ʻO Tetraethylenepentamine, i kapa ʻia hoʻi ʻo tritetraethylenediamine, a i ʻole TEPA, he wai syrup melemele a ʻalani-ʻulaʻula paha me ka waiwai hoʻokahi. He maʻalahi ia e hoʻoheheʻe ʻia i ka wai, ka waiʻona ethyl, a me ka hapa nui o ka mea hoʻoheheʻe organik, akā ʻaʻole hiki ke hoʻoheheʻe ʻia i ka benzene a me ka quintessence. ʻO kēia hui e hoʻopili i ka hiki ke omo i ka wai a me ke kalapona dioxide mai ka lewa, e hoʻolālā ana iā ia he alkaline ma ke ʻano. Hoʻohana pinepine ʻia ʻo TEPA i nā noi like ʻole e like me ka chromatography gas stationary solution no ka mālama koho ʻana a me ka hoʻokaʻawale ʻana i nā hui like ʻole e like me ka waiʻona, amine, pyridine, quinoline, piperazine, thiols, a me ka wai. Hoʻohana pū ʻia ia i loko o ka resin hoʻololi anion, lubricate oil additive, fuel oil additive, a lawelawe ma ke ʻano he epoxy resin hardening agent a me nā rubber vulcanization accelerators.

Pahuhopu:Ua ʻike ʻia ʻo Tetraethylenepentamine i kona hoʻohana ʻana i ka titration paʻakikī o nā mea metala e like me ke keleawe, zinc, a me ka nickel e hoʻohana ana i ke ʻano hopena o kēia manawa. Hoʻohana ʻia nō hoʻi ia i ka saponification o ka mea waikawa, ka hoʻomaʻemaʻe kinoea, ka mea hoʻoheheʻe wai, ka rubber synthetic, a me ka noi resin. Eia kekahi, hoʻohana ʻia ʻo TEPA ma ke ʻano he mea hoʻohui, mea hoʻopaʻakikī, a me ka mea hoʻolalelale i nā ʻoihana like ʻole.

ʻO ka hana ʻana o ka tetraethylenepentamine e pili ana i nā ʻanuʻu he nui a he carbon monoxide-merchandise o ethylenediamine, diethylenetriamine, triethylenetetramine, a me polyethylenepolyamine. ʻO ke ʻano hana e komo pū me ka amination thermal a me ka ammonolysis chemical reaction, neutralization, a me ka distillation ma lalo o ke kaomi hoʻemi. ʻO ke kaʻina hana hoʻomaʻemaʻe e pili ana i ka dehydration, fractionation ma lalo o ke kaomi hoʻemi, a me ka recrystallization no ka loaʻa ʻana o ka tetraethylenepentamine hydrochloride maʻemaʻe. Me ke kaumaha molekala o 189.3 a me ka helu calcium 112-57-2, ʻo ka kihi hola TEPA kahi kiko paila o 340 ° degere centigrade, kahi density o 0.998g / milliliter ma 25 ° degere centigrade, a me kahi kiko flash o 365 ° F.

hoʻomaopopo ʻananūhou ʻoihanaHe mea koʻikoʻi ia no ka mea hoʻopukapuka kālā, ʻoihana, a me ka ʻoihana ma nā ʻoihana like ʻole. Ma ka noho ʻana i ka ʻike e pili ana i ke ʻano o ka mākeke, ka papa kuhikuhi waiwai, a me ka hoʻopou hou ʻana o ka ʻoihana, hiki i ke kanaka ke hoʻoholo maikaʻi i ka hoʻopukapuka kālā, ka hui pū ʻana, a me ka hoʻolālā ʻoihana. e kālailai i ka ʻikepili, wānana i ka neʻe ʻana o ka mākeke, a me ka hoʻomaopopo ʻana i ka hopena o ka hanana honua ma ka ʻoihana hiki ke kōkua i ke kanaka e holo i ke ʻano o ka mana morale o ke ao holoʻokoʻa ʻoihana me ka maikaʻi. e noho i ka hoʻopou hou ʻana me nā hoʻomohala hou loa i nā nūhou ʻoihana e noho i mua i ke kaiapuni mākeke hoʻokūkū.
