Tikanga Whakaputa
Ka whakamahia hei takawaenga waikano, ka whakamahia hoki i roto i te whakarite o nga kaiwawao waikano a te kaikorero, ka whakamahia ki te hanga o te kaihoko DT.
Tikanga Whakaputa
Ma te whakamahi i te p-chlorophenol hei rauemi mata, ka taea te hanga i te 2-nitro-p-chlorophenol na roto i te whakamaoritanga, katahi ka whakahekehia hei hanga p-chloro-o-aminophenol.
(1) Te whakaputanga o te 2-nitro-p-chlorophenol: Te whakamahi i te p-chlorophenol hei rauemi mata, te nitrification me te waikawa nitric.Āta tāpirihia te p-chlorophenol kua whakamarohia ki roto i te tank whakakorikori me te 30% waikawa nitric, kia mau te pāmahana ki te 25-30℃, whakaohokia mo te 2 haora, tāpirihia te huka kia whakamatao ki raro i te 20℃, tohe, tātari, ka horoi i te keke tātari ki Congo Whero, ka whiwhi te hua 2-nitrop-chlorophenol.
(2) E rua nga tikanga mo te whakaheke i te 2-nitro-p-chlorophenol.Ko tetahi ko te whakaheke me te konutai disulfide.Tuatahi, ka whakamahia te 30% wairewa konutai waikawa me te paura whanariki hei hanga wairewa konutai disulfide, ka taapirihia te 2-nitro-p-phenol kia rite ki te tauhohe i te 95-100°C, ka mutu te tauhohenga.I muri i te tātari wera, ka whakakorehia te filtrate ki te wai houra tunutunu, ka whakamatao ki te 20°C, tātarihia, ka horoia te keke tātari ki te korekore ki te whiwhi i te hua oti 2-nitro-p-chlorophenol.
Ko te tuarua ko te tikanga whakaheke hauwai.I te aroaro o te whakakorikori nickel, ka whakatikahia te whakatārewatanga wai o te 2-nitro-p-chlorophenol ki te pH=7 me te konutai dihydrogen phosphate hydrate me te konutai waiwai wairewa wai i te pehanga hauwai o 4.05Mpa me te whakaiti i te Hydrogenation i te 60°C. Kia oti te tauhohenga, tukuna te pehanga, whakakapi ki te hauota, whakamahana ki te 95°C, whakatika pH=10.7 ki te konutai waihā, tāpirihia te waro whakahohe me te whenua diatomaceous, te whakaoho kaha, me te tātari.I whakatikahia te filtrate ki te pH=5.2 (20°C) me te waikawa pūhaumāota, whakamatao ki te 0°C, ka tātarihia, ka whakamarokehia, ka tukuna ki te konutai bisulfite.Whakahokia te mahi kia wha nga wa, ka whakamakuku ki te 2.67kpa, kohikohia nga hautau tata ki te 80°C, ka whakamaroke kia whiwhi i te hua me te 97.7%.
Te Tono Matua
Ko te whakamahinga matua o te p-chloro-o-aminophenol hei takawaenga waikano, mo te whakarite o te waikawa mordant RH, waikawa matatini 5RN me nga waikano reactive, me etahi atu, me te whakarite hoki i te chlorzoxazone raw rauemi.
Te Whakapaipai, te Rokiroki me te Whakawhitiwhiti
He matū kino tenei, a he mea takai ki roto i te 25kg pahu rino, me te whare putunga he hau, he iti te pāmahana me te maroke, ka tiakina mai i te ra tika.Mawehe atu i nga puna wera o te ahi, ka penapena me te kawe motuhake mai i nga waikawa, nga waiora, nga taapiri kai, me nga waiora.
