kugadzirira mamwe organic komisheni. Inogona kushandiswa mumishonga synthesis, pesticide synthesis, uye mumaindasitiri edhayi nependi.
Kugadzirira Nzira: Kugadzirira kwe
kazhinji inoitwa nematanho anotevera:
1. React p-methylbenzonitrile nebromine pasi pemamiriro ekugadzirisa akakodzera kuti ibudise phenol.
Zvekuchengetedza
-Iyo inogona kuve yakasanganiswa uye inofanirwa kubatwa nekuchenjerera.
-Panguva yekushanda, kutarisirwa kunofanira kutorwa kuti usapinda zvakananga neganda, maziso uye nzira yekufema.
-Pfeka midziyo yekudzivirira yakakodzera, senge magurovhosi erabhoritari uye magirazi.
-Inofanirwa kushandirwa munzvimbo ine mhepo inofefetera uye kudzivirira kupinza mhute kana guruva.
-Kana ukafemerwa kana ukapinzwa nekukanganisa, tsvaga rubatsiro rwekurapa nekukasira uye ratidza mudziyo kana label kuti utarise.
Ndokumbira utarise kuti chero chemakemikari zvinhu zvinofanirwa kushandiswa pasi pemamiriro akakodzera emurabhoritari uye kutevedzera nzira dzakachengeteka dzekushanda.
