He aha te Dibenzo-18-karauna-6 CAS 14187-32-7?

Ko Dibenzo-18-karauna-6 te rauemi mata mō te hanga o te diaminodibenzo-18-karauna-6. He matū nui te Diaminodibenzo-18-karauna-6, ā, he rauemi mata takawaenga nui hoki mō te hanga o ngā hua o te karauna eter. Ko tana tikanga hanga ko te whakamahi i te dibenzo-18-karauna-6 hei rauemi mata, ā, mā te tauhohenga nitration me te whakaiti. Ko te tikanga whakaiti e whakamahia ana ko te tikanga whakaiti Pd/C, he mea herea e te utu nui o te whakakorikori. Ko te tikanga hanga tuku iho o te dibenzo-18-karauna-6, te rauemi mata o te diaminodibenzo-18-karauna-6, he tauhohenga reflux i raro i te tiaki hauota, he āhuatanga uaua, he mahi uaua, he huringa tauhohenga roa, he pāmahana teitei me te hua iti. Ko te hanga ultrasonic he momo tikanga hanga hou i whakawhanakehia i ngā tau tata nei. He painga o te ahunga pai, te kaha nui me te kaha uru kaha. He watea ake, he ngāwari ake te whakahaere i ngā tikanga hanga waro tuku iho. He tino māmā hoki te taputapu whakamātautau, he ngāwari hoki te whakahaere. Kei te whānui haere te whakamahinga i roto i te hanga waro.
