ʻO Tetraethylenepentamine, i ʻike ʻia hoʻi ʻo tritetraethylenediamine, i hoʻopōkole ʻia ʻo TEPA, he wai ʻālohilohi melemele a ʻalani paha. Hoʻoheheʻe maʻalahi i ka wai, ethanol a me ka hapa nui o nā mea hoʻoheheʻe organik, ʻaʻole hoʻoheheʻe ʻia i ka benzene a me ka ether. Hoʻopili maʻalahi ia i ka wai a me ke kalapona dioxide i ka lewa. Alkaline. Loaʻa ia ma o ka amination thermal a me ka hopena ammonolysis ma waena o dichloroethane a me ammonia, neutralizing me ka alkali a laila distilling ma lalo o ke kaomi i hoʻemi ʻia. Hoʻohana ʻia ma ke ʻano he hopena paʻa chromatography gas no ka paʻa koho a me ka hoʻokaʻawale ʻana o nā alcohols, amines, pyridine, quinoline, piperazine, thiols a me ka wai. Hoʻohana ʻia i loko o nā resins hoʻololi anion, nā mea hoʻohui aila lubricating, nā mea hoʻohui aila wahie, a hoʻohana pū ʻia hoʻi ma ke ʻano he epoxy resin curing agents, rubber vulcanization accelerators, etc.

Kumu

Hiki ke hoʻohana ʻia ʻo Tetraethylene pentamine no ka titration paʻakikī o ke keleawe, zinc a me ka nickel ma o ke ʻano hopena o kēia manawa, saponification o nā mea waikawa, synthetic rubber a me ka resin gas purification a me ka dehydration agent. Hoʻohana pū ʻia e like me nā mea hoʻohui, nā mea hoʻōla, nā mea hoʻolalelale, a me nā mea hoʻonui.

ʻAno hana:

He huahana like kēia huahana o ka ethylenediamine, diethylenetriamine, triethylenetetramine, a me ka polyethylenepolyamine. No nā loina hana a me nā hana, e ʻoluʻolu e nānā i ka ethylenediamine. Eia nō naʻe, pono ka mahana o ka hopena ammonolysis ma waena o 160 a 250°C, a ʻoi aku ke kaomi ma mua o 4.0MPa. E hoʻoheheʻe i ka huahana polyamine maka ma lalo o ke kaomi i hoʻemi ʻia, e hōʻiliʻili i nā ʻāpana ma 160-210°C ma lalo o ke kaomi o 1.3kPa, a loaʻa ka huahana i hoʻopau ʻia o ka tetraethylpentamine ma hope o ka hoʻomaʻalili ʻana. ʻAno hoʻomaʻemaʻe: E hoʻomaloʻo me ka sodium metala a i ʻole ka calcium sulfate anhydrous a laila e hoʻokaʻawale ma lalo o ke kaomi i hoʻemi ʻia. Hiki iā ʻoe ke hoʻoheheʻe i 150g o ka tetraethylenepentamine i loko o 300mL o 95% ethanol, a e hoʻokuʻu mālie i loko o 180mL o ka waikawa hydrochloric i hoʻopaʻa ʻia i ka wā e hoʻomaʻalili ana, e mālama ana i ka mahana ma lalo o 20°C. E kānana i ka mea i hoʻokahe ʻia keʻokeʻo, e hana hou iā ia i ʻekolu manawa me ka hui ʻana o ka ethanol a me ka wai, holoi me ka ether, a hoʻomaloʻo ma lalo o ka vacuum e loaʻa ai ka tetraethylenepentamine hydrochloride maʻemaʻe.
