Cov lus txhais

Araldite accelerator 062; aralditeaccelerator 062; Benzenemethamine, N, N-dimethyl-; Benzenemethanamine, N, N-dimethyl-; Benzylamine, N, N-dimethyl-; Benzyl-N, N-dimethylamine; Dabco B-16; N-(Phenylmethyl) dimethylamine

Cov ntawv thov ntawm BDMA

Nruab nrab, tshwj xeeb tshaj yog rau cov tshuaj quaternary ammonium; dehydrohalogenating catalyst; corrosion inhibitor; acid neutralizer; potting compounds; adhesives; cellulose modifier.
N,N-Dimethylbenzylamine yog siv rau hauv kev npaj ntawm bis[(N,N-dimethylamino)benzyl] selenide. Nws ua haujlwm ua tus catalyst hauv kev kho cov tshuaj ntawm diglycidyl ether ntawm bisphenol A thiab tetrahydrophthalic anhydride. Nws dhau los ntawm kev coj ua ortho metalation nrog butyl lithium. Nws reacts nrog methyl iodide kom tau txais ammonium ntsev, uas yog siv ua theem hloov catalysts. Ntxiv mus, nws yog siv ua tus catalyst rau kev tsim cov polyurethane ua npuas ncauj thiab epoxy resins.
N,N-Dimethylbenzylamine tau siv rau hauv kev tsim cov bis[(N,N-dimethylamino)benzyl] selenide. Nws tau siv los ua catalyst thaum lub sijhawm kho cov tshuaj ntawm diglycidyl ether ntawm bisphenol A thiab tetrahydrophthalic anhydride.

Kev Npaj: 25% Aqueous Dimethylamine, 1088 grams

Benzyl Chloride, 126.6 grams

Hauv lub tshuab ntawm Piv Txwv 1, cov benzyl chloride tau ntxiv rau hauv cov amine li ob teev (molar ratio 1 txog 6) ntawm qhov nrawm txaus kom tswj tau qhov kub hauv qab 40°C. Kev do tau txuas ntxiv mus rau qhov kub hauv chav rau ib teev ntxiv kom ntseeg tau tias qhov kev ua tiav ntawm cov tshuaj tiv thaiv uas qhia los ntawm cov qauv hauv qab no.

Tom qab ntawd cov tshuaj sib tov tau txias hauv lub raj xa dej sib cais thaum sawv hauv lub tub yees uas khaws cia ntawm 5 ° C. thiab faib ua ob txheej. Txheej roj sab saud, hnyav 111.5 g, tau raug tshem tawm thiab muab cov pa dej lim kom txog thaum tsis pom muaj cov khoom roj ntxiv hauv cov roj thaum nws los txog. Cov roj lim tau pom tias muaj 103.5 g ntawm N, N-dimethylbenzylamine (76.1% ntawm kev xav), 3.3 g ntawm dimethylamine thiab tsis muaj ntsev quaternary. Cov dimethylamine tau raug lim tawm hauv qab 29 ° C nyob rau hauv lub siab atmospheric los ntawm N, N-dimethylbenzylamine (bp 82 ° C / 18mmHg).
