Kugadzira Nzira
Inoshandiswa sedhayi yepakati, uye zvakare inoshandiswa mukugadzirira fluorescent whitening agent dhayi yepakati, uye inoshandiswa mukugadzira fluorescent whitening agent DT.
Kugadzira Nzira
Uchishandisa p-chlorophenol seyakagadzirwa, 2-nitro-p-chlorophenol inogona kugadzirwa kuburikidza ne nitration, yozoderedzwa kuita p-chloro-o-aminophenol.
(1) Kugadzirwa kwe2-nitro-p-chlorophenol: Kushandisa p-chlorophenol seyakagadzirwa, nitrification ine nitric acid.Wedzera iyo distilled p-chlorophenol zvishoma nezvishoma mutangi yakamutswa ine 30% nitric acid, chengetedza tembiricha iri pa25-30.℃, simbisa kwemaawa maviri, wedzera ice kuti itonhorere kusvika pasi pe20℃, precipitate, sefa, uye geza keke yekusefa kuCongo Red, chigadzirwa 2-nitrop-chlorophenol chinowanikwa.
(2) Pane nzira mbiri dzekudzikisa 2-nitro-p-chlorophenol.Imwe ndeyekuderedza ne sodium disulfide.Kutanga, 30% sodium hydroxide solution uye sulfur powder inoshandiswa kugadzira sodium disulfide solution, uye 2-nitro-p-phenol inowedzerwa muchiyero chekuita pa95-100.°C, uye kuita kwapera.Mushure mekupisa kunopisa, iyo filtrate inogadziriswa nekubika soda mvura, yakanyoroveswa kusvika makumi maviri°C, yakapepetwa, uye keke resefa rinogezwa kusarerekera kuti riwane chigadzirwa chakapedzwa 2-nitro-p-chlorophenol.
Yechipiri ndiyo nzira yekuderedza hydrogenation.Muhupo hwenickel catalyst, iyo aqueous suspension ye2-nitro-p-chlorophenol inogadziridzwa kuita pH = 7 ine sodium dihydrogen phosphate hydrate uye sodium hydroxide aqueous solution pane hydrogen pressure ye4.05Mpa uye Hydrogenation kuderedza pa60.°C. Mushure mekuita kwapera, sunungura kumanikidzwa, shandura nenitrogen, kupisa kusvika ku95°C, gadzirisa pH = 10.7 ine sodium hydroxide, wedzera activated kabhoni uye diatomaceous pasi, kurudzira nesimba, uye sefa.Iyo filtrate yakagadziridzwa kuita pH = 5.2 (20°C) ine concentrated hydrochloric acid, yakanyoroveswa kusvika ku0°C, yakapepetwa, yakaomeswa, uye yakarapwa nesodium bisulfite.Dzokorora oparesheni yacho kana, wobva waisa pa2.67kpa, unganidza zvikamu zvakatenderedza makumi masere.°C, woomesa kuti uwane chigadzirwa negoho re97.7%.
The Main Application
Iko kushandiswa kukuru kwep-chloro-o-aminophenol kunenge dhayi yepakati, yekugadzira acid mordant RH, acid complex violet 5RN uye reactive dhayi, nezvimwewo, uye zvakare nekugadzirira kweiyo raw material chlorzoxazone.
Packaging, Kuchengeta uye Kutakura
Ikemikari ine ngozi, uye yakaputirwa mumadhiramu esimbi anorema 25kg, uye imba yekuchengetera zvinhu inopinzwa mhepo, inodzikira uye yakaoma, uye inodzivirirwa kubva kuzuva rakananga.Ramba uri kure nezvinopisa moto, uye chengeta uye kutakura zvakaparadzana kubva kumaasidhi, oxidants, zvekudya zvinowedzera, uye oxidants.
