Mugadziri Mutengo Wakanaka Dimethylbenzylamine (BDMA) CAS:103-83-3

tsananguro pfupi:

Dimethylbenzylamine (BDMA) imvura isina ruvara kana yero yakapfava ine hwema hwema. Haina kukora zvakanyanya kupfuura mvura uye inonyungudika zvishoma mumvura. Flash point inenge 140°F. Inoparadza ganda, maziso nemukati memucosa. Inokuvadza zvishoma nekumedza, kupinza ganda uye kufema. Inoshandiswa mukugadzira manamatisi nemamwe makemikari.

Mashandisirwo eBDMA

Inoshandiswa pakati nepakati, kunyanya yemakemikari e-quaternary ammonium; dehydrohalogenating catalyst; corrosion inhibitor; acid neutralizer; potting compounds; adhesives; cellulose modifier.
N,N-Dimethylbenzylmine inoshandiswa mukugadzira bis[(N,N-dimethylamino)benzyl] selenide. Inoshanda se catalyst mu clining reaction ye diglycidyl ether ye bisphenol A uye tetrahydrophthalic anhydride. Inopinda directed ortho metalation ne butyl lithium. Inosangana ne methyl iodide kuti iwane ammonium salt, iyo inoshandiswa se phase transfer catalysts. Uyezve, inoshandiswa se catalyst yekuumbwa kwe polyurethane foams uye epoxy resins.
N,N-Dimethylbenzylmine yakashandiswa mukugadzirwa kwebis[(N,N-dimethylamino)benzyl] selenide. Yakashandiswa se catalyst panguva yekurapa kwe diglycidyl ether ye bisphenol A uye tetrahydrophthalic anhydride.

Kugadzirira: 25% Dimethylamine yemvura, 1088 magiramu

Benzyl Chloride, 126.6 magiramu

Muchishandiso cheMuenzaniso 1, benzyl chloride yakawedzerwa dropwise kwenguva yemaawa maviri kuamine (molar ratio 1 kusvika 6) nechiyero chakakwana kuchengetedza tembiricha iri pasi pe40°C. Kukurunga kwakaramba kuripo patembiricha yemukamuri kweawa imwe chete kuti kuve nechokwadi chekuti reaction inoratidzwa ne equation iri pazasi yapera.

Mushure mezvo musanganiswa we reaction wakatonhodzwa mu separatory funnel wakamira mufiriji yakachengetwa pa5°C. ndokukamurwa kuita zvikamu zviviri. Chikamu chepamusoro chemafuta, chinorema 111.5g, chakabviswa ndokunyungudutswa nemhepo kusvika pasisina chimwe chikamu che oleaginous chakaonekwa mu distillate payakasvika. Distillate isina kuchena yakawanikwa ine 103.5g yeN,N-dimethylbenzylamine (76.1% yedzidziso), 3.3g yedimethylamine uye isina quaternary salts. Dimethylamine yakanyungudutswa pasi pe29°C pasi pekumanikidzwa kwemhepo kubva kuN,N-dimethylbenzylamine (bp 82°C/18mmHg).
