ʻO ka Tetraethylammonium bromide CAS71-91-0

Hoʻohana

1. Mea hoʻouluulu hoʻoili pae - ʻO Tetraethylammonium bromide kahi mea hoʻouluulu hoʻoili pae i hoʻohana pinepine ʻia i nā hopena synthesis organik. No ka laʻana, i ka hopena ma waena o nā hydrocarbons halogenated a me nā reagents nucleophilic, hiki iā ia ke hoʻolaha i ka hopena. I nā hopena alkylation, i ka wā e hana ai nā alkanes halogenated me nā hui i loaʻa ka hydrogen hana (e like me nā phenols, alcohols, carboxylic acids, etc.), hiki i ka tetraethylammonium bromide ke hana i ka hopena ma lalo o nā kūlana akahai. No ka mea hiki iā ia ke kōkua i nā reagents nucleophilic e hoʻoili mai ka pae wai i ka pae organik, e hoʻomau mālie ai ka hopena i ka pae organik. No ka laʻana, i ka hopena alkylation o phenylacetonitrile me nā alkanes halogenated, hiki i ka tetraethylammonium bromide ke hoʻonui pono i ka hopena hopena.

2. ʻO ka mea hana chromatography pālua ion - He kuleana koʻikoʻi ko Tetraethylammonium bromide ma ke ʻano he mea hana pālua ion i ka chromatography pālua ion. Hiki iā ia ke hana i nā pālua ion me nā analytes me nā uku kū'ē, a laila e hoʻololi ana i ke ʻano paʻa o nā analytes. I ka wā e kālailai ai i nā hui e like me nā kumu organik a i ʻole nā ​​​​waikawa organik, ma ka hoʻoponopono ʻana i ka nui o ka tetraethylammonium bromide, hiki ke hoʻomaikaʻi ʻia nā kūlana hoʻokaʻawale chromatographic. No ka laʻana, i ka wā e kālailai ai i kekahi mau alkaloids, hiki iā ia ke hana i nā pālua ion me nā cations alkaloid, i loaʻa i nā alkaloids kahi manawa paʻa kūpono ma ke kolamu chromatographic i hoʻohuli ʻia, a laila e hoʻokō ai i nā hopena hoʻokaʻawale maikaʻi aʻe.

3. Surfactant - Hiki ke hoʻohana ʻia ma ke ʻano he surfactant cationic. I kekahi mau hopena polymerization emulsion, hiki i ka tetraethylammonium bromide ke hōʻemi i ka ʻili o ka ʻili a hiki i nā monomers ke hoʻopuehu maikaʻi ʻia i loko o ka ʻōnaehana hopena. No ka laʻana, i ka polymerization emulsion o styrene, ʻo ka hoʻohui ʻana i kahi nui kūpono o ka tetraethylammonium bromide hiki ke hoʻopuehu like i nā kulu styrene, kahi mea e kōkua ai i ka holomua o ka hopena polymerization a hiki ke hoʻomaikaʻi i ke kūpaʻa o ka emulsion polymer.

4. Nā noi ʻē aʻe - Ma ke kahua o ka electrochemistry, hiki ke hoʻohana ʻia ka tetraethylammonium bromide ma ke ʻano he ʻāpana o nā electrolytes. I loko o kekahi mau pila a i ʻole nā ​​​​mea ʻike electrochemical, hiki iā ia ke hāʻawi i nā kahawai hoʻoili ion. No ka laʻana, i loko o kekahi mau mea electrochemical e pili ana i nā membrane hoʻololi ion, hiki i ka tetraethylammonium bromide ke kōkua i ka mālama ʻana i ke kaulike ion ma nā ʻaoʻao ʻelua o ka membrane, no laila e hōʻoiaʻiʻo ana i ka hana maʻamau o ka hāmeʻa.

ʻŌpala a me ka Hoʻouna ʻana

25KG/Drum a i ʻole e like me nā koi a ka mea kūʻai aku.

Hoʻouna: 6 ʻano waiwai weliweli a hiki ke hoʻouna ma ke kai.

Mālama a me ka mālama ʻana

Ola papa: 24 mahina mai ka lā i hana ʻia ai i loko o ka pahu i wehe ʻole ʻia mua i mālama ʻia i kahi maloʻo a me kahi anuanu, mai ka lā pololei, ka wai.
Hale kūʻai ea, hoʻomaloʻo wela haʻahaʻa, hoʻokaʻawale ʻia mai nā mea hoʻomake a me nā waikawa.
