Usebenzisa
Isetyenziswa njengedayi ephakathi, kwaye ikwasetyenziswa kulungiselelo lwe-fluorescent whitening agent agent intermediates, kwaye isetyenziswa kwimveliso ye-fluorescent whitening agent DT.
Indlela yokuvelisa
I-O-nitro-p-cresol ifunyenwe ngokunciphisa nge-alkali sulfide okanye i-catalytic hydrogenation.Ukuqala kwi-nitration ye-p-cresol, i-quota yokusetyenziswa kwezinto ezibonakalayo: 963kg / t yemveliso ye-p-cresol yemveliso, i-661kg / t ye-nitric acid (96%), i-2127kg / t ye-sulfuric acid (92.5%), i-2425kg / t yesoda sulfide (60%), kunye ne 20kg/t yothuthu lwesoda.
Indlela yokugcina
1. Gcina kwindawo epholileyo nengena umoya.Zigcine kude nomlilo kunye nemithombo yobushushu.Iphakheji ivaliwe.Kufuneka igcinwe ngokwahlukileyo kwi-oxidants kunye ne-acidic substances, kwaye ugweme ukugcinwa okuxubileyo.Ixhotyiswe ngeentlobo ezifanelekileyo kunye nobuninzi bezixhobo zomlilo.Indawo yokugcina kufuneka ixhotyiswe ngezinto ezifanelekileyo zokuqulatha ukuvuza.
2. Ipakishwe kwidrum yentsimbi okanye idrum yekhadibhodi efakwe kwingxowa yeplastiki.Ubunzima obunetha ngomphanda ngama-25kg okanye ama-50kg.Gcina kunye nokuthutha ngokuhambelana nemimiselo yekhemikhali ngokubanzi.
