Kugadzira Nzira
O-nitro-p-cresol inowanikwa nekuderedza nealkali sulfide kana catalytic hydrogenation.Kutanga kubva kunitrate yep-cresol, iyo mbishi yekushandisa quota: 963kg/t yep-cresol industrial product, 661kg/t yenitric acid (96%), 2127kg/t yesulfuric acid (92.5%), 2425kg/t soda sulfide (60%), uye 20kg/t yesoda ash.
Kuchengeta Nzira
1. Chengetedza muimba yekuchengetera inotonhorera, ine mhepo.Ramba kure nemoto nekupisa.Iyo package yakavharwa.Inofanira kuchengetwa zvakasiyana kubva kune oxidants uye acidic zvinhu, uye kudzivisa kusanganiswa kuchengetedza.Yakashongedzerwa nemhando yakakodzera uye huwandu hwemidziyo yemoto.Nzvimbo yekuchengetera inofanirwa kunge yakashongedzerwa nezvinhu zvakakodzera kuti ive nekudonha.
2. Yakaiswa mudhiramu resimbi kana makadhibhokisi akaiswa nepurasitiki.Huremu hwemambure padhiramu i25kg kana 50kg.Chengetedza uye kutakura maererano nemitemo yakawanda yemakemikari.
