| Kev piav qhia |
Dimethylaminopropylamine yog aliphatic amine muaj nyob rau hauv amphoteric surfactants xws li kua xab npum thiab tshuaj zawv plaub hau. Nws yog tam sim no raws li impurity lub luag haujlwm rau kev ua xua los ntawm cocamidopropylbetaine. Nws yog structurally zoo li diethylaminopropylamine. Nws kuj yog siv los ua tus neeg sawv cev kho rau epoxy res ins thiab ua cov organic nruab nrab hauv cov tshuaj syntheses (ion exchangers, additives rau flocculants, tshuaj pleev ib ce thiab roj additives, dyes thiab tshuaj tua kab). |
| Chemical Properties |
kua ntshiab. soluble nyob rau hauv dej thiab organic solvents. |
| Siv |
N,N-Dimethyl-1,3-propylenediamine yog ib qho tseem ceeb catalyst rau Knoevenagel condensation. Nws kuj yog ib qho tseem ceeb ntawm cov khoom tawv tawv rau expoxy resin. |
| Siv |
3-(Dimethylamino) propylamine yog ib yam khoom nruab nrab hauv kev sib txuas ntawm alkylamidopropyldimethylamines/alkylamidobetaines; pom raws li ib qho impurity nyob rau hauv cosmetic surfactants muaj nyob rau hauv xws li tshuaj zawv plaub hau; hardener ntawm epoxy resins; additive nyob rau hauv fue!, dyes, tshuaj tua kab thiab binding agents; hauv kev tsim cov ion-exchangers. |
| Siv |
Siv tau rau kev tshem tawm ntawm N-alkylphthalimide derivatives los muab thawj amines, ua lwm txoj rau methyl hydrazine. DMAPA kuj tseem siv ncaj qha los ua cov tawv tawv hauv epoxy resins hauv kev lag luam yas, ua tus neeg sawv cev sib txuas rau cellulose fibers hauv kev lag luam ntawv thiab ua tus neeg sawv cev tiv thaiv rau tawv. Nws yog siv los ua ib qho nruab nrab hauv kev tsim cov khoom sib txuas, cov khoom sib pauv ion, flocculating agents (dej kho), tshuaj pleev ib ce, ntxuav thiab ntxuav cov neeg ua haujlwm (betaines), ntxiv rau roj av thiab lwm yam roj, polyurethane fibers thiab lubricants, dyes, agrochemicals, cov neeg ua haujlwm siv hauv kev yees duab thiab textile kev lag luam. |
| Txoj kev tsim khoom |
3-Dimethylaminopropylamine yog tsim los ntawm kev ntxiv dimethylamine rau acrylonitrile thiab tom qab hydrogenation nyob rau hauv lub xub ntiag ntawm ammonia. |
| Kev piav qhia dav dav |
Dimethylaminopropylamine yog cov kua tsis muaj xim. (NTP, 1992) |
| Cua & Dej Reactions |
Cov nplaim taws heev. Kub rhiab heev thiab tejzaum nws rhiab rau huab cua. Dej soluble. |
| Reactivity Profile |
3-Dimethylaminopropylamine neutralizes acids hauv exothermic cov tshuaj tiv thaiv los tsim cov ntsev ntxiv rau dej. Tej zaum yuav tsis sib haum nrog isocyanates, halogenated organics, peroxides, phenols (acidic), epoxides, anhydrides, thiab acid halides. Flammable gaseous hydrogen tuaj yeem tsim ua ke nrog cov neeg ua haujlwm txo qis, xws li hydrides. |
| Hluav Taws Xob |
3-Dimethylaminopropylamine yog flammable. |
| Toxicology |
Muaj kev qhia txog kev sib cuag thiab tejzaum nws ua pa tsis haum rau kev ua haujlwm. Tsawg dua 0.9 ppm ntawm 3-dimethylaminopropylamine hauv chaw ua haujlwm huab cua tuaj yeem cuam tshuam rau kev ua pa. Lub peev xwm ntawm daim tawv nqaij rhiab heev tau raug txheeb xyuas hauv kev tshawb fawb tsiaj. Hauv qhov ncauj 28-d kev kawm nrog nas (gavage, 7 zaug hauv ib lub lis piam.), cov tsos mob xws li mob ntsws thiab mob plawv tsis ua haujlwm tau sau tseg ntawm 250 mg kg.-1 d -1, tab sis tsis muaj kev cuam tshuam txog kev kho mob ntawm qib 50 mg kg-1 d -1. |
| Kev ruaj ntseg Profile |
Muaj tshuaj lom los ntawm kev noj tshuaj thiab kev sib cuag ntawm daim tawv nqaij. Ib daim tawv nqaij thiab qhov muag irritant. Flammable heev thaum raug tshav kub, nplaim taws, lossis oxidmers. Cov tshuaj tiv thaiv nrog 1,2dichloroethane ua rau cov pa roj acetylene tawg. Qhov no thiab lwm yam amines igmte ntawm kev sib cuag nrog cellulose nitrate ntawm hgh thaj tsam. Txhawm rau tua hluav taws, siv cawv ua npuas ncauj, CO2, tshuaj qhuav. Thaum rhuab mus rau decomposition nws emits cov pa phem ntawm NO,. Saib AMINES thiab |
