Pakati, kunyanya kune quaternary ammonium compounds;dehydrohalogenating catalyst;corrosion inhibitor;acid neutralizer;potting compounds;zvinonamira;cellulose modifier.
N, N-Dimethylbenzylamine inoshandiswa mukugadzirira bis [(N,N-dimethylamino) benzyl] selenide.Inoshanda sechinhu chinokonzera mukurapa maitiro ekugadzirisa kwe diglycidyl ether ye bisphenol A uye tetrahydrophthalic anhydride.Iyo inopinda inotungamirwa ortho simbi ine butyl lithium.Inopindirana nemethyl iodide kuti iwane ammonium munyu, iyo inoshandiswa sechikamu chekufambisa zvinokonzeresa.Kupfuurirazve, inoshandiswa sechinhu chinokonzeresa kugadzirwa kwe polyurethane foams uye epoxy resins.
N, N-Dimethylbenzylamine yakashandiswa mukugadzirwa kwebis [(N, N-dimethylamino) benzyl] selenide.Iyo yakashandiswa secatalyst panguva yekurapa maitiro ekuumbwa kwe diglycidyl ether ye bisphenol A uye tetrahydrophthalic anhydride.

Kugadzirira: 25% Aqueous Dimethylamine, 1088 gramu

Benzyl Chloride, 126.6 magiramu

Muchigadzirwa cheMuenzaniso 1, benzyl chloride yakawedzerwa zvishoma nezvishoma kwemaawa maviri kune amine (molar ratio 1 kusvika 6) pamwero wakakwana kuchengetedza tembiricha iri pasi pe40°C.Kukurudzira kwakapfuuridzirwa pakamuri tembiricha kweimwe awa kuti inshuwarisi kupedzwa kwekuita kunoratidzwa neiyo equation pazasi.

Mushure mezvo musanganiswa wekuita wakatonhodzwa mumugero wekuparadzanisa umire mufiriji yakachengetedzwa pa 5 ° C. uye yakaparadzaniswa kuita zvidimbu zviviri.Iyo yekumusoro ine mafuta layer, inorema 111.5g, yakabviswa uye mhepo yakanyungudutswa kusvikira pasisina imwe oleaginous chikamu chakaonekwa mune distillate sezvayakauya pamusoro.Iyo isina kuchena distillate yakawanikwa iine 103.5g yeN, N-dimethylbenzylamine (76.1% yedzidziso), 3.3g ye dimethylamine uye isina quaternary munyu.Iyo dimethylamine yakasvibiswa kubva pasi pe29 ° C pasi pekumanikidzwa kwemhepo kubva kuN, N-dimethylbenzylamine (bp 82 ° C / 18mmHg).
