Umenzi wexabiso eliLungileyo iDimethylbenzylamine (BDMA) CAS:103-83-3

inkcazelo emfutshane:

I-Dimethylbenzylamine (BDMA) lulwelo olungenambala ukuya kumthubi olukhanyayo kunye nevumba elimnandi.Ixinene kancinci kunamanzi kwaye inyibilika kancinane emanzini.Indawo yokudanyaza malunga ne-140°F.Igqwesa ulusu, amehlo kunye nenwebu.Ityhefu kancinci ngokutya, ukufunxa ulusu kunye nokuphefumla.Isetyenziselwa ukwenza izinto zokuncamathelisa kunye nezinye iikhemikhali.

Usetyenziso lwe-BDMA

Phakathi, ngokukodwa kwiikhompawundi ze-quaternary ammonium;i-dehydrohalogenating catalyst;i-corrosion inhibitor;i-acid neutralizer;iikhompawundi zembiza;izinto zokuncamathelisa;isilungisi selulosi.
I-N, N-Dimethylbenzylamine isetyenziselwa ukulungiswa kwe-bis [(N, N-dimethylamino) benzyl] selenide.Isebenza njenge-catalyst ekuphenduleni kokunyanga kwe-formulations ye-diglycidyl ether ye-bisphenol A kunye ne-tetrahydrophthalic anhydride.Ihamba nge-ortho metalation eyalelweyo kunye ne-butyl lithium.Idibana ne-methyl iodide ukufumana ityuwa ye-ammonium, esetyenziswa njengezinto zokudlulisa isigaba.Ngapha koko, isetyenziswa njenge-catalyst yokwenziwa kwe-polyurethane foams kunye ne-epoxy resins.
I-N, N-Dimethylbenzylamine isetyenziswe kwi-synthesis ye-bis [(N, N-dimethylamino) benzyl] selenide.Isetyenziswe njenge-catalyst ngexesha lokunyanga ukusabela kokwenziwa kwe-diglycidyl ether ye-bisphenol A kunye ne-tetrahydrophthalic anhydride.

Ukulungiselela: 25% iDimethylamine enamanzi, i-1088 grams

I-Benzyl Chloride, i-126.6 grams

Kwisixhobo soMzekelo 1, i-benzyl chloride yongezwa ngokwehla kwisithuba seyure ezimbini kwi-amine (i-molar ratio 1 ukuya ku-6) ngesantya esaneleyo ukugcina ubushushu obungaphantsi kwama-40°C.Ukuvuselela kwaqhutyekwa kwiqondo lobushushu begumbi kwiyure eyongezelelweyo ukuqinisekisa ukugqitywa kwempendulo echazwe yi-equation engezantsi.

Emva koko umxube we-reaction upholile kwi-funnel yokwahlula ngelixa umi kwifriji egcinwe kwi-5 ° C. kwaye yahlulwa ibe ngamacandelo amabini.Umaleko onamafutha aphezulu, anobunzima be-111.5g, yasuswa kwaye i-steam distilled de kungabikho nxalenye ye-oleaginous yabonwa kwi-distillate njengoko ifika.I-distillate ekrwada yafunyanwa iqulethe i-103.5g ye-N, N-dimethylbenzylamine (i-76.1% yethiyori), i-3.3g ye-dimethylamine kwaye ayikho i-quaternary salts.I-dimethylamine yachithwa ngaphantsi kwe-29 ° C phantsi koxinzelelo lwe-atmospheric ukusuka kwi-N, N-dimethylbenzylamine (bp 82 ° C / 18mmHg).
