Xog

alaabta ceeriin kiimikaad organic methylamine, oo sidoo kale loo yaqaan methylamine iyo aminomethane, waa walxo kiimiko ah oo muhiim ah oo kiimiko ah iyo dhexdhexaadiye, heerkulka qolka iyo cadaadiska jawiga gaaska aan midabka lahayn, feejignaanta sare ama qulqulka qulqulka, oo leh ur ammonia xooggan. Urta kalluunka oo aad u yar. Ku milmay biyaha, ku milmay ethanol, ether. Fudud in la gubo, samee walxaha qarxa oo hawo leh, xadka qaraxa: 4.3% ~ 21%. Waxaa jira alkaline daciif ah, alkaline ka badan ammonia, iyo aashitada inorganic si ay u soo saaraan milixyada biyaha. Waxay ka samaysan tahay methanol iyo ammonia oo hoos timaada ficilka heerkulka sare iyo cadaadiska sare iyo kicinta, waxaana sidoo kale lagu diyaarin karaa kuleylinta formaldehyde iyo ammonium chloride ilaa 300 ℃ hoos yimaada ficilka zinc chloride. Methylamine waxaa loo isticmaali karaa soo saarida sunta cayayaanka, daawooyinka, xawaareyaasha caagga ah, dheeha, walxaha qarxa, maqaar, batroolka, surfactants, resins sarrifka ion, jeexjeexyada rinjiga, dahaarka iyo waxyaabaha lagu daro. Waa shey ceeriin ah oo muhiim u ah soo saarista sunta cayayaanka Dimethoate, carbaryl iyo chlordimeform. Sunta neefsashada ee Methylamine waa heerka sunta hoose, ugu badnaan la oggol yahay ee hawada 5mg/m3(0.4ppm). Daxal, cuncun indhaha, maqaarka iyo xuubabka. Haddii uu holac furto, waxaa jira khatar gubasho oo uu keeno kuleyl sare, burburka dhululubada iyo qalabyada ayaa sababi doona qarax.
Gargaarka degdega ah ee sumowga Methylamine waa nooc sun ah oo dhexdhexaad ah oo leh xanaaq xooggan iyo daxaluq. Habka wax soo saarka iyo inta lagu jiro gaadiidka, sababtoo ah qulqulka shilalka, waxay keeni doontaa xiriirka sumowga degdega ah.
Alaabtan waxaa lagu nuugi karaa habka neef-mareenka, xalka waxaa lagu nuugi karaa maqaarka, iyo milixdu waxay ku sumeyn kartaa si lama filaan ah. Alaabtani waxay leedahay saameyn xoog leh oo kicinaysa indhaha, mareenka neef-mareenka sare, maqaarka iyo xuubka xuubka. Neefsashada xad-dhaafka badan waxay dhaawici kartaa sambabada. Kiisaska daran waxay sababi karaan barar sambabada, xanuunka neef-mareenka iyo dhimasho. Si kastaba ha ahaatee, ma jiro kiisas ku saabsan sunta habdhiska ah oo laga soo sheegay gudaha iyo dibadda. Xeryahooda dareeraha ah ee methylamine waxay leeyihiin xanaaq xoog leh iyo daxal, waxay sababi karaan gubasho kiimiko ah oo isha iyo maqaarka ah. Xalka aqueous 40% methylamine wuxuu keeni karaa xanuun isha gubanaya, photophobia, ilmada, Conjunctival Congestion, bararka isha daboolka, bararka corneal iyo boogaha dusha sare, calaamaduhu waxay socon karaan 1 ilaa 2 toddobaad. Soo-gaadhista muddada-dheer ee uruurinta hoose ee methylamine-ka, waxay dareemi kartaa indho qalalan, sanka, cunaha iyo raaxo-darrada.
[Calaamadaha gargaarka koowaad]
Marka maqaarku taabto, iska siib dharka wasakhaysan isla markaaba si fiican ugu luqluq biyo badan oo qulqulaya, 0.5% citric acid waxay luqluqdaa maqaarka, xuubka xabka iyo jeexjeexyada.
Marka ay indhuhu wasakhoobaan, daboolka indhaha waa in kor loo qaado, lagu luqluqdo biyo socda ama cusbo leh ugu yaraan 15 daqiiqo, ka dibna lagu baaro fluorescein-ka. Haddii uu jiro dhaawac dhanka maskaxda ah, waa in lala tashado dhakhtarka indhaha.
Kuwa neefsaday gaaska monomethylamine, waa inay si dhakhso ah uga baxaan goobta oo u guuraan meel hawo nadiif ah leh si ay mareenka neefsiga u ilaalinayaan. Dyspnea bukaannada waa in la siiyaa neefsasho oksijiin ah, daawaynta ka dib, bukaanka waxaa loo diray isbitaal si loogu daweeyo degdeg ah.
ujeedo waxaa loo isticmaalaa sida walxaha aasaasiga ah ee dabiiciga ah ee sunta cayayaanka, daawooyinka, dharka iyo warshadaha kale, oo sidoo kale loo isticmaalo walxaha qarxa
loo isticmaalo sida dareere iyo qaboojiye
loo isticmaalo sida walxaha kiimikada ah ee aasaasiga ah, sidoo kale loo isticmaalo sunta cayayaanka, daawooyinka, dharka iyo warshadaha kale
loo isticmaalo sidii surfactant, polymerization inhibitors iyo dareerayaasha, sidoo kale loo isticmaalo soo saarista organic iyo warshadaha daabacaadda iyo midabaynta
loogu talagalay soo saarista sunta cayayaanka waxtarka leh, daawooyinka, dheeha, dhir udgoon, iwm., iyo electrolysis, monomethylamine electroplating waa aliphatic amine organic alaabta ceeriin organic muhiim ah, kaas oo si ballaaran loo isticmaalo in wax soo saarka ee sunta cayayaanka, oo loo isticmaali karaa in lagu soo saaro N- methyl chloroacetamide, kaas oo ah dhexdhexaadiyaha organophosphorus dimethoate iyo omethoate; monocrotophos dhexdhexaad ah α-chloroacetylethanamine; Carbamoyl chloride iyo methyl isocyanate sida dhexdhexaadinta cayayaanka carbamate; Iyo sidoo kale noocyo kale oo sunta cayayaanka ah sida monoformamidine, Amitraz, benzenesulfonon, iwm
Methylamine waxay leedahay codsiyo warshadeed oo ballaaran. Methylamine waxaa loo isticmaali karaa daawo ahaan (firfircooni, caffeine, ephedrine, iwm.), sunta cayayaanka (carbaryl, dimethoate, chloramidine, iwm.), dheeha (alizarin dhexdhexaad ah, dhexdhexaad ah anthraquinone, iwm), qarxa iyo shidaalka (gelka biyaha, monomethhydrazine). iwm.), Surfactants, accelerators, iyo alaabta ceeriin sida caagadaha, kiimikooyinka sawirada iyo dareereyaal.
Dhexdhexaad u ah soo saarista agrochemicals iyo farmashiyaha ee wax soo saarka N-methylpyrrolidone (millaha).
habka wax soo saarka warshad ahaan, methylamine waxaa laga soo saaray methanol iyo ammonia heerkulka sare iyada oo loo marayo beddele kaas oo mararka qaarkood lagu qalabeeyo kicinta alumina ee firfircoon, si kastaba ha ahaatee, falcelinta methylation ma joogsato marxaladda monomethylamine, taas oo keenta isku dhafka monomethylamine, dimethylamine iyo trimethylamine. Xakamaynta saamiga methanol iyo ammonia, xad-dhaafka ammonia, oo ku dar biyo iyo wareegga trimethylamine waxay ku habboon tahay samaynta methylamine iyo dimethylamine, marka qadarka ammonia uu yahay 2.5 jeer methanol, heerkulka falcelinta waa 425 deg C, marka falcelinta Cadaadisku waa 2.45MPa, amin isku dhafan oo ah 10-12% monomethylamine, 8-9% ee dimethylamine iyo 11-13% trimethylamine waa la heli karaa. Maaddaama ay trimethylamine ay sameyso azeotrope leh ammonia iyo methylamines kale ee cadaadiska atmospheric, alaabada falcelinta waxaa lagu kala saaraa isku-darka cadaadiska cadaadiska iyo kala-baxa soosaarka. Iyada oo ku saleysan wax soo saarka 1t methylamine isku dhafan, 1500kg methanol iyo 500kg ammonia dareere ah ayaa la cunaa. Marka loo eego warbixinnada suugaanta khuseeya, beddelidda saamiga methanol iyo ammonia waa hab wax ku ool ah si loo helo badeecada la rabo, methanol iyo ammonia ratio ee 1: 1.5 waa shuruudaha ugu wanaagsan ee samaynta trimethylamine, methanol iyo ammonia saamiga 1: 4 waa shuruudaha ugu fiican ee samaynta methylamine.
Waxaa jira habab badan oo wax-soo-saarka monomethylamine, Laakiin amine methanol waxaa inta badan loo isticmaalaa warshadaha. CH3OH + NH3 → CH3NH2 + H2O2CH3OH + NH3 →(CH3) 2NH + 2H2O3CH3OH + NH3 → (CH3) 3N + 3H2O laga bilaabo methanol iyo ammonia ee saamiga 1: 1.5 ~ 4, heerkulka sare ee joogtada ah iyo cadaadiska wajiga sare, heerkulka sare Dareen-celinta aamin ee catalytic waxaa lagu fuliyaa iyadoo la isticmaalayo firfircoon alumina sida kicinta, Badeecada isku dhafan ee mono-, di-iyo trimethylamine ayaa la soo saaraa, ka dibna waxaa lagu kala saaraa cadaadis joogto ah iyada oo loo marayo tiirar isdaba-joog ah, la shiilay oo la deammoniated iyo fuuqbax si loo helo mono-, di-iyo trimethylamine alaabta siday u kala horreeyaan. .
