Tetraethylenepentamine, inozivikanwawo se tritetraethylenediamine, yakapfupikiswa se TEPA, imvura ine ruvara rweyero kana orenji-tsvuku. Inonyungudika nyore nyore mumvura, ethanol uye zvakawanda zvinonyungudutsa, hainyungudike mu benzene ne ether. Inonyungudika nyore nyore mumvura uye carbon dioxide mumhepo. Alkaline. Inowanikwa nekupisa uye ammonolysis reaction pakati pe dichloroethane ne ammonia, ichinyorovesa ne alkali uye yozonyungudika pasi pekumanikidzwa kwakaderera. Inoshandiswa se gas chromatography stationary solution yekuchengetedza uye Chemicalbook kupatsanurwa kwealcohols, amines, pyridine, quinoline, piperazine, thiols nemvura. Inoshandiswa mu anion exchange resins, lubricating oil additives, fuel oil additives, uye inoshandiswawo se epoxy resin curing agents, rubber vulcanization accelerators, nezvimwewo.

Chinangwa

:Tetraethylene pentamine inogona kushandiswa pakuwedzera mhangura, zinc uye nickel nenzira yemazuva ano, saponification yezvinhu zvine acidic, synthetic rabber ne resin gas cleansing uye dehydration agent. Inoshandiswawo sekuwedzera, curing agents, accelerators, nezvimwewo.

Nzira yekugadzira:

Chigadzirwa ichi chinobva mu ethylenediamine, diethylenetriamine, triethylenetetramine, uye polyethylenepolyamine. Kuti uwane misimboti yekugadzira uye mashandiro, ndapota tarisa ethylenediamine. Zvisinei, tembiricha yeammonolysis reaction inofanirwa kuva 160 kusvika 250°C, uye kumanikidzwa kunofanira kunge kuri pamusoro pe4.0MPa. Dururira chigadzirwa chepolyamine chisina kusimba pasi pekumanikidzwa kwakaderera, unganidza zvikamu pa160-210°C pasi pekumanikidzwa kwe1.3kPa, uye tora chigadzirwa chakapedzwa. Chemicalbook of tetraethylpentamine mushure mekutonhora. Nzira yekunatsa: Sungunusa nemvura nesimbi sodium kana anhydrous calcium sulfate wobva waparadzanisa pasi pekumanikidzwa kwakaderera. Unogona zvakare kunyungudutsa 150g ye tetraethylenepentamine mu300mL ye95% ethanol, wobva waderedza zvishoma nezvishoma 180mL ye concentrated hydrochloric acid uku uchitonhora, uchichengetedza tembiricha iri pasi pe20°C. Sefa ganda jena, worisanganisa katatu nemusanganiswa weethanol nemvura, wosuka ne ether, wozoomesa pasi pe vacuum kuti uwane tetraethylenepentamine hydrochloride yakachena.
