Cov ntawv thov ntawm BDMA

Nruab nrab, tshwj xeeb tshaj yog rau cov quamary ammonium sib xyaw; dehydrohalogenating catalyst; corrosion inhibitor; Acid neutorizer; Potting potting; Cov nplaum; cellulose hloov kho.
N, n-dimethylblukylamine siv nyob rau hauv kev npaj ntawm bis [(n, n-dimethylamino) benzylite selenide. Nws ua raws li kev tshuaj ntsuam ntawm kev kho cov tshuaj tiv thaiv ntawm cov qauv ntawm diglycidy ether ntawm bisphenol a thiab tetrahydrophthalic anhydride. Nws undergoes qhia ortho hlau nrog butyl lithium. Nws reacts nrog methyl iodide kom tau txais ammonium ntsev, uas yog siv los ua theem hloov catalysts. Ntxiv mus, nws yog siv los ua catalyst rau kev tsim cov polyurethane ua npuas thiab epoxy resins.
N, n-dimethylbzylamine tau siv nyob rau hauv synthesis ntawm bis [(n, n-dimethylamino) selenide. Nws tau siv ua catalyst thaum lub sij hawm kho cov tshuaj tiv thaiv ntawm cov qauv ntawm diglycidy ether ntawm bisphenol a thiab tetrahydrothhalic anhydride.

Kev npaj: 25% aqueous dimetylamine, 1088 grams

Benzyl chloride, 126.6 grams

Hauv Apparatus ntawm Piv Txwv 1, Benzyl Clandoride tau ntxiv droporide dhau ib lub amine (molield ib lub sijhawm 1 txog 6) ntawm tus nqi txaus kom muaj qhov kub thiab txias dua 40 ° C. Stirring tau txuas ntxiv nyob rau hauv chav tsev kub rau ib teev ntxiv rau kev ua kom tiav qhov kev tawm tsam denoted los ntawm kab zauv hauv qab no.

Tom qab cov tshuaj tiv thaiv cov tshuaj tiv thaiv tau txias rau hauv kev sib cais funnel thaum sawv hauv lub tub yees kom sawv ntawm 5 ° C. thiab sib cais ua ob txheej. Cov roj ntoo loj dua, hnyav 111.5g, tau raug tshem tawm thiab ua pa tawm kom txog thaum tsis muaj kev sib xyaw ua ke ntxiv rau hauv cov distillate raws li nws tau tuaj tshaj. Lub crude distillate tau pom muaj 103.5g ntawm n, n-dimethylblamine (76.1% ntawm Dimethylamine thiab tsis muaj CHENETYYNAMINE thiab tsis muaj CHANNYYRY. Lub dimethylamine tau distilled tawm hauv qab 29 ° C nyob rau hauv atmospheric siab los ntawm n, n-detethylblulamine (BP 82 ° C / 18mmHG).
