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

Kev siv ntawm BDMA

  1. Nruab nrab, tshwj xeeb tshaj yog rau quaternary ammonium tebchaw;dehydrohalogenating catalyst;corrosion inhibitor;acid neutralizer;potting compounds;nplaum nplaum;cellulose modifier.
  2. N, N-Dimethylbenzylamine yog siv rau hauv kev npaj ntawm bis [(N, N-dimethylamino) benzyl] selenide.Nws ua raws li cov catalyst nyob rau hauv kev kho cov tshuaj tiv thaiv ntawm formulations ntawm diglycidyl ether ntawm bisphenol A thiab tetrahydrophthalic anhydride.Nws undergoes qhia ortho metalation nrog butyl lithium.Nws reacts nrog methyl iodide kom tau ammonium ntsev, uas yog siv raws li theem hloov catalysts.Tsis tas li ntawd, nws yog siv los ua ib qho catalyst rau kev tsim ntawm polyurethane foams thiab epoxy resins.
  3. N, N-Dimethylbenzylamine tau siv rau hauv kev sib txuas ntawm bis [(N, N-dimethylamino) benzyl] selenide.Nws tau siv los ua catalyst thaum kho cov tshuaj tiv thaiv ntawm cov qauv ntawm diglycidyl ether ntawm bisphenol A thiab tetrahydrophthalic anhydride.

Kev npaj: 25% Aqueous Dimethylamine, 1088 grams

Benzyl Chloride, 126.6 grams

Nyob rau hauv lub apparatus ntawm Piv txwv 1, benzyl chloride tau ntxiv dropwise nyob rau hauv ob-teev lub sij hawm mus rau amine (molar ratio 1 mus rau 6) ntawm tus nqi txaus los tswj qhov kub ntawm 40 ° C.stirring tau txuas ntxiv nyob rau hauv chav tsev kub rau ib teev ntxiv kom paub tseeb tias ua tiav cov tshuaj tiv thaiv los ntawm qhov sib npaug hauv qab no.

swew

Tom qab ntawd cov tshuaj tiv thaiv sib tov tau txias rau hauv ib qho kev sib cais thaum sawv hauv lub tub yees khaws cia ntawm 5 ° C. thiab sib cais ua ob txheej.Lub sab sauv oily txheej, hnyav 111.5g, raug tshem tawm thiab chav distilled kom txog thaum tsis muaj ntxiv oleaginous tivthaiv tau pom nyob rau hauv lub distillate li nws tuaj.Lub crude distillate tau pom muaj 103.5g ntawm N, N-dimethylbenzylamine (76.1% ntawm txoj kev xav), 3.3g ntawm dimethylamine thiab tsis muaj quaternary ntsev.Lub dimethylamine tau distilled tawm hauv qab 29 ° C nyob rau hauv atmospheric siab los ntawm N, N-dimethylbenzylamine (bp 82 ° C / 18mmHg).
