I-Tetraethylenepentamine, ekwaziwa ngokuba yi-tritetraethylenediamine, efinyeziweyo njenge-TEPA, lulwelo oluthambileyo olutyheli okanye olubomvu-orenji. Lunyibilika lula emanzini, kwi-ethanol nakwizinto ezininzi ezinyibilikayo, alunyibiliki kwi-benzene nakwi-ether. Lufunxa lula amanzi kunye ne-carbon dioxide emoyeni. I-Alkaline. Ifunyanwa ngokusabela kobushushu kunye ne-ammonolysis phakathi kwe-dichloroethane kunye ne-ammonia, luyinciphisa nge-alkali ize inyibilikiswe phantsi koxinzelelo oluphantsi. Isetyenziswa njengesisombululo se-gas chromatography esisisigxina sokugcina izinto kunye nokwahlula i-Chemicalbook ye-alcohols, i-amines, i-pyridine, i-quinoline, i-piperazine, i-thiols kunye namanzi. Isetyenziswa kwi-anion exchange resins, kwi-lubricating oil additives, kwi-fuel oil additives, kwaye ikwasetyenziswa njenge-epoxy resin curing agents, i-rubber vulcanization accelerators, njl.

Injongo

I-Tetraethylene pentamine ingasetyenziselwa i-complex titration ye-copper, i-zinc kunye ne-nickel ngendlela yangoku, i-saponification yezinto ezine-asidi, irabha yokwenziwa kunye ne-resin gas cleansing kunye ne-dehydration agent. Ikwasetyenziswa njengezongezo, ii-curing agents, ii-accelerators, njl.njl.

Indlela yokuvelisa:

Le mveliso yimveliso edibeneyo ye-ethylenediamine, i-diethylenetriamine, i-triethylenetetramine, kunye ne-polyethylenepolyamine. Ngemigaqo yokuvelisa kunye nokusebenza, nceda ubhekisele kwi-ethylenediamine. Nangona kunjalo, ubushushu be-reaction ye-ammonolysis kufuneka bube yi-160 ukuya kwi-250°C, kwaye uxinzelelo kufuneka lube ngaphezulu kwe-4.0MPa. Hlanza imveliso ye-polyamine ekrwada phantsi koxinzelelo oluncitshisiweyo, qokelela amaqhezu kwi-160-210°C phantsi koxinzelelo lwe-1.3kPa, kwaye ufumane imveliso egqityiweyo. Incwadi yeChemicalbook ye-tetraethylpentamine emva kokupholisa. Indlela yokucoca: Khipha amanzi nge-sodium yesinyithi okanye i-calcium sulfate engamanzi uze uwaqhekeze phantsi koxinzelelo oluncitshisiweyo. Unganyibilikisa i-150g ye-tetraethylenepentamine kwi-300mL ye-95% ye-ethanol, kwaye kancinci kancinci wehlise i-180mL ye-hydrochloric acid exineneyo ngelixa uphola, ugcine ubushushu bungaphantsi kwe-20°C. Hluza i-white precipitate, uyiphinde uyifake icrystall kathathu ngomxube we-ethanol namanzi, uhlambe nge-ether, uze uyomise phantsi kwe-vacuum ukuze ufumane i-tetraethylenepentamine hydrochloride ecocekileyo.
