Nga korero
| matū matū pararopi rawa | Ko te methylamine, e mohiotia ana ko te methylamine me te aminomethane, he matū matū tino nui me nga takawaenga, i te pāmahana rūma me te pehanga hau mo te hau kore e mura, te kukū teitei, te whakaheke ranei i te haukini, me te haukini kaha. Te kakara ika i te iti rawa o te kukū. Ka whakarewahia ki te wai, ka whakarewahia ki te waihano, te etera. He ngawari ki te tahu, hanga he ranunga pahū ki te hau, te rohe pahū: 4.3% ~ 21%. He kawakore ngoikore, kawakore atu i te haukinia, me te waikawa parakore hei whakaputa i nga tote wairewa wai. Ka whakahiatohia mai i te methanol me te haukinia i raro i te mahi o te pāmahana teitei me te pehanga teitei me te whakakorikori, ka taea hoki te whakarite ma te whakawera formaldehyde me te haukinia pūhaumāota ki te 300 ℃ i raro i te mahi a te zinc chloride. Ka taea te whakamahi i te Methylamine ki te hanga pesticides, ho'oraa, rapa vulcanization whakatere, waikano, pahū, hiako, hinu, surfactants, resins whakawhiti katote, strippers peita, paninga me tāpiritanga. He rauemi mata nui mo te hanga pesticide Dimethoate, carbaryl me te chlordimeform. Ko te paitini inhalation methylamine he karaehe paitini iti, te nui o te kukū e whakaaetia ana i te rangi 5mg/m3(0.4ppm). He pirau, he whakapataritari ki nga kanohi, kiri me nga kiri mucous. Mena ka tuwhera te mura o te ahi, ka tupono te ngingiha na te wera nui, ka pakaru nga porotaka me nga taputapu ka pahū. |
| Awhina Tuatahi mo te paihana | Ko te methylamine he karaehe paitini reo me te riri kino me te pirau. I roto i te tukanga whakaputa me te wa e kawe ana, na te rerenga ohorere, ka pa ki te pawera kino. Ka taea te ngongo i tenei hua i roto i te rewharewha, ka uru te wairewa ki roto i te kiri, ka paihana te tote i te horomia ohorere. He kaha te whakaihiihi o tenei hua ki runga i nga kanohi, te waahanga manawa o runga, te kiri me te mucosa. Ko te whakangohanga o te kukū teitei ka taea te pakaru i nga ngongo. Ko nga keehi kino ka pa mai te edema pulmonary, te mate manawa me te mate. Heoi, karekau he keehi o te paihana nahanaha i panuitia ki te kainga me ki waho. Ko nga puhui methylamine wai ka kaha te riri me te waikura, ka wera te kanohi me te kiri. Ko te 40% o te wairewa wai methylamine ka pa te mamae o te kanohi, te photophobia, te roimata, te Conjunctival Congestion, te pupuhi o te kamo, te edema o te kiri me te whewhe papa, ka mau nga tohu mo te 1 ki te 2 wiki. Ko te rongo mo te wa roa ki te iti o nga puhui methylamine, ka maroke nga kanohi, te ihu, te korokoro me te mamae. [mehua awhina tuatahi] i te wa e pa ana te kiri, tangohia tonu nga kakahu kua poke, ka horoi marie ki te nui o te wai rere, 0.5% te waikawa citric ka horoi i te kiri, i nga kiri mucous me nga hopi. ka poke nga karu, me hiki nga kamo, ka horoi ki te wai rere, ki te tote ranei mo te 15 meneti neke atu, katahi ka tirotirohia ma te paninga fluorescein. Mena kua whara te kiri, me toro atu ki te tohunga kanohi. mo te hunga kua hongi i te hau monomethylamine, me tere te whakarere i te waahi ka neke ki tetahi waahi hau hou kia kore ai e arai te ara manawa. Ko te mate pukupuku o nga turoro me hoatu he hāora inhalation, i muri i te maimoatanga, ka tukuna te manawanui ki te hohipera mo te maimoatanga ohorere. |
| kaupapa | ka whakamahia hei rauemi mata pararopi mo te pesticide, ho'oraa, pueru me etahi atu ahumahi, whakamahia hoki i roto i te wai pahū wai. whakamahia hei whakarewa me te whakamatao whakamahia hei matū matū matū taketake, whakamahia hoki ki te pesticide, ho'oraa, pueru me etahi atu ahumahi whakamahia rite surfactant, aukati polymerization me whakarewa, whakamahia hoki i roto i te whakahiato waro me te tā me te ahumahi tae mo te whakahiatotanga o nga pesticides pai, te rongoa, te waikano, nga mea kakara, me era atu, mo te electrolysis, electroplating monomethylamine ko te aliphatic amine organic matū rawa matū rawa, e whakamahia whānuitia ana i roto i te hanga o pesticides, a ka taea te whakamahi ki te synthesize N- methyl chloroacetamide, ko te takawaenga o te organophosphorus insecticide dimethoate me te omethoate; monocrotophos takawaenga α-chloroacetylmethanamine; Ko te Carbamoyl chloride me te methyl isocyanate hei takawaenga mo nga pepeke ngarara carbamate; Me etahi atu momo pesticide penei i te monoformamidine, Amitraz, benzenesulfonon, me etahi atu, ka whakamahia ano hoki i roto i te rongoa, te rapa, te tae, te ahumahi hiako me nga taonga whakaahua. Ko te methylamine he maha nga waahanga ahumahi. Ka taea te whakamahi i te Methylamine hei rongoa (whakahohenga, kawheine, ephedrine, me etahi atu), pesticide (carbaryl, dimethoate, chloramidine, me etahi atu), tae (alizarin intermediate, anthraquinone intermediate, me etahi atu), te pupuhi me te wahie (te pupuhi wai, te monomethhydrazine. , etc.), surfactants, accelerators, and raw materials such as rapa aids, photographic chemicals and whakarewa. He takawaenga mo te hanga matū ahuwhenua me te rongoa mo te hanga N-methylpyrrolidone (whakarewa). |
| tikanga whakaputa | i roto i te ahumahi, ka whakahiatohia te methylamine mai i te methanol me te haukini i te teitei o te pāmahana ma te kaitahuri e mau ana i etahi wa ki te whakakorikori alumina whakahohe, heoi, kaore te tauhohenga methylation e mutu i te wahanga monomethylamine, ka puta he ranunga o te monomethylamine, dimethylamine me te trimethylamine. Whakahaerehia te ōwehenga o te methanol me te haukini, te haukinia te taikaha, me te taapiri i te wai me te tohanga o te trimethylamine he pai ki te hanga o te methylamine me te dimethylamine, ina ko te nui o te haukini he 2.5 wa o te methanol, ko te pāmahana tauhohenga ko te 425 deg C, i te wa o te tauhohenga. te pehanga he 2.45MPa, he amine whakauru o 10-12% o te monomethylamine, 8-9% o Ko te dimethylamine me te 11-13% o te trimethylamine ka taea te whiwhi. I te mea ka hangaia e te trimethylamine he azeotrope me te haukini me etahi atu methylamines i te pehanga o te hau, ka wehea nga hua tauhohenga e te whakakotahitanga o te pehanga pehanga me te tangohanga tangohanga. I runga i te hanga o te 1t whakauru methylamine, 1500kg o te methanol me te 500kg o te haukini wai ka pau. E ai ki nga purongo tuhinga e tika ana, ko te whakarereke i te tauwehenga o te methanol me te haukini he tikanga whai hua ki te tiki i te hua e hiahiatia ana, te methanol me te haukini o te 1:1.5 ko nga tikanga pai mo te hanganga o te trimethylamine, methanol me te haukini o te 1:4. nga tikanga pai mo te hanganga o te methylamine. He maha nga tikanga whakaputa o te monomethylamine, Engari ko te methanol amination te nuinga e whakamahia ana i roto i te ahumahi. CH3OH + NH3 → CH3NH2 + H2O2CH3OH + NH3 →(CH3)2NH + 2H2O3CH3OH + NH3 →(CH3)3N + 3H2O mai i te methanol me te haukini i te ōwehenga o te 1: 1.5~4, i raro i te teitei o te pāmahana me te pehanga teitei, te wahanga hau tonu. kawe te tauhohenga amination catalytic i roto i te whakamahi i te alumina whakahohe hei whakakōkī, Ko te ranunga hua masivesivá o te mono-, di-me trimethylamine ka hangaia, ka wehea e te pehanga Māturu tonu i roto i te raupapa o nga pou Māturu, whātata me deammoniated me dehydrated ki te whiwhi hua mono-, di-me trimethylamine aua. |
