Dicyclohexylamine

Whakamahinga

Ko te nuinga o te wā ka whakamahia te dicyclohexylamine i roto i ngā mara o ngā whakatere rapa hangai, ngā aukati waikura whakarewa, ngā matū horoi, ngā matū mara hinu, ngā rongoā me ngā patupatu. I te whanaketanga o te pūtaiao me te hangarau, kei te whanake tonu ōna tono hou, ā, ko ngā matū pai kua angitu te hanga he hua hou me ngā tūmanako whanaketanga.

te whakarite

He pūwero moenga-pūmau te tauhohenga whakahinuhinu wai, ā, ko te whānui o roto he 20 mm. He whakahinuhinu kaha-nui te whakakorikori e ahu mai ana i te nikara, ā, he 15 mL te rahinga pumau. Kei roto i te rohe isothermal o te tauhohenga te whakakorikori. Ko te rahi o te matūriki he 20 mata ki te 40 mata. Ko te ōwehenga papatipu o ia huānga whakarewa i roto i te whakakorikori ko: Ni:Al:Mo=85:5:5. Ka whakaurua te dicyclohexylamine mata me te hauwai mai i te taha o runga o te tauhohenga hei mahi i te tauhohenga whakahinuhinu wai. Ka kohia tonutia ngā hua mai i te pito o raro o te tauhohenga, ā, ka tātarihia. Ka whakahokia mai te hauwai i muri i te wehenga hau-wai, ā, ka whakamahia anō. Ko te hanganga (ōrau taumaha) o te dicyclohexylamine mata i roto i te Chemicalbook he 10.15% cyclohexylamine, 5.11% aniline, 79.91% dicyclohexylamine, 0.31% dicyclohexyleneamine, 0.1% cyclohexylaniline, me te 1.88% cyclohexeneaniline. %. Ngā āhuatanga tauhohenga: 180°C, 3.5MPa, tere wāhi rōrahi wai 0.2h-1, ōwehenga hauwai ki te hinu 1000. Te tohatoha hua i muri i te hydrorefining: cyclohexylamine 5.76%, aniline 0%, dicyclohexylamine 93.03%, dicyclohexyleneamine 0%, cyclohexylaniline 0.01%, cyclohexeneaniline 0%.

Ngā Āhuatanga Matū

He wai hinuhinu mārama, kore tae, he kakara haukini kaha. He wairewa pakupaku ki te wai, ka taea te whakaranu ki ngā whakarewa waro.

Tikanga whakaputa:

Mā te whakamahi i te aniline hei rauemi mata, ka whakamahia te hauwai i te pāmahana teitei me te pēhanga teitei i te aroaro o tētahi whakakorikori hei hanga i te dicyclohexylamine.
