Tetraethylammonium bromideCAS71-91-0

Amfani

1. Mai kara kuzari na canja wurin lokaci - Tetraethylammonium bromide wani mai kara kuzari ne da ake amfani da shi wajen canza yanayin yanayi a cikin halayen hada kwayoyin halitta. Misali, a cikin martanin da ke tsakanin halogenated hydrocarbons da nucleophilic reagents, yana iya haɓaka yanayin yanayi. A cikin halayen alkylation, lokacin da halogenated alkanes ke amsawa da mahadi da ke ɗauke da hydrogen mai aiki (kamar phenols, alcohols, carboxylic acid, da sauransu), tetraethylammonium bromide na iya sa yanayin yanayi ya faru a ƙarƙashin yanayi mai sauƙi. Domin yana iya taimakawa masu kara kuzari na nucleophilic su canza daga matakin ruwa zuwa matakin kwayoyin halitta, wanda hakan ke sa yanayin ya ci gaba cikin sauƙi a cikin yanayin kwayoyin halitta. Misali, a cikin martanin alkylation na phenylacetonitrile tare da halogenated alkanes, tetraethylammonium bromide na iya ƙara yawan yanayin yanayi yadda ya kamata.

2. Reagent na ion pair chromatography - Tetraethylammonium bromide yana taka muhimmiyar rawa a matsayin reagent na ion pair a cikin ion pair chromatography. Yana iya samar da nau'ikan ion tare da analytes tare da caji akasin haka, ta haka yana canza halayen riƙewa na analytes. Lokacin nazarin mahadi kamar tushen halitta ko acid na halitta, ta hanyar daidaita yawan tetraethylammonium bromide, ana iya inganta yanayin rabuwar chromatographic. Misali, lokacin nazarin wasu alkaloids, yana iya samar da nau'ikan ion tare da cations na alkaloid, don haka alkaloids suna da lokacin riƙewa mai dacewa akan ginshiƙin chromatographic mai juyawa, ta haka ne suke cimma mafi kyawun tasirin rabuwa.

3. Surfactant - Haka kuma ana iya amfani da shi azaman cationic surfactant. A wasu halayen polymerization na emulsion, tetraethylammonium bromide na iya rage tashin hankali a saman kuma yana ba da damar monomers su warwatse a cikin tsarin amsawa. Misali, a cikin polymerization na emulsion na styrene, ƙara adadin tetraethylammonium bromide mai dacewa zai iya sa digo na styrene su warwatse daidai gwargwado, wanda ke taimakawa ga ci gaban polymerization reaction kuma yana iya inganta kwanciyar hankali na polymer emulsion.

4. Sauran aikace-aikace - A fannin electrochemistry, ana iya amfani da tetraethylammonium bromide a matsayin wani ɓangare na electrolytes. A wasu batura ko na'urori masu auna electrochemical, yana iya samar da tashoshin ion conduction. Misali, a wasu na'urori masu auna electrochemical bisa ga membranes na ion exchange, tetraethylammonium bromide na iya taimakawa wajen kula da daidaiton ion a ɓangarorin biyu na membrane, ta haka ne za a tabbatar da aikin na'urar yadda ya kamata.

Marufi da Jigilar Kaya

25KG/Drum ko kuma kamar yadda ake buƙata daga abokin ciniki.

Jigilar kaya: nau'ikan kayayyaki masu haɗari guda 6 kuma ana iya isar da su ta teku.

Ajiyewa da adanawa

Rayuwar shiryayye: Watanni 24 daga ranar ƙera shi a cikin marufi na asali wanda ba a buɗe ba, an adana shi a wuri mai sanyi da bushewa, ba tare da hasken rana kai tsaye ba, ko ruwa.
Ma'ajiyar iska, Busar da ƙananan zafin jiki, An raba shi da sinadarai masu guba, acid.
