Iyo CAS nhamba ye triethylenetetramine ndeye 112-24-3, iyo molecular formula ndeye C6H18N4, uye imvura yakareruka yeyero ine yakasimba basicity uye yepakati viscosity.Pamusoro pekushandiswa sechinhu chinonyungudutsa, triethylenetetramine inoshandiswawo mukugadzira epoxy resin kurapa ma agents, metal chelating agents, uye synthetic polyamide resins uye ion exchange resins.

zvinhu zvemuviri
Yakasimba alkaline uye zvine mwero viscous yero mvura, kusagadzikana kwayo kwakaderera pane iyo yediethylenetriamine, asi maitiro ayo akafanana.Boiling point 266-267°C (272°C), 157°C (2.67kPa), kutonhora 12°C, hama density (20, 20°C) 0.9818, refractive index (nD20) 1.4971, flash point 143°C , auto-ignition point 338°C.Soluble mumvura uye ethanol, zvishoma soluble mu ether.Inopisa moto.Low volatility, yakasimba hygroscopicity uye yakasimba alkaline.Inogona kutora carbon dioxide mumhepo.Inopisa, kune njodzi yekutsva kana yakafumurwa nemirazvo yakavhurika nekupisa.Iyo inoparadza zvakanyanya uye inogona kumutsa ganda uye mucous membranes, maziso uye kufema turakiti, uye kukonzera ganda allergies, bronchial asthma uye zvimwe zviratidzo.

makemikari zvinhu
Kupisa (kuora) zvigadzirwa: zvinosanganisira muchetura nitrogen oxides.

Contraindications: acrolein, acrylonitrile, tert-butyl nitroacetylene, ethylene oxide, isopropyl chloroformate, maleic anhydride, triisobutyl aluminium.

Alkali yakasimba: Inomira kana yasangana neokisijeni yakasimba, ichikonzera njodzi yemoto nekuputika.Reacts kana yasangana nenitrogen compounds uye chlorinated hydrocarbons.Inopindirana neasidhi.Hazvienderani neamino compounds, isocyanates, alkenyl oxides, epichlorohydrin, aldehydes, alcohols, ethylene glycol, phenols, cresols, uye caprolactam solutions.Inopindirana ne nitrocellulose.Izvo zvakare hazvienderani neacrolein, acrylonitrile, tert-butyl nitroacetylene, ethylene oxide, isopropyl chloroformate, maleic anhydride, uye triisobutyl aluminium.Inoparadza mhangura, mhangura alloys, cobalt uye nickel.

Shandisa
1. Inoshandiswa seyekamuri tembiricha inorapa epoxy resin;

2. Inoshandiswa se organic synthesis, dhayi yepakati uye zvinonyungudutsa;

3. Inoshandiswa mukugadzira polyamide resins, ion exchange resin, surfactants, lubricant additives, gas purifiers, nezvimwewo;

4. Inoshandiswa sesimbi chelating agent, cyanide-isina electroplating diffusing agent, rubber yekubatsira, inopenya, detergent, dispersing agent, nezvimwewo;

5. Inoshandiswa seyakaomesesa agent, dehydrating agent yealkaline gasi, machira ekupedzisa agent uye synthetic raw material yeion exchanger resin uye polyamide resin;

6. Inoshandiswa se vulcanizing agent ye fluororubber.

Nzira yekugadzira
Nzira yekugadzira ndiyo dichloroethane amination method.Iyo 1,2-dichloroethane uye ammonia mvura yakatumirwa mune tubular reactor yekupisa-kudzvanya ammoniation patembiricha ye150-250 ° C uye kumanikidza kwe392.3 kPa.Mhinduro inogadziriswa inogadziriswa nealkali kuti iwane yakavhenganiswa yemahara amine, iyo yakanamirwa kubvisa sodium chloride, ipapo crude chigadzirwa chinonyungudutswa pasi pekumanikidzwa kwakaderedzwa, uye chikamu chiri pakati pe195-215 ° C. chinopindirwa kuti chiwane chigadzirwa chakapedzwa.Iyi nzira panguva imwe chete inogadzira ethylenediamine;diethylenetriamine;tetraethylenepentamine uye polyethylenepolyamine, iyo inogona kuwanikwa kuburikidza nekudzora tembiricha yeshongwe yekugadziridza kuti inyungurudze musanganiswa weamine, uye kutora zvikamu zvakasiyana zvekuparadzanisa.
